    Methods developed for mapping the journal structures contained in aggregated journal-journal citations in the Science Citation Index are applied to the Chinese Science Citation Database of the Chinese Academy of Sciences. This database covers 991 journals, of which only 37 had originally English titles. Using factor-analytical and graph-analytical techniques we show that this data is dually structured. The main structure is the intellectual organization of the journals in journal groups (as in the international SCI), but the university-based journals provide an institutional layer that orients this structure towards practical ends (e.g., agriculture). The Chinese Science Citation Database exhibits the characteristics of Mode 2 in the production of scientific knowledge more than its western counterparts. The contexts of application lead to correlation (interfactorial complexity) among the components.

  2. Colil: a database and search service for citation contexts in the life sciences domain.

    To promote research activities in a particular research area, it is important to efficiently identify current research trends, advances, and issues in that area. Although review papers in the research area can suffice for this purpose in general, researchers are not necessarily able to obtain these papers from research aspects of their interests at the time they are required. Therefore, the utilization of the citation contexts of papers in a research area has been considered as another approach. However, there are few search services to retrieve citation contexts in the life sciences domain; furthermore, efficiently obtaining citation contexts is becoming difficult due to the large volume and rapid growth of life sciences papers. Here, we introduce the Colil (Comments on Literature in Literature) database to store citation contexts in the life sciences domain. By using the Resource Description Framework (RDF) and a newly compiled vocabulary, we built the Colil database and made it available through the SPARQL endpoint. In addition, we developed a web-based search service called Colil that searches for a cited paper in the Colil database and then returns a list of citation contexts for it along with papers relevant to it based on co-citations. The citation contexts in the Colil database were extracted from full-text papers of the PubMed Central Open Access Subset (PMC-OAS), which includes 545,147 papers indexed in PubMed. These papers are distributed across 3,171 journals and cite 5,136,741 unique papers that correspond to approximately 25 % of total PubMed entries. By utilizing Colil, researchers can easily refer to a set of citation contexts and relevant papers based on co-citations for a target paper. Colil helps researchers to comprehend life sciences papers in a research area more efficiently and makes their biological research more efficient.

    2013-01-01

    Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

    2009-11-01

    The paper analyzes the level of coverage and citation of publications by mechanicians of the National Academy of Sciences of Ukraine (NASU) in the Scopus database. Two groups of mechanicians are considered. One group includes 66 doctors of sciences of the S. P. Timoshenko Institute of Mechanics as representatives of the oldest institute of the NASU. The other group includes 34 members (academicians and corresponding members) of the Division of Mechanics of the NASU as representatives of the authoritative community of mechanicians in Ukraine. The results are presented for each scientist in the form of two indices—the total number of publications accessible in the database as the level of coverage of the scientist's publications in this database and the h-index as the citation level of these publications. This paper may be considered to continue the papers [6-12] published in Prikladnaya Mekhanika (International Applied Mechanics) in 2005-2009

    It is essential to evaluate the impact of scientific publications through citation analysis in citation indexes. In addition, scientometric measures of social media also should be assessed. These measures include how many times the publications were read, viewed, and downloaded. The present study aimed to assess the scientific output of scholars at Kashan University of Medical Sciences by the end of March 2014 based on scientometric measures of Scopus, ResearchGate, and Mendeley. A survey method was used to study the articles published in Scopus journals by scholars at Kashan University of Medical Sciences by the end of March 2014. The required data were collected from Scopus, ResearchGate, and Mendeley. The data were analyzed with descriptive statistics. Also, the Spearman correlation was used between the number of views of articles in ResearchGate with citation number of the articles in Scopus and reading frequency of the articles in Mendeley with citation number in Scopus were examined using the Spearman correlation in SPSS 16. Five-hundred and thirty-three articles were indexed in the Scopus Citation Database by the end of March 2014. Collectively, those articles were cited 1,315 times. The articles were covered by ResearchGate (74%) more than Mendeley (44%). In addition, 98% of the articles indexed in ResearchGate and 92% of the articles indexed in Mendeley were viewed at least once. The results showed that there was a positive correlation between the number of views of the articles in ResearchGate and Mendeley and the number of citations of the articles in Scopus. Coverage and the number of visitors were higher in ResearchGate than in Mendeley. The increase in the number of views of articles in ResearchGate and Mendeley also increased the number of citations of the papers. Social networks, such as ResearchGate and Mendeley, also can be used as tools for the evaluation of academics and scholars based on the scientific research they have conducted.

    The online information resources available to the CERN Community have recently increased by an additional database: Web of Science. WoS is a collection of several databases, among them the Science Citation Index, the Conference Proceedings Index and the Journal Citation Reports. The first two products allow you to perform subject, author and title searches, and most importantly you can obtain a list of papers citing a specific article, or navigate to the articles cited by the same article. Besides the retrieval and navigation features, analytical tools allow you to produce statistics and graphs describing the impact of a publication. Finally, the Journal Citation Reports database provides you with the well known – and often disputed – Impact Factor.

    2012-03-01

    Citation analysis is currently one of the most widely used metrics for analyzing the scientific contribution in different fields. The Islamic World Science Citation Center (ISC) aims at promoting technical cooperation among Muslim scientists and their respected centers based on these theories. It also facilitates the accessibility of knowledge and research contribution among them. This paper aims at revealing some of the outmost features of ISC databases, in order to give a fairly clear view of what it is and what are its products. The paper consists of three major parts. After an introduction about the Islamic World Science Citation Center, the paper deals with major tools and products of ISC. In the third part ISCs' journal Submission system is presented as an automatic means, by which users can upload journals' papers into the respected databases. Some complementary remarks have been made regarding the current state of ISC and its future plans.

    Modern bibliographic databases provide the basis for scientific research and its evaluation. While their content and structure differ substantially, there exist only informal notions on their reliability. Here we compare the topological consistency of citation networks extracted from six popular bibliographic databases including Web of Science, CiteSeer and arXiv.org. The networks are assessed through a rich set of local and global graph statistics. We first reveal statistically significant inconsistencies between some of the databases with respect to individual statistics. For example, the introduced field bow-tie decomposition of DBLP Computer Science Bibliography substantially differs from the rest due to the coverage of the database, while the citation information within arXiv.org is the most exhaustive. Finally, we compare the databases over multiple graph statistics using the critical difference diagram. The citation topology of DBLP Computer Science Bibliography is the least consistent with the rest, w...

    Full Text Available   The present paper examines the links between self-citation and authors’ co-incidence with impact factors of economic journals indexed in ISC. It is essentially a scientometric research employing citation analysis and literature survey. Data was collected by querying ISC and leafing through the journals studied. Self-citation, authors’ co-incidence and impact factor of the journal studied formed the variables. Correlation analysis indicated that there is a significance between authors’ self-citations and co-incidence with impact factor of the journals studied. Significance was also found between authors’ co-incidence and self-citation of the journals studied.

    A bibliometric analysis was completed of highly cited occupational therapy literature and authors published from 1991 to 2014 and accessible in the Science Citation Index Expanded (SCI-Expanded) and Social Sciences Citation Index (SSCI) databases. Data were obtained from the SCI-Expanded and SSCI. Articles referenced >100 times were categorized as highly cited articles (HCA). Of 6,486 articles found, 31 were categorized as HCA. The American Journal of Occupational Therapy published the largest number of HCA (n = 8; 26%). The 31 HCA were distributed across seven countries: United States (20 articles), Canada (3), United Kingdom (3), Australia (2), the Netherlands (1), New Zealand (1), and Sweden (1). The three authors with the highest Y-index were S. J. Page, F. Clark, and W. Dunn. A latency period of 4 to 5 yr post-publication appears to be needed for a journal article to gain citations.

    To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Bibliometric analysis. Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. To identify health science journals, results were refined using Ulrich's database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Resulting citations were thematically coded, and descriptive statistics were calculated. 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n = 648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia.

    To analyze the 2007 citation count of articles published by the Croatian Medical Journal in 2005-2006 based on data from the Web of Science, Scopus, and Google Scholar. Web of Science and Scopus were searched for the articles published in 2005-2006. As all articles returned by Scopus were included in Web of Science, the latter list was the sample for further analysis. Total citation counts for each article on the list were retrieved from Web of Science, Scopus, and Google Scholar. The overlap and unique citations were compared and analyzed. Proportions were compared using chi(2)-test. Google Scholar returned the greatest proportion of articles with citations (45%), followed by Scopus (42%), and Web of Science (38%). Almost a half (49%) of articles had no citations and 11% had an equal number of identical citations in all 3 databases. The greatest overlap was found between Web of Science and Scopus (54%), followed by Scopus and Google Scholar (51%), and Web of Science and Google Scholar (44%). The greatest number of unique citations was found by Google Scholar (n=86). The majority of these citations (64%) came from journals, followed by books and PhD theses. Approximately 55% of all citing documents were full-text resources in open access. The language of citing documents was mostly English, but as many as 25 citing documents (29%) were in Chinese. Google Scholar shares a total of 42% citations returned by two others, more influential, bibliographic resources. The list of unique citations in Google Scholar is predominantly journal based, but these journals are mainly of local character. Citations received by internationally recognized medical journals are crucial for increasing the visibility of small medical journals but Google Scholar may serve as an alternative bibliometric tool for an orientational citation insight.

    2015-01-01

    Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.

    The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. PMID:2655785

    A citation analysis of biomedical and health sciences journals was conducted based on their enlistment in journal databases to identify the factors contributing to the citation metrics. Among the 1,219 academic journals managed by the National Center for Medical Information and Knowledge at the Korea Centers for Disease Control and Prevention, 556 journals were included for analysis as of July 2016. The characteristics of the journals include history years, publication media, language, open-access policy as well as the status enlisted in international and domestic databases, such as Science Citation Index (SCI), Scopus, Medline, PubMed Central, Embase, and Korea Citation Index (KCI). Six bibliometric measures were collected from SCI, Scopus, and KCI as of 2015, the most recent disclosure year. Analyses of group differences and influential factors were conducted using t-tests, Mann-Whitney tests, and multiple regression. Journal characteristics, such as history years, publication media, and open-access policy, were not significant factors influencing global or domestical citation of the journals. However, global citations were higher for SCI and Medline enlisted journals than for their counterparts. Among KCI journals, the KCI impact factors of journals published in English only were lower. Efforts by journals to be enlisted in international databases, especially in SCI and Medline, are critical to enhance their global circulation. However, articles published in English only hinder the use of domestic researchers. Different strategies are required for enhancing international and domestic readerships.

    The diabetes educator/researcher is faced with a proliferation of diabetes articles in various journals, both online and in print. Keeping track of cited references and remembering how to cite the references in text and the bibliography can be a daunting task for the new researcher and a tedious task for the experienced researcher. The challenge is to find and use a technology, such as bibliographic database software (BDS), which can help to manage this information overload. This article focuses on the use of BDS for the diabetes educator who is undertaking research. BDS can help researchers access and organize literature and make literature searches more efficient and less time consuming. Moreover, the use of such programs tends to reduce errors associated with the complexity of bibliographic citations and can increase the productivity of scholarly publications. The purpose of this article is to provide an overview of BDS currently available, describe how it can be used to aid researchers in their work, and highlight the features of different programs. It is important for diabetes educators and researchers to explore the many benefits of such BDS programs and consider their use to enhance the accuracy and efficiency of accessing and citing references of their research work and publications. Armed with this knowledge, researchers will be able to make informed decisions about selecting BDS which will meet their usage requirements.

    Researchers turn to citation tracking to find the most influential articles for a particular topic and to see how often their own published papers are cited. For years researchers looking for this type of information had only one resource to consult: the Web of Science from Thomson Scientific. In 2004 two competitors emerged--Scopus from Elsevier and Google Scholar from Google. The research reported here uses citation analysis in an observational study examining these three databases; comparing citation counts for articles from two disciplines (oncology and condensed matter physics) and two years (1993 and 2003) to test the hypothesis that the different scholarly publication coverage provided by the three search tools will lead to different citation counts from each. Eleven journal titles with varying impact factors were selected from each discipline (oncology and condensed matter physics) using the Journal Citation Reports (JCR). All articles published in the selected titles were retrieved for the years 1993 and 2003, and a stratified random sample of articles was chosen, resulting in four sets of articles. During the week of November 7-12, 2005, the citation counts for each research article were extracted from the three sources. The actual citing references for a subset of the articles published in 2003 were also gathered from each of the three sources. For oncology 1993 Web of Science returned the highest average number of citations, 45.3. Scopus returned the highest average number of citations (8.9) for oncology 2003. Web of Science returned the highest number of citations for condensed matter physics 1993 and 2003 (22.5 and 3.9 respectively). The data showed a significant difference in the mean citation rates between all pairs of resources except between Google Scholar and Scopus for condensed matter physics 2003. For articles published in 2003 Google Scholar returned the largest amount of unique citing material for oncology and Web of Science returned the

  3. Publication boost in Web of Science journals and its effect on citation distributions

    Šubelj, Lovro

    2016-01-01

    In this paper we show that the dramatic increase in the number of research articles indexed in the Web of Science database impacts the commonly observed distributions of citations within these articles. First, we document that the growing number of physics articles in recent years is due to existing journals publishing more and more papers rather than more new journals coming into being as it happens in computer science. And second, even though the references from the more recent papers generally cover a longer time span, the newer papers are cited more frequently than the older ones if the uneven paper growth is not corrected for. Nevertheless, despite this change in the distribution of citations, the citation behavior of scientists does not seem to have changed.

    In the scientometric, the main criterion in determining the scientific position and ranking of the scientific centers, particularly the universities, is the rate of scientific production and innovation, and in all participations in the global scientific development. One of the subjects more involved in repeatedly dealt with science and technology and effective on the improvement of health is medical science fields. In this research using scientometric and citation analysis, we studied the rate of scientific productions in the field of community medicine, which is the numbers of articles published and indexed in ISI database from 2000 to 2010. This study is scientometric using the survey and analytical citation. The study samples included all of the articles in the ISI database from 2000 to 2010. For the data collection, the advance method of searching was used at the ISI database. The ISI analyses software and descriptive statistics were used for data analysis. Results showed that among the five top universities in producing documents, Tehran University of Medical Sciences with 88 (22.22%) documents are allocated to the first rank of scientific products. M. Askarian with 36 (90/9%) published documents; most of the scientific outputs in Community medicine, in the international arena is the most active author in this field. In collaboration with other writers, Iranian departments of Community Medicine with 27 published articles have the greatest participation with scholars of English authors. In the process of scientific outputs, the results showed that the scientific process was in its lowest in the years 2000 to 2004, and while the department of Community medicine in 2009 allocated most of the production process to itself. Iranian Journal of Public Health and Saudi Medical Journal each of them had 16 articles which had most participation rate in the publishing of community medicine's department. On the type of carrier, community medicine's department by

    Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of 'anaesthesiology'. Journals related to 'anaesthesiology' in the Science Citation Index-Expanded database of 'Thomson Reuter Web of Science' were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing 'IS=ISSN number' to identify publications in the journal. By typing 'IS=ISSN number AND CU=Turkey', Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, 'SU=anesthesiology' was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. From 1975 to the early 2000s Turkey was 20th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18th place. Its mean citation number has been 4.64, and it remains the 2nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. The mean citation

    Citation metrics and h indices differ using different bibliometric databases. We compiled the number of publications, number of citations, h index and year since the first publication from 340 soil researchers from all over the world. On average, Google Scholar has the highest h index, number of publications and citations per researcher, and the Web of Science the lowest. The number of papers in Google Scholar is on average 2.3 times higher and the number of citations is 1.9 times higher compared to the data in the Web of Science. Scopus metrics are slightly higher than that of the Web of Science. The h index in Google Scholar is on average 1.4 times larger than Web of Science, and the h index in Scopus is on average 1.1 times larger than Web of Science. Over time, the metrics increase in all three databases but fastest in Google Scholar. The h index of an individual soil scientist is about 0.7 times the number of years since his/her first publication. There is a large difference between the number of citations, number of publications and the h index using the three databases. From this analysis it can be concluded that the choice of the database affects widely-used citation and evaluation metrics but that bibliometric transfer functions exist to relate the metrics from these three databases. We also investigated the relationship between journal's impact factor and Google Scholar's h5-index. The h5-index is a better measure of a journal's citation than the 2 or 5 year window impact factor.

    The total number of times a paper is cited, also known as the impact factor (IF) of a medical journal, is widely implied in evaluating the quality of a research paper. We evaluated the citation index data as an IF of Korean J Pediatr in Korean Medical Citation Index (KoMCI) and JCI of Web of Science. We calculated the IF of Korean J Pediatr at KoMCI supervised by Korean Association of Medical Journal Editors. And we estimated the IF of Korean J Pediatr by the JCI of Web of Science although it was never officially reported. The IF of Korean J Pediatr on KoMCI has increased from 0.100 in the year 2000, to 0.205 in 2008, and 0.326 in 2009. Although the IF of Korean J Pediatr was 0.006 in 2005, 0.018 in 2006, 0.028 in 2008, 0.066 in 2009, and 0.018 in 2010 according to the JCI of Web of Science, the number of citations are steadily increasing. Understanding and realizing the current status will be a stepping stone for further improvement. The next objective of the Korean J Pediatr is to become registered in the SCI or SCIE. Increasing the IF according to the JCI of Web of Science is crucial in order to achieve this goal.

    INTRODUCTION: Citation indexes are produced by counting de-contextualised citations, which result from the transformation of references into citations, generating two different objects -two different signs-. This causes an ambiguity of both signs which is relevant for citation indexes and for science evaluation. METHODOLOGY: Two methods were used: 1) Qualitatively: It is performed a semiotic analysis in order to distinguish between bibliographic references and citations in terms of electronic...

  11. Citation Analysis using the Medline Database at the Web of Knowledge: Searching "Times Cited" with Medical Subject Headings (MeSH)

    2012-01-01

    Citation analysis of documents retrieved from the Medline database (at the Web of Knowledge) has been possible only on a case-by-case basis. A technique is here developed for citation analysis in batch mode using both Medical Subject Headings (MeSH) at the Web of Knowledge and the Science Citation Index at the Web of Science. This freeware routine is applied to the case of "Brugada Syndrome," a specific disease and field of research (since 1992). The journals containing these publications are attributed to Web-of-Science Categories other than "Cardiac and Cardiovascular Systems"), perhaps because of the possibility of genetic testing for this syndrome in the clinic. With this routine, all the instruments available for citation analysis can be used on the basis of MeSH terms.

  12. The rate of growth in scientific publication and the decline in coverage provided by Science Citation Index.

    Science.gov (United States)

    Larsen, Peder Olesen; von Ins, Markus

    2010-09-01

    The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

    2015-01-01

    In this study, we present an analysis of data citation practices in full text research articles and their corresponding supplementary data files, made available in the Open Access set of articles from Europe PubMed Central. Our aim is to investigate whether supplementary data files should be considered as a source of information for integrating the literature with biomolecular databases. Using text-mining methods to identify and extract a variety of core biological database accession numbers, we found that the supplemental data files contain many more database citations than the body of the article, and that those citations often take the form of a relatively small number of articles citing large collections of accession numbers in text-based files. Moreover, citation of value-added databases derived from submission databases (such as Pfam, UniProt or Ensembl) is common, demonstrating the reuse of these resources as datasets in themselves. All the database accession numbers extracted from the supplementary data are publicly accessible from http://dx.doi.org/10.5281/zenodo.11771. Our study suggests that supplementary data should be considered when linking articles with data, in curation pipelines, and in information retrieval tasks in order to make full use of the entire research article. These observations highlight the need to improve the management of supplemental data in general, in order to make this information more discoverable and useful.

  14. Citation analysis in health care sciences. Innovative investigation or seductive pseudo-science?

    Science.gov (United States)

    Rigby, M

    2014-01-01

    Citations of scientific papers in health care have become a subject of interest, as in any scientific sector. However, such a metric, while useful in a simple way, can become subject to too much credibility, and therefore to advanced analyses which are not soundly grounded even if methodologically valid. The objective was to contextualise citation indices in health care science, juxtaposed with a parallel analytic paper. The literature was reviewed and set against the objectives of metrics of literature and of researchers. The strengths and weaknesses of citation indices in the health sector were identified, with practical examples of perverse effects, and compared with the core objectives of health care development. Citation indices in health care science have a value, but this is limited to giving a broad overview. Other measures of effectiveness, including impact on education, on health care development, and on stimulation of applied developments, are needed rather than spuriously scientific advanced analyses of citation counts.

    There are often differences in a publication's citation count, depending on the database accessed. Here, aspects of citation counts for medical physics and biomedical engineering papers are studied using papers published in the journal Australasian physical and engineering sciences in medicine. Comparison is made between the Web of Science, Scopus, and Google Scholar. Papers are categorised into subject matter, and citation trends are examined. It is shown that review papers as a group tend to receive more citations on average; however the highest cited individual papers are more likely to be research papers.

    Full Text Available The present study determines the co-authorship factor in the Iranian scientific output between 2000 and 2006 as reflected in the science, social science art and humanities citation indexes made available through the Web of Science database. Webometric indicators were used. The data were extracted in plain text from WOS, analyzed using HistCite software and counted in MS Office Excel program. Of the Total of 25320 documents indexed, 24480 documents were in Science Citation Index, 783 in Social Citation Index and 57 in Art and Humanities index. The findings indicated that co-authorship factor in the period studied had been on the rise. The highest participation rate belonged to the documents with two or three authors. General coauthorship factor was 0.59. The year 2006 had the highest coauthorship factor (0.62 while the year 2000 had the least (0.55. Bradford and Lotka laws were applied to the data sets. The Lotka’s Law only held true for the science citation index. The Bradford’s Law, however, held true for all indexes. In all citation indexes, the United States with 1865 documents (7.38 had the highest degree of coauthorship in Iranian scientific output.

    CERN Document Server

    Leydesdorff, Loet

    2012-01-01

    In 2011, Thomson-Reuters introduced the Book Citation Index (BCI) as part of the Science Citation Index (SCI). The interface of the Web of Science version 5 enables users to search for both "Books" and "Book Chapters" as new categories. Books and book chapters, however, were always among the cited references, and book chapters have been included in the database since 2005. We explore the two categories with both BCI and SCI, and in the sister databases for the social sciences (SoSCI) and the arts and humanities (A&HCI). Book chapters in edited volumes can be highly cited. Books contain many citing references, but are relatively less cited. We suggest that this may find its origin in the slower circulation of books then of journal articles. It is possible to distinguish scientometrically between monographs and edited volumes among the "Books". Monographs may be underrated in terms of citation impact or overrated using publication performance indicators because individual chapters are counted separately as ...

    Full Text Available This article outlines a simple approach to characterizing the level of access to the scholarly journal literature in the physical sciences and engineering offered by a research library, particularly within the Canadian university system. The method utilizes the “Journal Citation Reports” (JCR database to produce lists of journals, ranked based on total citations, in the subject areas of interest. Details of the approach are illustrated using data from the University of Guelph. The examples cover chemistry, physics, mathematics and statistics, as well as engineering. In assessing the level of access both the Library’s current journal subscriptions and backfiles are considered. To gain greater perspective, data from both 2003 and 2008 is analyzed. In addition, the number of document delivery requests, received from University of Guelph Library users in recent years, are also reviewed. The approach taken in characterizing access to the journal literature is found to be simple and easy to implement, but time consuming. The University of Guelph Library is shown to provide excellent access to the current journal literature in the subject areas examined. Access to the historical literature in those areas is also strong. In making these assessments, a broad and comprehensive array of journals is considered in each case. Document delivery traffic (i.e. Guelph requests is found to have decreased markedly in recent years. This is attributed, at least in part, to improving access to the scholarly literature. For the University of Guelph, collection assessment is an ongoing process that must balance the needs of a diverse group of users. The results of analyses of the kind discussed in this article can be of practical significance and value to that process.

    2012-01-01

    Vision Science is considered to be a quite developed discipline in Nepal, with much research currently in progress. Though the results of these endeavors are published in scientific journals, formal citation analyses have not been performed on works contributed by Nepalese vision scientists. To study Nepal's contribution to vision science literature in the database "Web of Science". The primary data source of this paper was Web of Science, a citation database of Thomas Reuters. All bibliometric analyses were performed with the help of Web of Science analysis service. In the current database of vision science literature, Nepalese authors contributed 112 publications to Web of Science, 95 of which were original articles. Pokharel GP had the highest number of citations among contributing authors of Nepal. Hennig A contributed the highest number of article as a first author. The Nepal Eye Hospital contributed the highest number of articles as an institution to the field of Vision Science. Currently, only two journals from Nepal including Journal of Nepal Medical Association (JAMA) are indexed in the Web of Science database (Sieving, 2012). To evaluate the total productivity of vision science literature from Nepal, total publication counts from national journals and articles indexed in other databases such as PubMed and Scopus must also be considered. © NEPjOPH.

    1997-10-18

    MEDICINA CLINICA has been indexed in the Science Citation Index (SCI) database since 1992, listed in the category Medicine, General & Internal, and its impact factor in 1993 was 0.909. Two years as source journal in the SCI database provide enough information to assess its contribution to the international scientific scenario. Publications of Spanish authors in MEDICINA CLINICA during 1992 and 1993 were retrieved from the SCI. Document types, geographic distribution, institutional sectors, subjects and most productive centers were analyzed. All documents retrieved from the SCI were compared manually with those published in the journal itself. Citations received until November 1996 were collected and reference patterns assessed. MEDICINA CLINICA was in the upper third of the list of journals of its category ranked by their impact factor. As other general medical journals, it was characterized by the publication of a high number of letters to the editor (48% of documents) and of articles susceptible of being classified in other disciplines according to their contents. Main topics of documents authored by Spanish authors included: Infectious Diseases (15%), Pharmacy/Pharmacology (8.8%), Cancer/Oncology (7.2%), Cardiovascular System (4.9%), Epidemiology/Public Health (4.5%), Endocrinology/Metabolism (4%) and Neurosciences/Neurology (4%). Only 32% of studies corresponding to citable items had been carried out in Barcelona, the city in which the journal is published, 19.5% in Madrid, and almost 9% in Andalucia. Around 66% of articles and only 25% of letters have received at least one citation, with a mean number of citations of 2.83 for articles and 1.3 for letters. Self-citations from other documents published in the same journal were high (77.8% for articles) as compared with citations received from other international SCI journals. Reference patterns found in MEDICINA CLINICA were similar to those of high-ranking journals of the same category. The comparison of

    2013-02-01

    This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

    The purpose of this study was to identify the top-cited articles published in environmental science journals listed in Journal Citation Reports (JCR). The Web of Science database was used to retrieve the top-cited articles having 500 or more total citations from their publication to 2010. The articles were analyzed with regard to institution and country of origin with five indicators including total number of top-cited articles, as well as independent, collaborative, first author, and corresponding author articles. Article life was also investigated for history of impact of articles. Results showed that 88 articles were cited more than 500 times. These articles appeared in 26 different journals, with 28% of all top-cited articles in Environmental Science & Technology, followed by Water Resources Research. The top-cited articles published since 1971 to 2002 were from 17 countries. The USA published the most of the articles and was ranked on top among the five indicators. The U.S. Geological Survey was the most productive institution while, the Brunel University, UK published the most inter-institutionally collaborative and corresponding author articles under environmental science category.

    2009-01-01

    In the scientific research community, plagiarism and covert multiple publications of the same data are considered unacceptable because they undermine the public confidence in the scientific integrity. Yet, little has been done to help authors and editors to identify highly similar citations, which sometimes may represent cases of unethical duplication. For this reason, we have made available Déjà vu, a publicly available database of highly similar Medline citations identified by the text similarity search engine eTBLAST. Following manual verification, highly similar citation pairs are classified into various categories ranging from duplicates with different authors to sanctioned duplicates. Déjà vu records also contain user-provided commentary and supporting information to substantiate each document's categorization. Déjà vu and eTBLAST are available to authors, editors, reviewers, ethicists and sociologists to study, intercept, annotate and deter questionable publication practices. These tools are part of a sustained effort to enhance the quality of Medline as 'the' biomedical corpus. The Déjà vu database is freely accessible at http://spore.swmed.edu/dejavu. The tool eTBLAST is also freely available at http://etblast.org.

    2013-06-01

    Full Text Available Citing literature is a very important activity for scholars in writing articles. Many publishers and libraries build citation databases and provide citation reports on scholarly journals. Cited-by linking is a service representing what an article cites and how many times it cites a specific article within a journal database. Recently, information services based on DOIs (Digital Object Identifiers have been increasing in number. CrossRef, a non-profit organization for the DOI registration agency, maintains the DOI system and provides the cited-by linking service. Recently, the number of Korean journals adopting DOI is also rapidly increasing. The Korea Institute of Science and Technology Information (KISTI supports Korean learned societies in DOI related activities in collaboration with CrossRef. This study analyzes cited patterns of Korean DOI journal articles using CrossRef's cited-by linking data and a Korean journal citation database. This analysis has been performed in terms of publication country and the language of journals citing Korean journal articles. The results show that DOI, SCI(E (Science Citation Index (Expanded, and English journals are more likely to be cited internationally.

    2017-09-01

    Full Text Available The complexity of biological systems requires use of a variety of experimental methods with ever increasing sophistication to probe various cellular processes at molecular and atomic resolution. The availability of technologies for determining nucleic acid sequences of genes and atomic resolution structures of biomolecules prompted development of major biological databases like GenBank and PDB almost four decades ago. India was one of the few countries to realize early, the utility of such databases for progress in modern biology/biotechnology. Department of Biotechnology (DBT, India established Biotechnology Information System (BTIS network in late eighties. Starting with the genome sequencing revolution at the turn of the century, application of high-throughput sequencing technologies in biology and medicine for analysis of genomes, transcriptomes, epigenomes and microbiomes have generated massive volumes of sequence data. BTIS network has not only provided state of the art computational infrastructure to research institutes and universities for utilizing various biological databases developed abroad in their research, it has also actively promoted research and development (R&D projects in Bioinformatics to develop a variety of biological databases in diverse areas. It is encouraging to note that, a large number of biological databases or data driven software tools developed in India, have been published in leading peer reviewed international journals like Nucleic Acids Research, Bioinformatics, Database, BMC, PLoS and NPG series publication. Some of these databases are not only unique, they are also highly accessed as reflected in number of citations. Apart from databases developed by individual research groups, BTIS has initiated consortium projects to develop major India centric databases on Mycobacterium tuberculosis, Rice and Mango, which can potentially have practical applications in health and agriculture. Many of these biological

    Full Text Available We would like to verify the correlation among various citation indicators of 62 Korean scientific journals listed in the Web of Science (WoS and Scopus. From a total of 85 Korean journals listed in both WoS as of January 2013, and 132 journals listed in Scopus as of 2011, 62 Korean journals listed in both citation indices were selected for analysis. Citation index indicators selected for analysis include impact factor (IF, 5-year impact factor (5yrIF, Eigenfactor score (EF, article influence score (AIS (list of WoS indicators, SCImago journal rank (SJR, h-index, and impact index (ImIndex (list of Scopus indicators. It took an average of eight years for a newly founded journal to be listed in Science Citation Index Expanded (SCIE. Since the IF, ImIndex, and AIS values failed to exceed 1.0, Korean journals’ popularity and prestige were confirmed to be minimal. Analyzed journals that were written in English exhibited higher SJR and h-index values than ones written in Korean. WoS’ IF exhibited a correlation with WoS’ 5yrIF, EF, AIS, and Scopus’ SJR, h-index, and ImIndex. Since the ‘popularity and prestige of Korean journals’ have been confirmed to be minimal, steps must be taken to improve this status. Popularity-based indicators have been shown to strongly correlate with prestige-based indicators in Korean science journals. Therefore, there must be a strategic approach taken to improve IF values.

    2014-01-01

    Do citations accumulate too slowly in the social sciences to be used to assess the quality of recent articles? I investigate whether this is the case using citation data for all articles in economics and political science published in 2006 and indexed in the Web of Science. I find that citations in the first two years after publication explain more than half of the variation in cumulative citations received over a longer period. Journal impact factors improve the correlation between the predicted and actual future ranks of journal articles when using citation data from 2006 alone but the effect declines sharply thereafter. Finally, more than half of the papers in the top 20% in 2012 were already in the top 20% in the year of publication (2006).

    Who today are the most highly cited psychologists listed in the Web of Science? This paper reports answers to this question by using the Science Citation Index Expanded to find out. This index covers over 280,350 documents in the Psychology category of the Web of Science from 1900 to 2013 and lists the most highly cited papers published between 1927 and 2012. For example, in 2013, an article published by Jacob Cohen in 1992 obtained (1) the highest ranking with 1,068 citations, (2) the highest for total citations per year, and (3) was ranked 3rd for the total number of citations since publication by 2013. New technology thus provides a seismic shift in the ways that we can obtain and analyse data like these. Indeed, the results for the top 10 articles indicate that practical and methodological papers now receive more citations than the more theoretical papers usually found in earlier surveys. © 2015 The British Psychological Society.

    The book is written paralelly in Serbian and English. The presence of works of Serbian astronomers and works in astronomical journals published by other Serbian scientists, in Science Citation Index within the period from 1945 up to the end of 2000, has been analyzed. Also is presented the list of 38 papers which had some influence on the development of astronomy in the twentieth century. A review of the development of astronomy in Serbia in the last century is given as well. Particular attention is payed to the Astronomical Observatory, the principal astronomical institution in Serbia, where it is one of the oldest scientific organizations and the only autonomous astronomical institute. Its past development forms an important part of the history of science and culture in these regions. In the book is also considered and the history of the university teaching of astronomy in Serbia after the second world war. First of all the development of the Chair of Astronomy at the Faculty of Mathematics in Belgrade, but also the teaching of astronomy at University in Novi Sad, Ni and Kragujevac is discussed. In addition to professional Astronomy, well developed in Serbia is also the amateur Astronomy. In the review is first of all included the largest and the oldest organization of amateur-astronomers in Serbia, founded in 1934. Besides, here are the Astronomical Society "Novi Sad", ADNOS and Research Station "Petnica". In Valjevo, within the framework of the Society of researchers "Vladimir Mandic - Manda", there is active also the Astronomical Group. In Kragujevac, on the roof of the Institute of Physics of the Faculty of Sciences, there is the "Belerofont" Observatory. In Ni, at the close of the sixties and the start of the seventies, there was operating a branch of the Astronomical Society "Rudjer Bokovic", while at the Faculty of Philosophy there existed in the period 1976-1980 the "Astro-Geophysical Society". In the year 1996 there was founded Astronomical Society

  2. Currencies of Science: discussing disciplinary “exchange rates” for citations and Mendeley readership

    Energy Technology Data Exchange (ETDEWEB)

    Costas, R.; Perianes-Rodriguez, A.; Ruiz-Castillo, J.

    2016-07-01

    In 1998 Garfield stated that “[t]he Mertonian description of normal science describes citations as the currency of science. Scientists make payments, in the form of citations, to their preceptors”. The idea of citations as a currency of science was also discussed by Wouters (1999) who suggested that the “role of the citation might also be compared with that of money, especially if the evaluative use of scientometrics is taken into account. Whenever the value of an article is expressed in its citation frequency, the citation is probably the most important unit of a ‘currency of science’”. Thus, citations have been seen as currency able to reward scientists for their work and scientific merit, being an integral part, together with authorship and acknowledgements, of the so-called “reward triangle” (Cronin & Weaver, 1995)2. This role of citations as main currency in evaluative scientometrics has gone unchallenged until recently. The emergence of new ways of measuring the reception of scientific publications by different audiences in the form of the so-called “altmetrics” (Haustein, et al. 2015a; Priem, et al. 2010) probably represents the most important attempt of expanding the system of currencies of science. However, research on altmetrics suggest that there are critical differences with citations: in coverage (Thelwall, et al. 2013), main characteristics (Haustein, et al., 2015), correlations (Costas, et al. 2015b; Haustein, et al. 2014), and interpretation (Haustein et al., 2016). These results essentially highlight the limited potential of most of these metrics as realistic alternatives to citations. (Author)

    2011-03-01

    The Korean Journal of Internal Medicine (KJIM) is the international journal published in English by the Korean Association of Internal Medicine. To understand the position of the journal in three different databases, the citation indicators were elucidated. From databases such as Korean Medical Citation Index (KoMCI), Web of Science, and Scopus, citation indicators such as the impact factor, SCImago journal rank (SJR), or Hirsch Index were calculated according to the year and the results were drawn. The KJIM 2010 impact factor increased to 0.623 in Web of Science. That of year 2009 in KoMCI was a 0.149. The 2009 SJR in Scopus was 0.073, with a ranking of 27/72 (37.5%) in the category of internal medicine and 414/1,618 (25.6%) in the category of medicine, miscellaneous. The Hirsch Index from KoMCI, Web of Science and Scopus were 5, 14, and 16, respectively. The KJIM is now cited more by international researchers than Korean researchers, indicating that the content of the journal is now valued at the international level.

    Neurological sciences form a multidisciplinary field that produces a wide range of scientific journals. The aim of this study was to perform a scientometric analysis of neurological science journals in the 2006 Journal Citation Reports-Science Citation Index (JCR-SCI) edition. We study the three areas dedicated to neurological sciences (Neurosciences, Clinical Neurology and Neuroimaging) in the 2006 JCR-SCI edition. Bibliometric indicators used are: journals, articles, citations, impact factor (IF), immediacy index, half life and journals with the greatest IF in each specialty. We also perform a special analysis of Spanish neurological journals in JCR-SCI. In the area of Neurosciences we find a total of 200 journals, 27.157 articles, 1.109.784 citations and an average IF of 2,446, the greatest IF belonging to Annu Rev Neurosci (28,533) and Nat Rev Neurosci (23,054); Spanish journals: Neurocirugia and Acta Esp Psiquiatr. The area of Clinical Neurology contains 147 journals, 18.114 articles, 540.364 citations and an average IF of 1,848, the greatest IF belonging to Lancet Neurol (9,479) and Ann Neurol (8,051); Spanish journals: Neurologia and Rev Neurol. The area of Neuroimaging contains 13 journals, 1.747 articles, 49.210 citations and an average IF of 1,298, the greatest IF belonging to Neuroimage (5,559) and Hum Brain Mapp (4,888). We found out a broad representation of neurological journals from the 6,166 journals included in the 2006 JCR-SCI edition. Bibliometric characteristics differ in accordance to the clinical (Clinical Neurology) or experimental (Neurosciences) nature of the area. Even though bibliometric indicators for the four Spanish neurological journals have gradually improve over the previous 5 years, they are still proportionally ranked low in JCR-SCI. Due to significant limitations observed in the IF, we suggest conducting its analysis from a multidimensional bibliometric perspective, and always within its contextual research area.

    2008-01-01

    The authors of this article analyzed the differences in output when searching MEDLINE direct and MEDLINE via citation management software, EndNote X1, EndNote Web, and RefWorks. Several searches were performed on Ovid MEDLINE and PubMed directly. These searches were compared against the same searches conducted in Ovid MEDLINE and PubMed using the search features in EndNote X1, EndNote Web, and RefWorks. Findings indicated that for in-depth research users, should search the databases directly rather than through the citation management software interface. The search results indicated it would be appropriate to search databases via citation management software for citation verification tasks and for cursory keyword searching.

    We used bibliometric analysis methodology in the expanded Science Citation Index to identify highly-cited electrocardiogram (ECG)-related articles with total citations (TC2012) exceeding 100 from the publication year to 2012. Web of Science search tools were used to identify the highly-cited articles. The aspects analyzed for highly cited publications included effect of time on citation analysis, journals and Web of Science categories, number of authors per publication, originating institutions and countries, total citation and total citation per year life cycles of articles (C2012) and research hotspots. Results showed that a total of 467 electrocardiogram-related publications were regarded as the highly-cited publications. TC2012 ranged from 101 to 2879, with 215 as the average number of citations. No highly-cited publications have emerged yet during the first two years of the present 2010 Decade. All 11 countries and institutions originating highly-cited ECG-related publications were developed countries, USA in 9 of them. Four subject categories were identified as hotspots by total citations TC2012 and C2012: atrial fibrillation, long QT syndrome, angina and myocardial infarction, and risk factor analysis and health evaluation.

    Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

  9. World citation and collaboration networks: uncovering the role of geography in science

    CERN Document Server

    Pan, Raj Kumar; Fortunato, Santo

    2012-01-01

    Modern information and communication technologies, especially the Internet, have diminished the role of spatial distances and territorial boundaries. This has enabled scientists for closer collaboration and internationalization. Nevertheless, geography remains an important factor affecting the dynamics of science. Hence, assessing the influence of spatial proximity between scientists is crucial to promote efficient collaboration strategies and, ultimately, to improve the quality of science. Here we present a systematic analysis of citation and collaboration streams between cities and countries. By assigning papers to the geographic locations of their authors' affiliations, we construct weighted networks of citations and collaborations. The citation flows as well as the collaboration strengths between cities decrease with the distance between them and follow gravity laws with exponents close to 1. Moreover, for a given number of authors, the diversity of affiliations increases the number of citations, especial...

    2017-04-01

    Full Text Available Introduction: Open access refers to scientific literature available free of charge and free of copyright restrictions and licensing for its reuse. An increase in the total number of citations received by articles available in open access in relation to those of restricted, pay-walled access is expected, according to the Open Access Citation Advantage hypothesis. Objective: Assess the possible citation advantages and mentions on the social web that open access can offer to the Information Science area. Methodology: Bibliometric and altmetric indicators were analyzed in two journals: Journal of the American Society for Information Science and Scientometrics. Data collection was conducted in the Web of Science, Google Scholar, Altmetric.com and Mendeley. Results: The results indicated that for both journals, open access offers an advantage in the number of citations received by articles. It was also demonstrated that the advantage is maintained over time. Conclusions: This research confirmed the hypothesis of an Open Access Citation Advantage for the journals analyzed in the area of Information Science. This pattern was also observed for the altmetric data.

    Full Text Available Objective – To determine whether three competing citation tracking services result in differing citation counts for a known set of articles, and to assess the extent of any differences.Design – Citation analysis, observational study.Setting – Three citation tracking databases: Google Scholar, Scopus and Web of Science. Subjects – Citations from eleven journals each from the disciplines of oncology and condensed matter physics for the years 1993 and 2003.Methods – The researchers selected eleven journals each from the list of journals from Journal Citation Reports 2004 for the categories “Oncology” and “Condensed Matter Physics” using a systematic sampling technique to ensure journals with vary ingimpact factors were included. All references from these 22 journals were retrieved for the years 1993 and 2003 by searching three databases: Web of Science, INSPEC, and PubMed. Only research articles were included for the purpose of the study. From these, a stratified random sample was created to proportionally represent the content of each journal (oncology 1993: 234 references, 2003: 259 references; condensed matter physics 1993: 358 references, 2003: 364 references. In November of 2005, citations counts were obtained for all articles from Web of Science, Scopus and GoogleScholar. Due to the small sample size and skewed distribution of data, non‐parametric tests were conducted to determine whether significant differences existed between sets.Main Results – For 1993, mean citation counts were highest in Web of Science for both oncology (mean = 45.3, SD = 77.4 and condensed matter physics (mean = 22.5, SD= 32.5. For 2003, mean citation counts were higher in Scopus for oncology (mean = 8.9,SD = 12.0, and in Web of Science for condensed matter physics (mean = 3.0, SD =4.0. There was not enough data for the set of citations from Scopus for condensed matter physics for 1993 and it was therefore excluded from analysis. A Friedman test

    Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

    2012-08-01

    The 126 most frequently cited articles published in the adsorption field between 1900 and 2011 were identified and characterized using the Science Citation Index (Expanded). The data analyzed cover a range of publication years, journals, Web of Science categories, authors, institutions, countries/territories, life citation cycle curves, and characteristics of frequently cited articles. The 126 most-frequently-cited articles were each cited an average of 1014 times, ranging from 502 to 9922 citations per article from 1918 to 2006; 80% of these articles were published after 1970. Fifty-five journals were represented, led by the Journal of the American Chemical Society, and followed by Science and Nature. Three categories out of the 35 Web of Science categories constituted 60% of the citations. The three categories were: physical chemistry, multidisciplinary chemistry, and multidisciplinary sciences. Thirteen of the authors contributed three or more articles. Harvard University, the Massachusetts Institute of Technology, and the University of Washington led the list of 107 institutions, while the United States led the list of 17 countries/territories, comprising more than half of the articles. Collaboration among the top authors was a frequent occurrence, while inter-institutional collaboration and national collaboration was not obvious among the topmost articles. Moreover, the citation patterns as a function of time varied widely among the topmost articles. As evidenced by citation life cycles, the well known BET and Langmuir isotherms have received considerable attention during the study period, and will probably continue to be popular in the adsorption field. Some emerging hotspots are likely to receive particular attention in the near future; these include the new family of "M41S" materials, pseudo-second-order kinetic models, and the nudged elastic band method.

    The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases.

    Citations play an important role in medical and scientific databases by indicating the authoritative source of the data. Manual citation entry is tedious and prone to errors. We describe a method and make available computer scripts which automate the process of citation entry. We use an open citation project PERL module (PARSER) for parsing citation data that is then used to retrieve PubMed records to supply the (validated) reference. Our PERL scripts are available via a link in the web references section of this article.

    2014-01-01

    Solomon Hsiang is representative of a new generation in the geosciences community, whose work spans several disciplines, drawing on methods and concepts from far outside the traditional physical science domain in order to make progress on difficult questions at the intersection of natural science, social science, and public policy. Broadly speaking, by examining how humanity has responded to climate variability and change in the distant and recent past, Sol's research elucidates the question of how humanity may respond to a changing climate in the future. Combining large, independent sets of social science, meteorological, and climatological data and analyzing them with tools more common in microeconomics than natural science, Sol, still at an early stage of his career, has made critical contributions to an incipient revolution in our understanding of the sensitivity and adaptability of humans and their social arrangements to climate variability and change. Such insights will greatly improve the information base from which effective public policy is developed.

    2008-01-01

    Traditionally, the most commonly used source of bibliometric data is the Thomson ISI Web of Knowledge, in particular the (Social) Science Citation Index and the Journal Citation Reports, which provide the yearly Journal Impact Factors. This database used for the evaluation of researchers is not advantageous in the humanities, mainly because books, conference papers, and non-English journals, which are an important part of scientific activity, are not (well) covered. This paper presents the use of an alternative source of data, Google Scholar, and its benefits in calculating citation metrics in the humanities. Because of its broader range of data sources, the use of Google Scholar generally results in more comprehensive citation coverage in the humanities. This presentation compares and analyzes some international case studies with ISI Web of Knowledge and Google Scholar. The fields of economics, geography, social sciences, philosophy, and history are focused on to illustrate the differences of results between these two databases. To search for relevant publications in the Google Scholar database, the use of "Publish or Perish" and of CleanPoP, which the author developed to clean the results, are compared.

    Full Text Available This article analyzes motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations are good indicators for the societal impact or benefits of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging.org published between 01/01/2012 to 18/06/2014 were subjected to content analysis. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty‐one (22.68% of all cited journals were from the social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy‐five percent of all journals were referenced only once. The average age of articles cited at the time of citation was 5.8 years. Discussion and criticism were the two main categories of motivations. Overall, the study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact. A considerable number of citation motivations in blogs such as disputing a belief, suggesting policies, providing a solution to a problem, reacting to media, criticism and the like seemed to support gaining societal benefits. Societal benefits are considered as helping stimulate new approaches to social issues, or informing public debate and policymaking. Lower self‐citation (compared to some other altmetric measures such as tweets and the fact that blogging involves generating content (i.e. an intellectual process give them an advantage for altmetrics. However, limitations and contextual issues such as disciplinary differences and low uptake of altmetrics, in general, in scholarly communication should not be ignored when using blogs as a data source for altmetrics.

    Citation tracking is an important method to analyze the scientific impact of journal articles and can be done through Scopus (SC), Google Scholar (GS), or ISI web of knowledge (WOS). In the current study, we analyzed the citations to 2011-2012 articles of Iranian Journal of Basic Medical Sciences (IJBMS) in these three resources. The relevant data from SC, GS, and WOS official websites. Total number of citations, their overlap and unique citations of these three recourses were evaluated. WOS and SC covered 100% and GS covered 97% of the IJBMS items. Totally, 37 articles were cited at least once in one of the studied resources. Total number of citations were 20, 30, and 59 in WOS, SC, and GS respectively. Forty citations of GS, 6 citation of SC, and 2 citations of WOS were unique. Every scientific resource has its own inaccuracies in providing citation analysis information. Citation analysis studies are better to be done each year to correct any inaccuracy as soon as possible. IJBMS has gained considerable scientific attention from wide range of high impact journals and through citation tracking method; this visibility can be traced more thoroughly.

    Intensive research in the earth sciences over the past decades has created a tremendous wealth of literature, data, and material collections. So far, literature, data and sample collections have been separated. Information technology and the internet, in particular the new cyberinfrastructures for the earth sciences, offer ways to interlink literature, data and samples, creating the potential for new interpretations of the data and materials beyond the interpretation already published in the literature. To achieve this, technical, editorial and custodial issues need to be resolved. A key to this is the use of persistent identifiers for literature, data and sample collection objects. Past experience has shown that URLs are transient, but systems of persistent identifiers (e.g. handle.net, DOI, URN) already exist and can be used to reference these objects. The project `Publication and citation of scientific primary data' (STD-DOI) shows prototypically how these criteria can be met and implements a system for the publication of scientific data, which is open to the scientific community in any scientific field. This project uses persistent identifiers (DOI, handle.net and URN) to identify datasets available in a digital format. In addition, the data publications may be included into the catalogue of the German National Library of Science and Technology (TIB). Data at finer granularity are only identified by generic handle.net IDs, not by DOIs. Ideally, literature should already reference the materials used and the data derived from these. Since this is not yet done, repositories publishing data and tracking sample material record the literature based on these data and samples in their databases. In the case of the STD-DOI project, its metadata profile includes identifiers of related material, e.g. literature interpreting the data, related datasets, or samples from which the data were derived. These metadata can then be used to create ontologies interlinking literature

    A well-designed and comprehensive citation index for the social sciences and humanities has many potential uses, but has yet to be realised. Significant parts of the scholarly production in these areas are not published in international journals, but in national scholarly journals, in book chapters...... or in monographs. The potential for covering these literatures more comprehensively can now be investigated empirically using a complete publication output data set from the higher education sector of an entire country (Norway). We find that while the international journals in the social sciences and humanities...... are promising for a more comprehensive coverage of the social sciences and humanities....

    As end-user demand for easy access to electronic full text continues to climb, an increasing number of information providers are combining that access with their other products and services, making navigating their Web sites by librarians seeking information on a given product or service more daunting than ever. One such provider of a complex array of products and services is Thomson Scientific. This paper looks at some of the many products and tools available from two of Thomson Scientific's businesses, Thomson ISI and Thomson ResearchSoft. Among the items of most interest to health sciences and veterinary librarians and their users are the variety of databases available via the ISI Web of Knowledge platform and the information management products available from ResearchSoft.

    Despite of its small size, the Central American country of Costa Rica is internationally recognized as one of the world leaders in conservation and as the Central American leader in science. There have been no recent studies on the country's scientific production. The objective of this study was to analyze the Costa Rican scientific output as represented in the Science Citation Index Expanded. All documents with "Costa Rica" in the address field from 1981 to 2010 were included (total 6 801 publications). Articles (79%) were more frequent than other types of publication and were mostly in English (83%). Revista de Biología Tropical published the most articles (17%), followed by Toxicon and Turrialba (2.5%). The New England Journal of Medicine had the highest impact factor (53.484) with nine articles. Of 5 343 articles with known institutional address, 63%were internationally collaborative articles (most with the USA) with h index 91 and citation per publication 18. A total of 81% of all articles were inter-institutionally collaborative articles, led by the Universidad de Costa Rica. This reflects research and education agreements among these countries. Universidad de Costa Rica ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. Studied subjects and journals in our sample are in agreement with dominant science fields and journals in Costa Rica. Articles with the highest citation were published in New England Journal of Medicine. The largest citation of medical articles reflects the general interest and wider readership of this subject. All corresponding and first authors of the high impact articles were not from Costa Rica. In conclusion, the scientific output of Costa Rican authors is strong in the areas related to conservation but the impact is higher for biomedical articles, and Costa Rican authors need to

    Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

  6. On the evolution and utility of annual citation indices

    2014-01-01

    We study the statistics of citations made to the top ranked indexed journals for Science and Social Science databases in the Journal Citation Reports using different measures. Total annual citation and impact factor, as well as a third measure called the annual citation rate are used to make the detailed analysis. We observe that the distribution of the annual citation rate has an universal feature - it shows a maximum at the rate scaled by half the average, irrespective of how the journals are ranked, and even across Science and Social Science journals, and fits well to log-Gumbel distribution. Correlations between different quantities are studied and a comparative analysis of the three measures is presented. The newly introduced annual citation rate factor helps in understanding the effect of scaling the number of citation by the total number of publications. The effect of the impact factor on authors contributing to the journals as well as on editorial policies is also discussed.

    To determine the optimal databases to search for studies of faith-sensitive interventions for treating depression. We examined 23 health, social science, religious, and grey literature databases searched for an evidence synthesis. Databases were prioritized by yield of (1) search results, (2) potentially relevant references identified during screening, (3) included references contained in the synthesis, and (4) included references that were available in the database. We assessed the impact of databases beyond MEDLINE, EMBASE, and PsycINFO by their ability to supply studies identifying new themes and issues. We identified pragmatic workload factors that influence database selection. PsycINFO was the best performing database within all priority lists. ArabPsyNet, CINAHL, Dissertations and Theses, EMBASE, Global Health, Health Management Information Consortium, MEDLINE, PsycINFO, and Sociological Abstracts were essential for our searches to retrieve the included references. Citation tracking activities and the personal library of one of the research teams made significant contributions of unique, relevant references. Religion studies databases (Am Theo Lib Assoc, FRANCIS) did not provide unique, relevant references. Literature searches for reviews and evidence syntheses of religion and health studies should include social science, grey literature, non-Western databases, personal libraries, and citation tracking activities.

    Modern information and communication technologies, especially the Internet, have diminished the role of spatial distances and territorial boundaries on the access and transmissibility of information. This has enabled scientists for closer collaboration and internationalization. Nevertheless, geography remains an important factor affecting the dynamics of science. Here we present a systematic analysis of citation and collaboration networks between cities and countries, by assigning papers to the geographic locations of their authors' affiliations. The citation flows as well as the collaboration strengths between cities decrease with the distance between them and follow gravity laws. In addition, the total research impact of a country grows linearly with the amount of national funding for research & development. However, the average impact reveals a peculiar threshold effect: the scientific output of a country may reach an impact larger than the world average only if the country invests more than about 100,000 USD per researcher annually.

  11. Aberration of the Citation.

    Science.gov (United States)

    Moustafa, Khaled

    2016-01-01

    Multiple inherent biases related to different citation practices (for e.g., self-citations, negative citations, wrong citations, multi-authorship-biased citations, honorary citations, circumstantial citations, discriminatory citations, selective and arbitrary citations, etc.) make citation-based bibliometrics strongly flawed and defective measures. A paper can be highly cited for a while (for e.g., under circumstantial or transitional knowledge), but years later it may appear that its findings, paradigms, or theories were untrue or invalid anymore. By contrast, a paper may remain shelved or overlooked for years or decades, but new studies or discoveries may actualize its subject at any moment. As citation-based metrics are transformed into "commercial activities," the "citation credit" should be considered on a commercial basis too, in the sense that "citation credit" should be shared out as a "citation dividend" by shareholders (coauthors) averagely or proportionally to their contributions but not fully appropriated by each of them. At equal numbers of citations, the greater number of authors, the lower "citation credit" should be and vice versa. Overlooking the presence of distorted and subjective citation practices makes many people and administrators "obsessed" with the number of citations to such an extent to run after "highly cited" authors and to create specialized citation databases for commercial purposes. Citation-based bibliometrics, however, are unreliable and unscientific measures; citation counts do not mean that a more cited work is of a higher quality or accuracy than a less cited work because citations do not measure the quality or accuracy. Citations do not mean that a highly cited author or journal is more commendable than a less cited author or journal. Citations are not more than countable numbers: no more, no less.

    BACKGROUND Disseminating information derived from systematic reviews is a fundamental step for translating evidence into practice. OBJECTIVE To determine which features of dermatological SR are associated with systematic review dissemination, using citation rates as an indicator. METHODS Dermatological systematic reviews published between 2008 and 2012 were obtained from Scopus, the ISI Web of Sciences and the Cochrane Skin Group. Bibliometric data of every systematic review were collected and analyzed. RESULTS A total of 320 systematic reviews were analyzed. Univariable analysis showed that the journal impact factor, number of authors, and total references cited were positively associated with the number of citations. There was a significant difference in the median number of citations with regard to the corresponding author's country, type of skin disease, type of funding, and presence of international collaboration. Cochrane reviews were significantly associated with a lower number of citations. Multivariable analysis found that the number of authors, number of references cited and the corresponding author from United Kingdom were independently correlated with many citations. Cochrane systematic reviews tended to be independently associated with a lower number of citations. CONCLUSIONS Citation number to systematic reviews may be improving by increasing the number of authors, especially collaborative authors, and the number of cited references. The reasons for the association of Cochrane SRs with fewer citations should be addressed in future studies. PMID:26560209

    The meta-analysis is regarded as an important evidence for making scientific decision. The database of ISI Web of Science collected a great number of high quality literatures including meta-analysis literatures. However, it is significant to understand the general characteristics of meta-analysis literatures to outline the perspective of meta-analysis. In this present study, we summarized and clarified some features on these literatures in the database of ISI Web of Science. We retrieved the meta-analysis literatures in the database of ISI Web of Science including SCI-E, SSCI, A&HCI, CPCI-S, CPCI-SSH, CCR-E, and IC. The annual growth rate, literature category, language, funding, index citation, agencies and countries/territories of the meta-analysis literatures were analyzed, respectively. A total of 95,719 records, which account for 0.38% (99% CI: 0.38%-0.39%) of all literatures, were found in the database. From 1997 to 2012, the annual growth rate of meta-analysis literatures was 18.18%. The literatures involved in many categories, languages, fundings, citations, publication agencies, and countries/territories. Interestingly, the index citation frequencies of the meta-analysis were significantly higher than that of other type literatures such as multi-centre study, randomize controlled trial, cohort study, case control study, and cases report (P<0.0001). The increasing numbers, intensively global influence and high citations revealed that the meta-analysis has been becoming more and more prominent in recent years. In future, in order to promote the validity of meta-analysis, the CONSORT and PRISMA standard should be continuously popularized in the field of evidence-based medicine.

  18. Using incomplete citation data for MEDLINE results ranking.

    2005-01-01

    Information overload is a significant problem for modern medicine. Searching MEDLINE for common topics often retrieves more relevant documents than users can review. Therefore, we must identify documents that are not only relevant, but also important. Our system ranks articles using citation counts and the PageRank algorithm, incorporating data from the Science Citation Index. However, citation data is usually incomplete. Therefore, we explore the relationship between the quantity of citation information available to the system and the quality of the result ranking. Specifically, we test the ability of citation count and PageRank to identify "important articles" as defined by experts from large result sets with decreasing citation information. We found that PageRank performs better than simple citation counts, but both algorithms are surprisingly robust to information loss. We conclude that even an incomplete citation database is likely to be effective for importance ranking.

    Full Text Available Databases catalogue the corpus of research literature into scientific categories and report classes of bibliometric data such as the number of citations to articles, the number of authors, journals, funding agencies, institutes, references, etc. The number of articles and citations in a category are gauges of productivity and scientific impact but a quantitative basis to compare researchers between categories is limited. Here, we compile a list of bibliometric indicators for 236 science categories and citation rates of the 500 most cited articles of each category. The number of citations per paper vary by several orders of magnitude and are highest in multidisciplinary sciences, general internal medicine, and biochemistry and lowest in literature, poetry, and dance. A regression model demonstrates that citation rates to the top articles in each category increase with the square root of the number of articles in a category and decrease proportionately with the age of the references: articles in categories that cite recent research are also cited more frequently. The citation rate correlates positively with the number of funding agencies that finance the research. The category h-index correlates with the average number of cites to the top 500 ranked articles of each category (R2=0.997. Furthermore, only a few journals publish the top 500 cited articles in each category: four journals publish 60% (σ=±20% of these and ten publish 81% (σ=±15%.

    The analysis of cancer scientific production in Puerto Rico is largely unexplored. The objective of this study was to characterize trends in cancer-related research publications by authors affiliated to Puerto Rican institutions in recent decades. Manuscripts were retrieved from the Science Citation Index (SCI) database from 1982 to 2009. Search criterions were that the author's affiliation field contained some institution located in Puerto Rico and that the manuscripts were related to cancer research (according to keywords from the National Cancer Institute' cancer definition). Indexes measured in our analysis included number and type of manuscript, scientific collaboration, author's affiliation, and journal visibility. All the analyses were conducted using ProCite for bibliographic information management and STATA and SEER Joinpoint for the statistical inquiry. From 1982-2009, cancer-related papers authored by scientists located in Puerto Rico came to 451. Over the last three decades the scientific production underwent significant growth (APC = 6.4%, p scientific production in Puerto Rico underwent constant growth during the last three decades. A complete understanding of citing, publishing, and collaboration patterns in Puerto Rico is critical to researchers, policy makers, and health-care professionals in order to make informed decisions about cancer research priorities.

    Full Text Available Despite of its small size, the Central American country of Costa Rica is internationally recognized as one of the world leaders in conservation and as the Central American leader in science. There have been no recent studies on the country’s scientific production. The objective of this study was to analyze the Costa Rican scientific output as represented in the Science Citation Index Expanded. All documents with “Costa Rica” in the address field from 1981 to 2010 were included (total 6 801 publications. Articles (79% were more frequent than other types of publication and were mostly in English (83%. Revista de Biología Tropical published the most articles (17%, followed by Toxicon and Turrialba (2.5%. The New England Journal of Medicine had the highest impact factor (53.484 with nine articles. Of 5 343 articles with known institutional address, 63%were internationally collaborative articles (most with the USA with h index 91 and citation per publication 18. A total of 81% of all articles were inter-institutionally collaborative articles, led by the Universidad de Costa Rica. This reflects research and education agreements among these countries. Universidad de Costa Rica ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. Studied subjects and journals in our sample are in agreement with dominant science fields and journals in Costa Rica. Articles with the highest citation were published in New England Journal of Medicine. The largest citation of medical articles reflects the general interest and wider readership of this subject. All corresponding and first authors of the high impact articles were not from Costa Rica. In conclusion, the scientific output of Costa Rican authors is strong in the areas related to conservation but the impact is higher for biomedical articles, and Costa Rican

    To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

    To describe the impact factor of Archivos de Bronconeumología from 1997 until 2000 and to identify the patterns of citation of the journal and topics having the greatest impact. SCISEARCH was used to locate citations of articles published by Archivos de Bronconeumología between 1995 and 1999. The following data were collected for each article: year of publication, authors, journal, country of publication, language, specialty or specialties, institution(s), residence of the first author and topic. The impact factor was calculated as the ratio of citations received in one year by articles published in Archivos de Bronconeumología during the two previous years and the total number of articles published by Archivos de Bronconeumología over the two years under study. The impact factor of Archivos de Bronconeumología was 0.107 in 1997, 0.089 in 1998, 0.105 in 1999 and 0.119 in 2000. Citations were found in a wide range of source journals, with respiratory system publications having little weight. Citations were made mainly by Spanish authors (75%) and self-citation was restrained (21.1%). Topics related to tuberculosis and respiratory infections (23.6% of the citations received) and chronic obstructive pulmonary disease (12.5%) made the greatest impact. The impact factor of Archivos de Bronconeumología is modest, although higher than those of some other publications included in Journal Citation Reports.

    Science.gov (United States)

    Lomonte, Bruno; Ainsworth, Shirley

    2002-01-01

    This study analyzed the publications of authors from Costa Rican institutions that were included in the Science Citation Index (SCI) during 1999-2001. Out of the 722 references detected, distributed in 328 journals, 90.7% corresponded to original research articles. The total productivity figures showed a moderately increasing trend, both in absolute and population-adjusted terms, in concordance with previous data recorded for the period 1980-1998. The contribution of Revista de Biología Tropical to these figures corresponded to 10.0%, 8.9%, and 19.1%, for the years 1999, 2000, and 2001, respectively. The subject distribution of articles followed a similar pattern to that described for 1980-1998, with a predominance of biomedical (33.3%) and biological (27.5%) sciences, followed by agronomical (15.5%) sciences, chemistry (13.6%), physics (5.0%), geological sciences (3.6%), and mathematics (1.5%). Citation analyses for individual publications (up to July 15, 2002) revealed that only 45.2% of the articles had been cited at least once. The ten most cited references were analyzed, varying from 26 to 114 citations. The average citation per article was 2.60, and the average number of authors per article was 2.92. In agreement with data from 1980-1998, the University of Costa Rica appeared as the institution with highest productivity of SCI publications during 1999-2001, with a contribution of 50.0%. The percentage of publications performed without the participation of foreign co-authors showed a change in its decreasing trend of 1980-1998, stabilizing near the range of 25-30% during the period 1999-2001.

    Full Text Available In Serbia, the influence of the society on humanistic sciences is mainly perpetrated through state funding of scientific projects. Such funding currently involves valuation of the results of a scientific work by applying citation metrics methods, which are not acknowledged in Europe. Citation metrics in the USA, where it was created, lead to caricature forms of scientific products, composed of several pages of text and a great number of cited (quoted titles. Citation metrical-citation manic procedure can lead to the elimination of the domestic humanistic sciences and the implementation of third rate quoteres, who, along with hollow articles filled with mutually intertwined citations, fulfill requirements, unconsciously(? set by the authorized Ministry and University.

    Full Text Available The purpose of the present study was to analyze the interdisciplinary relations of “Library Science and Information Science”. For this purpose the subject categories of citing and cited journals of these fields were investigated in JCR database during the period of 1987-1997 and 2003-2013, and through the comparsion of obtained results the impact of information technology on the development of “LIS” interdisciplinarity was investigated. Methedology of the research was co-citation analysis of journals in scientometrics studies. Also the research was performed using the conventional techniques of scientometrics including Bradford law, Ward hierarchical clustering approach in statistical software SPSS, and the new measure including Proximity index. Research community includes citing and cited journals of 56 “LIS” journals during 1987-1997 and 83 journals during 2003-2013 in Journals Ctiation Report (JCR database. The results showed that “LIS” has been influenced by other subject categories more than affecting them. For example, the number of journals which “LIS” cited from 1758 (in the first period has increased to 5303 (in the second period. Co-occurrence matrix of core citing and cited subject categories was analyzed, and three main clusters in the first period and seven clusters in the second period were drawn. In general, the amount and quality of co-occurrence of subject categories in clusters showed that the domain and variety of affecting and affected subject categories were expanded in the second period. Structural similarity of clusters for affecting and affected subject categories calculated. Results showed that structural similarity of clusters in the second period was %10 higher than in the first period. Also, the Structural similarity of affecting clusters of “LIS” was more than affected clusters. Assessment of difference between subject categories groups by ANOVA and Tukey Post hoc tests showed that there were

    This study aimed to identify and analyze characteristics of highly cited articles published in the Web of Science category of health care sciences and services from 1958 to 2012. Articles that have been cited at least 100 times were assessed regarding publication outputs, distribution of outputs in journals, publications of authors, institutions, countries as well as citation life cycles of the articles with the highest total citations since its publication up to 2012 and the highest citations in 2012. Six bibliometric indicators were used to evaluate source countries, institutions, and authors. Total citations from the time the articles were first published to the end of 2012 and citations in 2012 only were applied. Additionally, Y-index was applied to evaluate publication characteristics of authors. A high percentage of authors had the same numbers of first author and corresponding author status of highly cited articles in health care sciences and services field. RESULTS showed that 890 of the most highly referenced articles, published between 1977 and 2009, had been cited at least 100 times. Medical Care and Journal of General Internal Medicine published the most highly cited articles. The United States produced 76% of highly cited articles and also published the most number of independent, internationally collaborative, first authored, corresponding authored, and single author highly cited articles. The Harvard University was the most productive institute and was number one for the total highly cited articles, inter-institutionally collaborative articles, single institution articles, first author articles, and corresponding author articles. The application of quantitative techniques in the analysis of highly cited articles can improve the researchers' understanding of the directions in health care sciences and services field. Y-index is useful for the evaluation of contributing authors.

    Directory of Open Access Journals (Sweden)

    Sanjica Faletar Tanacković

    2013-02-01

    Full Text Available The aim of this paper is to describe and critically analyse the application of citation analysis in the collection evaluation in academic libraries, and to present the results of the study. The study, first of its kind in Croatia, was carried out in the information sciences collection at the Faculty of Humanities and Social Sciences in Osijek. Based on many studies from abroad done in the academic environment, the citation analysis, despite its disadvantages, proved to be a valid method for the collection of indicators of real use of (library information sources. The study analysed citation patterns, characteristics of information sources used by respondents and the accessibility of these sources in the academic library. Its aim was also to test the method of citation analysis in the context of library collection evaluation. The samples used in this study were papers published in 2010 by the students and teachers of the Department of Information Sciences in Osijek. The data analysis showed that while students preferred electronic information sources, teachers preferred print sources. Also, periodicals and monographs were top two information types used in the compilation of studied publications. However, students used undefined type of web resources such as presentations and commercial and educational websites to a great extent. As far as accessibility of sources used is concerned, the results show that library offers access to 60% of periodicals used and approximately 25% of monographs. In order to minimize the limitations of this quantitative method and to obtain valid and reliable indicators of citation patterns and use of (library information sources by students and teachers at the given Department, this study should be carried out longitudinally. It should also be complemented with a qualitative study (e.g. interview with teachers and students.

  20. Citations in Life Science Patents to Publicly Funded Research at Academic Medical Centers.

    Sampat, Bhaven N; Pincus, Harold Alan

    2015-12-01

    The contributions of Academic Medical Centers (AMCs) to biomedical innovation have been difficult to measure because of the challenges involved in tracing knowledge flows from their origin to their uses. The authors examined patent citation linkages between AMC research funded by the National Institutes of Health (NIH) and patents. In prospective analyses, they examine the extent to which articles resulting from NIH grants to AMCs awarded between 1990 and 1995 were cited in drug and medical patents. The authors then examine the extent to which these patents are associated with marketed drugs. In retrospective analyses, they examine the share of drugs approved between 2000 and 2009 that have citation links to NIH-funded AMC research. The prospective analyses show over a third of AMC grants resulted in publications that were cited in patents. Most the patents are drug and biotechnology patents, and are assigned to private firms. Patents citing NIH-funded AMC publications were associated with 106 new FDA approved drugs, half of which are new molecular entities and a quarter of which are priority NMEs. The retrospective analyses showed that about half of the new molecular entities approved over the 2000-2009 period had citations links to NIH-funded AMC research. There are strong links between articles from NIH-funded AMC research and private sector medical patenting, including drugs. More research is needed to better understand the types of links the citations represent and their implications for public policy. © 2015 Wiley Periodicals, Inc.

  1. "Smart Girls" versus "Sleeping Beauties" in the Sciences: The Identification of Instant and Delayed Recognition by Using the Citation Angle

    CERN Document Server

    Ye, Fred Y

    2016-01-01

    In recent years, a number of studies have introduced methods for identifying papers with delayed recognition (so called "sleeping beauties", SBs) or have presented single publications as cases of SBs. Most recently, Ke et al. (2015) proposed the so called "beauty coefficient" (denoted as B) to quantify how much a given paper can be considered as a paper with delayed recognition. In this study, the new term "smart girl" (SG) is suggested to differentiate instant credit or "flashes in the pan" from SBs. While SG and SB are qualitatively defined, the dynamic citation angle \\b{eta} is introduced in this study as a simple way for identifying SGs and SBs quantitatively - complementing the beauty coefficient B. The citation angles for all articles from 1980 (n=166870) in natural sciences are calculated for identifying SGs and SBs and their extent. We reveal that about 3% of the articles are typical SGs and about 0.1% typical SBs. The potential advantages of the citation angle approach are explained.

    The main purpose of this paper is to investigate the intellectual structure of the research on educational technology in science education (ETiSE) within the most recent years (2008-2013). Based on the criteria for educational technology research and the citation threshold for educational co-citation analysis, a total of 137 relevant ETiSE papers were identified from the International Journal of Science Education, the Journal of Research in Science Teaching, Science Education, and the Journal of Science Education and Technology. Then, a series of methodologies were performed to analyze all 137 source documents, including document co-citation analysis, social network analysis, and exploratory factor analysis. As a result, 454 co-citation ties were obtained and then graphically visualized with an undirected network, presenting a global structure of the current ETiSE research network. In addition, four major underlying intellectual subfields within the main component of the ETiSE network were extracted and named as: (1) technology-enhanced science inquiry, (2) simulation and visualization for understanding, (3) technology-enhanced chemistry learning, and (4) game-based science learning. The most influential co-citation pairs and cross-boundary phenomena were then analyzed and visualized in a co-citation network. This is the very first attempt to illuminate the core ideas underlying ETiSE research by integrating the co-citation method, factor analysis, and the networking visualization technique. The findings of this study provide a platform for scholarly discussion of the dissemination and research trends within the current ETiSE literature.

    Full Text Available It is important for scientists to share the studies they conduct with other researchers as well as following developments in their area. The best way to share the results of scientific studies which require a long time and a lot of effort with other scientists is to publish them in internationally accepted and distinguished journals. In this study, we aim at assessing international publications compiled through contributions of forensic medicine expert and their assistants in Turkey between 2000 and 2004. This has been carried out according to the criteria of the encouragement program of TUBITAK-International Scientific Publications and by analyzing the contribution of these publications to those in the scope of the Science Citation Index-Journal Citation reports in Turkey. Thus, we used the “Pub Med and Web of Science” data base. Between 01.01.2000 and 31.12.2004, in the journals in the scope of Web of Science data base, a total of 86 publications were produced by forensic medicine experts and their assistants. The ratio of contributions to the Turkey originated publications rose to 0.23% from 0.11% in the last two years. It determinated that 70 of the publications (81.4% were full articles and 15 of them (17.4% were partial articles. According to the criteria of the TUBITAK International Scientific Publications Encouragement Program, 3 of the publications (3.5% took place A Group, 54 of them (62.8% in the B Group and 23 of them (26.7% in the C Group journal lists.

    2015-10-15

    The data on the top 20 journals in the Science Citation Index(Expanded) for 10 years from 2005 to 2014 indicated the first and second positions for Korean papers were occupied by the Korean journals, which implied the need for globalization of target journals to publish Korean papers. Further study is required for comparative analysis of the factors impacting on the number of papers and citations, which is the criteria for quality evaluation of papers, in other area than the Nuclear Energy and Engineering to which this study was limited. As the media for research process and results, papers play an important role in the evaluation of research projects. While the traditional methods for evaluation of research results have been focused on quantity aspects, the implication of quality aspect is increasingly recognized. Most national labs have begun to shift from quantity to quality in their criteria for overall evaluation of research results. It is therefore desired to maximize the quality level of the research papers for which the trends in citation as quality indicator could be analyzed as well as the quantity aspect. This paper looks at the trends in the number of citation and papers as the indicators of quality and quantify, as drawn from Scopus Data Base. It also suggest top 5 Science Citation Index(Expanded) journals in terms of increase rate in both number of papers and citations. The purpose is to compare them with top 20 Science Citation Index(Expanded) journals in which Korea Atomic Energy Research researchers have published their papers in the past 10 years from 2005 to 2014 were submitted. This paper looked at the trends in the number of papers and citations as an indicator of quality of the research papers in the area of Nuclear Energy and Engineering which is in fact a limitation to the key subject area, not covering the whole nuclear science and technology.

    Full Text Available Aim: Informal citations is bibliographic information (title or Internet address, citing sources of information resources for informal scholarly communication and always neglected in traditional citation databases. This study is done, in order to answer the question of whether informal citations in the web environment are traceable. The present research aims to determine what proportion of web citations of Google search engine is related to formal and informal citation. Research method: Webometrics is the method used. The study is done on 1344 research articles of 98 open access journal, and the method that is used to extract the web citation from Google search engine is “Web / URL citation extraction". Findings: The findings showed that ten percent of the web citations of Google search engine are formal and informal citations. The highest formal citation in the Google search engine with 19/27% is in the field of library and information science and the lowest official citation by 1/54% is devoted to the field of civil engineering. The highest percentage of informal citations with 3/57% is devoted to sociology and the lowest percentage of informal citations by 0/39% is devoted to the field of civil engineering. Journal Citation is highest with 94/12% in the surgical field and lowest with 5/26 percent in the philosophy filed. Result: Due to formal and informal citations in the Google search engine which is about 10 percent and the reduction of this amount compared to previous research, it seems that track citations by this engine should be treated with more caution. We see that the amount of formal citation is variable in different disciplines. Cited journals in the field of surgery, is highest and in the filed of philosophy is lowest, this indicates that in the filed of philosophy, that is a subset of the social sciences, journals in scientific communication do not play a significant role. On the other hand, book has a key role in this filed

    2011-04-01

    This study was designed to investigate the influence of journals indexed by Science Citation Index (SCI) on Chinese medical journals. Articles on medicine written by Chinese and the journals that published these articles from 2000 to 2009 were searched using Science Citation Index Expanded (SCI-E) database, and the status and variation tendency of the impact factors (IF) of these journals were analyzed. Data of articles on medicine included Chinese Scientific and Technical Paper and Citations Data (CSTPCD) from 2000 to 2008 were searched (the data of 2009 have not been released). The included articles and the time-dependent changing profile were studied. These outcomes were evaluated as the fixed base relative or link relative when compared with the data of 2000 or those of last year, respectively. Geometric mean was used when mean increase was calculated and IF distribution was described with median. Totally 3774 articles from China were published by journals indexed by SCI-E in 2000, and the number of articles published by Chinese authors increased every year. In 2008, 16 714 articles were indexed by SCI-E, 442.87% higher than those of 2000. The increment was 161.54% higher than that of articles published in the journals indexed by CSTPCD (281.33%) during the same period. From 2000 to 2009, the geometric mean of increase in the number of published articles from China in journals indexed by SCI-E was 20.87% but it was 18.21% in CSTPCD. From 2000 to 2009, the median of IF of SCI-E indexed journals that published Chinese medical articles was 1.866, 2.073, 2.390, 2.702, 2.409, 2.496, 2.380, 2.218, 2.280 and 2.331, respectively, and they did not increase or even decreased. The number of the articles indexed by SCI-E increased year by year, much faster than that of CSTPCD. However, it does not necessarily mean the increase in impact.

    Search engines and retrieval systems are popular tools at a life science desktop. The manual inspection of hundreds of database entries, that reflect a life science concept or fact, is a time intensive daily work. Hereby, not the number of query results matters, but the relevance does. In this paper, we present the LAILAPS search engine for life science databases. The concept is to combine a novel feature model for relevance ranking, a machine learning approach to model user relevance profiles, ranking improvement by user feedback tracking and an intuitive and slim web user interface, that estimates relevance rank by tracking user interactions. Queries are formulated as simple keyword lists and will be expanded by synonyms. Supporting a flexible text index and a simple data import format, LAILAPS can easily be used both as search engine for comprehensive integrated life science databases and for small in-house project databases. With a set of features, extracted from each database hit in combination with user relevance preferences, a neural network predicts user specific relevance scores. Using expert knowledge as training data for a predefined neural network or using users own relevance training sets, a reliable relevance ranking of database hits has been implemented. In this paper, we present the LAILAPS system, the concepts, benchmarks and use cases. LAILAPS is public available for SWISSPROT data at http://lailaps.ipk-gatersleben.de.

    This study examines the determinants of citation success among authors who have recently published their work in economic history journals. Besides offering clues about how to improve one's scientific impact, our citation analysis also sheds light on the state of the field of economic history....... Consistent with our expectations, we find that full professors, authors appointed at economics and history departments, and authors working in Anglo-Saxon and German countries are more likely to receive citations than other scholars. Long and co-authored articles are also a factor for citation success. We...... find similar patterns when assessing the same authors' citation success in economics journals. As a novel feature, we demonstrate that the diffusion of research — publication of working papers, as well as conference and workshop presentations — has a first-order positive impact on the citation rate....

    Full Text Available We report on attempts to put an astronomical database – the Sloan Digital Sky Survey science archive – in the cloud. We find that it is very frustrating to impossible at this time to migrate a complex SQL Server database into current cloud service offerings such as Amazon (EC2 and Microsoft (SQL Azure. Certainly it is impossible to migrate a large database in excess of a TB, but even with (much smaller databases, the limitations of cloud services make it very difficult to migrate the data to the cloud without making changes to the schema and settings that would degrade performance and/or make the data unusable. Preliminary performance comparisons show a large performance discrepancy with the Amazon cloud version of the SDSS database. These difficulties suggest that much work and coordination needs to occur between cloud service providers and their potential clients before science databases – not just large ones but even smaller databases that make extensive use of advanced database features for performance and usability – can successfully and effectively be deployed in the cloud. We describe a powerful new computational instrument that we are developing in the interim – the Data-Scope – that will enable fast and efficient analysis of the largest (petabyte scale scientific datasets.

    Bibliometric analysis is increasingly being used for research assessment. The main objective of this study was to assess research output in Urology and Nephrology subject from the Arab countries. Original scientific articles or reviews published from the 21 Arab countries in "Urology and Nephrology" subject were screened using the ISI Web of Science database. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies by analyzing the annual productivity, names of journals, citations; top 10 active institution and authors as well as country contribution to Urology and Nephrology research. Three thousand and seventy six documents in "urology and nephrology" subject category were retrieved from 104 journals. This represents 1.4% of the global research output in "urology and nephrology". Four hundred and two documents (12.66%) were published in Annales D Urologie Journal. The h-index of the retrieved documents was 57. The total number of citations, at the time of data analysis, was 30401 with an average citation of 9.57 per document. Egypt, with a total publication of 1284 (40.43%) ranked first among the Arab countries in "urology and nephrology" subject category. Mansoura University in Egypt was the most productive institution with a total of 561 (15.33%) documents. Arab researchers collaborated most with researchers from the United States of America (226; 7.12%) in urology and nephrology research. The present data reveals a good contribution of some Arab countries to the field of "urology and nephrology". More efforts are needed by some other Arab countries to bridge the gap in urology and nephrology research. Overall, the quality of urology/nephrology research is considered relatively high as measured by h-index. Cooperation in urology/nephrology research should be encouraged in the Arab world to bridge the gap with that from developed countries.

    In this study, the impact of self-citation (Journal and Author) on impact factor of Iranian English Medical journals in two international citation databases, Web of Science (WoS) and Islamic world science citation center (ISC), were compared by citation analysis. Twelve journals in WoS and 26 journals in ISC databases indexed between the years (2006-2009) were selected and compared. For comparison of self-citation rate in two databases, we used Wilcoxon and Mann-whitney tests. We used Pearson test for correlation of self-citation and IF in WoS, and the Spearman's correlation coefficient for the ISC database. Covariance analysis was used for comparison of two correlation tests. P. value was 0.05 in all of tests. There was no significant difference between self-citation rates in two databases (P>0.05). Findings also showed no significant difference between the correlation of Journal self-citation and impact factor in two databases (P=0.526) however, there was significant difference between the author's self-citation and impact factor in these databases (PImpact Factor of WoS was higher than the ISC.

    Full Text Available An unprecedented outbreak of the Ebola virus in 2014 claimed more than 1000 lives in West Africa and the World Health Organization declared a global public health emergency. This outbreak will undoubtedly promote additional research related to the Ebola virus and will create debate related to experimental drugs. This article identified the quantum of research in the field since 1991; the scientific disciplines that contributed to the field; the countries, organisations and authors that supported such research and the most cited articles. An increasing trend in annual production during 1991–2013 was observed. Journal of Virology, Journal of Infectious Diseases, and Virology were the three most productive journals in the field. Similarly, the field of virology dominated the 73 categories in which the Ebola research was classified. A total of 63 countries contributed to Ebola-related research, led by the USA. The most productive institutions were the United States Army Medical Research Institute of Infectious Diseases, the Centers for Disease Control and Prevention, and the National Institute of Allergy and Infectious Diseases. African countries were more likely to be involved in international collaboration than independent research. The most influential article exhibited a notable citation pattern and presented global trends in emerging infectious diseases.

    2017-11-01

    A bibliometric analysis based on the Science Citation Index Expanded from Web of Science was carried out to provide insights into research activities and trends of the environmental monitoring from 1993 to 2012. Study emphases covered publication outputs, language, categories, journals, countries/territories, institutions, words, and hot issues. The results indicated that the annual output of environmental monitoring publications increased steadily. The environmental sciences and analytical chemistry were the two most common categories. Environmental Monitoring and Assessment published the most articles. The USA and the UK ranked in the top two in terms of all five indicators. The U.S. Environmental Protection Agency took the leading position of the institutions in terms of publication output. The synthesized analysis by words in title, author keywords, and KeyWords Plus provided important clues for hot issues. Researchers paid more attention on water environment monitoring than other environmental factors. The contaminants including organic contaminants, heavy metal, and radiation were most common research focuses, and the organic contaminants and heavy metal of the degree of concern were gradually rising. Sensor and biosensor played an important role in the field of environmental monitoring devices. In addition to conventional device detection method, the remote sensing, GIS, and wireless sensor networks were the mainstream environmental monitoring methods. The international organization, social awareness, and the countries' positive and effective political and policies promoted the published articles.

    Stephen Hall, a freelance science writer and science-communication teacher, received the Walter Sullivan Award for Excellence in Science Journalism-Features at the AGU Fall Meeting Honors Ceremony, held on 5 December 2012 in San Francisco, Calif. Hall was honored for the article "At Fault?" published 15 September 2011 in Nature. The article examines the legal, personal, and political repercussions from a 2009 earthquake in L'Aquila, Italy for seismologists who had attempted to convey seismic risk assessments to the public. The 6.3 magnitude quake devastated the medieval town and caused more than 300 deaths. Six scientists and one government official were subsequently convicted of manslaughter and sentenced to prison for inadequately assessing and mischaracterizing the risks to city residents, despite the inexact nature of seismic risk assessment. The Sullivan award is for work published with a deadline pressure of more than 1 week.

    Academic publications are important for developing a medical specialty or discipline. Since family medicine is a rapidly growing medical specialty in Taiwan, this study aimed to analyze family medicine publications from 1993 to 2012 in Taiwan using the Web of Science database. Published academic articles submitted from departments/institutes of family medicine were retrieved and analyzed from the Web of Science database, which includes articles published in the Science Citation Index-Expanded and Social Science Citation Indexed journals from 1993 to 2012. Among 33,073 published articles submitted from the departments/institutes of family medicine worldwide during the years 1993-2012, 1552 articles (4.69%) were submitted from Taiwan, ranking fourth in the world after the USA, Canada, and Sweden. In total, 1409 articles from Taiwan, excluding meeting abstracts and corrections, were selected for further analyses. During these two decades, family medicine publications increased rapidly. There were 60 articles published during 1993-1997, 180 articles during 1998-2002, 334 articles during 2003-2007, and up to 836 articles during 2008-2012. However, the mean citation number of articles decreased from 19.0 to 17.7, 15.1, and 3.8, and the mean impact factor of published journals decreased from 3.41 to 3.15, 2.78 and 2.82 during the periods 1993-1997, 1998-2002, 2003-2007, and 2008-2012, respectively. Most articles belonged to the subject category of the Medicine, General and Internal category (194 articles, 13.8%), followed by Public Environmental Occupational Health (144 articles, 10.2%), Oncology (126 articles, 9.2%), Endocrinology Metabolism (111 articles, 7.9%), Geriatrics Gerontology (99 articles, 7.0%), and the Gastroenterology Hepatology category (85 articles, 6.0%). However, only six articles (0.4%) were published in the Primary Health Care category. Publications from departments/institutes of family medicine in Taiwan increased rapidly from 1993 to 2012.

    To analyze Spanish scientific productivity from 1999 through 2003 in the area of smoking research, in comparison with world and European Union research, based on data in the Science Citation (SCI) Index. This bibliometric study was carried out by searching the title field of the Science Citation Index Expanded. Descriptive statistics with 95% confidence intervals (CI) were compiled. Two-hundred ninety-two documents on smoking by Spanish authors were located. The most productive subspecialties were the group comprised of public health, education and health economics with 57 articles, and areas of the respiratory system, experimental research, and internal medicine with 36 articles each. The journals that published the largest number of articles located were Medicina Clínica, with 35 articles (12%) and Archivos de Bronconeumología with 20 (6.8%). International collaboration was undertaken with institutions in the United States of America and other European Union countries. The mean (SD) number of citations received was 5.12 (8.6) (range 59-0). Spain contributed 8.34% of the SCI-indexed smoking research overall and 12.85% of SCI-indexed smoking research from the European Union. Smoking research is developing appropriately in Spain and has high impact, even though output is modest. Factors associated with increased citation are international collaboration, language (being written in English), and having a non-Spanish first author.

    Full Text Available Background: Academic collaboration is sharing the expertise, resources and abilities by researchers. This study examined academic collaboration among the authors of articles published in Iranian English language journals of ministry of health, indexed in the Web of Science and its correlation with article citations, 2005-2011. Methods: This study was a descriptive-analytical and cross-sectional study. The data were collected using a researcher-designed checklist. The study population was 6388 articles from 21 Iranian English language journals of ministry of health, indexed in the Web of Science. Data were collected by referring to each journal and counting the number of authors and citations allocated to any article. The obtained data were analyzed by SPSS and Excel software. Results: A total of 6388 articles published in 21 journals were analyzed according to the intended criteria. %17.8 of journals was monthly, %19.6 was tow-monthly and% 62.7 was quarterly. On average, 4.37 authors collaborated in writing each article. The mean of collaborative coefficient was 0.67. There was positively significant correlation between the number of authors and the number of citations to each article. Conclusion: The academic collaboration among the authors of examined articles enjoyed a favorable status, which is indicative of spirit of teamwork among the Iranian researchers. However, the rate of citations to articles in the examined journals was not in a good condition; hence, the factors affecting citation to articles, especially academic collaboration between researchers should be taken into consideration.

  1. Citation searching: a systematic review case study of multiple risk behaviour interventions.

    Wright, Kath; Golder, Su; Rodriguez-Lopez, Rocio

    2014-06-03

    The value of citation searches as part of the systematic review process is currently unknown. While the major guides to conducting systematic reviews state that citation searching should be carried out in addition to searching bibliographic databases there are still few studies in the literature that support this view. Rather than using a predefined search strategy to retrieve studies, citation searching uses known relevant papers to identify further papers. We describe a case study about the effectiveness of using the citation sources Google Scholar, Scopus, Web of Science and OVIDSP MEDLINE to identify records for inclusion in a systematic review.We used the 40 included studies identified by traditional database searches from one systematic review of interventions for multiple risk behaviours. We searched for each of the included studies in the four citation sources to retrieve the details of all papers that have cited these studies.We carried out two analyses; the first was to examine the overlap between the four citation sources to identify which citation tool was the most useful; the second was to investigate whether the citation searches identified any relevant records in addition to those retrieved by the original database searches. The highest number of citations was retrieved from Google Scholar (1680), followed by Scopus (1173), then Web of Science (1095) and lastly OVIDSP (213). To retrieve all the records identified by the citation tracking searching all four resources was required. Google Scholar identified the highest number of unique citations.The citation tracking identified 9 studies that met the review's inclusion criteria. Eight of these had already been identified by the traditional databases searches and identified in the screening process while the ninth was not available in any of the databases when the original searches were carried out. It would, however, have been identified by two of the database search strategies if searches had been

    As research in Earth Science becomes more data intensive, a critical requirement of data archives is that data needs to be easily discovered, accessed, and used. One approach to improving data discovery and access is through data citations coupled with Digital Object Identifiers (DOI). Beginning in 1998, the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has issued data product citations that have been accepted and used in AGU and other peer-reviewed journals. Citation elements established by the ORNL DAAC are similar to those used for journal articles (authors, titles, information to locate, and version), and beginning in 2007 included a DOI that is persistent, actionable, specific, and complete. The citation approach used at the DAAC also allows for referring to specific subsets of the data, by including within the citation the temporal and spatial portions of the data actually used. Citations allow others to find data and reproduce the results of the research article, and also use those data to test new hypotheses, design new sample collections, or construct or evaluate models. In addition to enhancing discovery and access of the data used in a research article, the citation gives credit to data generators, data centers and their funders, and, through citation indices, determine the scientific impact of a data set. The ORNL DAAC has developed a database that links research articles and their use of ORNL DAAC data products. The database allows determination of who, in which journal, and how the data have been used, in a manner analogous to author citation indices. The ORNL DAAC has been an initial contributor to the Thomson Reuters Data Citation Index. In addition, research data products deposited at the ORNL DAAC are linked using DOIs to relevant articles in Elsevier journals available on ScienceDirect. The ultimate goal of this implementation is that citations to data products become a routine part of the scientific process.

    The aims of this study were to identify the most cited articles in Periodontology published from January 1990 to March 2005; and to analyse the differences between citation Classics and less cited articles. The search was carried out in four international periodontal journals: Journal of Periodontology, Journal of Clinical Periodontology, International Journal of Periodontics and Restorative Dentistry and Journal of Periodontal Research. The Classics, that are articles cited at least 100 times, were identified using the Science Citation Index database. From every issue of the journals that contained a Classic, another article was randomly selected and used as a Control. Fifty-five Classics and 55 Controls were identified. Classic articles were longer, used more images, had more authors, and contained more self-references than Controls. Moreover Classics had on the average a bigger sample size, often dealt with etiopathogenesis and prognosis, but were rarely controlled or randomized studies. Classic articles play an instructive role, but are often non-Controlled studies.

    Acupuncture is a rapidly growing medical specialty worldwide. This study aimed to analyze the acupuncture publications from 1988 to 2015 by using the Web of Science (WoS) database. Familiarity with the trend of acupuncture publications will facilitate a better understanding of existing academic research in acupuncture and its applications. Academic articles published focusing on acupuncture were retrieved and analyzed from the WoS database which included articles published in Science Citation Index-Expanded and Social Science Citation Indexed journals from 1988 to 2015. A total of 7450 articles were published in the field of acupuncture during the period of 1988-2015. Annual article publications increased from 109 in 1988 to 670 in 2015. The People's Republic of China (published 2076 articles, 27.9%), USA (published 1638 articles, 22.0%) and South Korea (published 707 articles, 9.5%) were the most abundantly prolific countries. According to the WoS subject categories, 2591 articles (34.8%) were published in the category of Integrative and Complementary Medicine, followed by Neurosciences (1147 articles, 15.4%), and General Internal Medicine (918 articles, 12.3%). Kyung Hee University (South Korea) is the most prolific organization that is the source of acupuncture publications (365 articles, 4.9%). Fields within acupuncture with the most cited articles included mechanism, clinical trials, epidemiology, and a new research method of acupuncture. Publications associated with acupuncture increased rapidly from 1988 to 2015. The different applications of acupuncture were extensive in multiple fields of medicine. It is important to maintain and even nourish a certain quantity and quality of published acupuncture papers, which can play an important role in developing a medical discipline for acupuncture.

    2014-10-01

    An overview of the Data Citation Index is provided. Thomson Reuters developed this resource in response to a stated desire among members of the research community for increased attribution of non-traditional scholarly output. Launched in October of 2012 on the Web of science research platform, its aims include linking published research articles to their underlying data sets and tracking the citation of the data, as well as encouraging bibliographic citation of data. Cross-disciplinary search capabilities in the Index enable new possibilities for data discovery and synthesis. Data repositories are evaluated with respect to various selection criteria, with particular attention to their relevance to scientific and scholarly research. Index content reflects current data deposition practices. As data citation standards and practices continue to move toward widespread formalization and adoption, the initiative seeks to address issues of data citation, reuse, and author credit in a developing climate.

  11. Citation Analysis for the Modern Instructor: An Integrated Review of Emerging Research

    2013-07-01

    Full Text Available While online instructors may be versed in conducting e-Research (Hung, 2012; Thelwall, 2009, today’s faculty are probably less familiarized with the rapidly advancing fields of bibliometrics and informetrics. One key feature of research in these areas is Citation Analysis, a rather intricate operational feature available in modern indexes such as Web of Science, Scopus, Google Scholar, and PsycINFO. This paper reviews the recent extant research on bibliometrics within the context of citation analysis. Particular focus is on empirical studies, review essays, and critical commentaries on citation-based metrics across interdisciplinary academic areas. Research that relates to the interface between citation analysis and applications in higher education is discussed. Some of the attributes and limitations of citation operations of contemporary databases that offer citation searching or cited reference data are presented. This review concludes that: a citation-based results can vary largely and contingent on academic discipline or specialty area, b databases, that offer citation options, rely on idiosyncratic methods, coverage, and transparency of functions, c despite initial concerns, research from open access journals is being cited in traditional periodicals, and d the field of bibliometrics is rather perplex with regard to functionality and research is advancing at an exponential pace. Based on these findings, online instructors would be well served to stay abreast of developments in the field.

    Torres-Salinas, Daniel

    2012-12-01

    Full Text Available The absence of books and book chapters in the Web of Science Citation Indexes (SCI, SSCI and A&HCI has always been considered an important flaw but the Thomson Reuters ‘Book Citation Index’ database was finally available in October of 2010 indexing 29,618 books and 379,082 book chapters. The Book Citation Index opens a new window of opportunities for analyzing Humanities and Social Sciences from a bibliometric point of view. The main objective of this article is to analyze different impact indicators referred to the scientific publishers included in the Book Citation Index for the Social Sciences and Humanities fields during 2006-2011. This way we construct what we have called the ‘Book Publishers Citation Reports’. For this, we present a total of 19 rankings according to the different disciplines in Humanities & Arts and Social Sciences & Law with six indicators for scientific publishers.

    La ausencia de libros y capítulos de libros en los índices de citas presentes en las bases de datos de la Web of Science ha sido tradicionalmente una de sus más importantes debilidades. Sin embargo, Thomson Reuters en Octubre de 2010 lanzó el Book Citation Index, un nuevo índice de citas que contaba con 29.618 libros y 379.082 capítulos de libros. Este producto ha abierto nuevas posibilidades para el análisis bibliométrico de campos como las Humanidades y las Ciencias Sociales. Precisamente el objetivo principal de esta nota es analizar a través de diferentes indicadores las editoriales de los ámbitos de Humanidades y Ciencias Sociales indexadas en el Book Citation Index durante los años 2006-2011. Más concretamente se ha probado la posibilidad de desarrollar un ranking de editoriales de libros basado en la citación y la producción de las mismas. Para ello se presentan una colección de rankings con seis indicadores bibliométricos para un total de 19 disciplinas científicas.

    The bibliography contains citations concerning chlorofluorocarbons (CFC's), and efforts to find substitute materials in response to the need to lessen the environmental impact of CFC on the ozone layer, as agreed to in the international Montreal Protocol. CFC alternatives are expected to be used as aerosol propellants, blowing agents, refrigerants, fire extinguishants, and solvents. References to the effects of CFC on ozone are found in separate bibliographies. (Contains 250 citations and includes a subject term index and title list.)

  17. Inaccurate Citations in Biomedical Journalism: Effect on the Impact Factor of the American Journal of Roentgenology.

    Karabulut, Nevzat

    2017-03-01

    The aim of this study is to investigate the frequency of incorrect citations and its effects on the impact factor of a specific biomedical journal: the American Journal of Roentgenology. The Cited Reference Search function of Thomson Reuters' Web of Science database (formerly the Institute for Scientific Information's Web of Knowledge database) was used to identify erroneous citations. This was done by entering the journal name into the Cited Work field and entering "2011-2012" into the Cited Year(s) field. The errors in any part of the inaccurately cited references (e.g., author names, title, year, volume, issue, and page numbers) were recorded, and the types of errors (i.e., absent, deficient, or mistyped) were analyzed. Erroneous citations were corrected using the Suggest a Correction function of the Web of Science database. The effect of inaccurate citations on the impact factor of the AJR was calculated. Overall, 183 of 1055 citable articles published in 2011-2012 were inaccurately cited 423 times (mean [± SD], 2.31 ± 4.67 times; range, 1-44 times). Of these 183 articles, 110 (60.1%) were web-only articles and 44 (24.0%) were print articles. The most commonly identified errors were page number errors (44.8%) and misspelling of an author's name (20.2%). Incorrect citations adversely affected the impact factor of the AJR by 0.065 in 2012 and by 0.123 in 2013. Inaccurate citations are not infrequent in biomedical journals, yet they can be detected and corrected using the Web of Science database. Although the accuracy of references is primarily the responsibility of authors, the journal editorial office should also define a periodic inaccurate citation check task and correct erroneous citations to reclaim unnecessarily lost credit.

    2014-09-01

    This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

    The past year has seen movement on several fronts for improving software citation, including the Center for Open Science's Transparency and Openness Promotion (TOP) Guidelines, the Software Publishing Special Interest Group that was started at January's AAS meeting in Seattle at the request of that organization's Working Group on Astronomical Software, a Sloan-sponsored meeting at GitHub in San Francisco to begin work on a cohesive research software citation-enabling platform, the work of Force11 to "transform and improve" research communication, and WSSSPE's ongoing efforts that include software publication, citation, credit, and sustainability. Brief reports on these efforts were shared at the BoF, after which participants discussed ideas for improving software citation, generating a list of recommendations to the community of software authors, journal publishers, ADS, and research authors. The discussion, recommendations, and feedback will help form recommendations for software citation to those publishers...

    Full Text Available Objective – To test whether acquiring books written by authors of highly cited journal articles is an effective method for building a collection in the social sciences.Design – Comparison Study.Setting – Academic library at a public university in the US.Subjects – A total of 1,359 book titles, selected by traditional means (n=1,267 or based on citation analysis (n=92.Methods – The researchers identified highly‐ranked authors, defined as the most frequently cited authors publishing in journals with an impact factor greater than one, with no more than six journals in any category, using 1999 ISI data. They included authors in the categories Business, Anthropology, Criminology & Penology, Education & Education Research, Political Science, Psychology, Sociology/Anthropology, and General Social Sciences. The Books in Print bibliographic tool was searched to identify monographs published by these authors, and any titles not already owned were purchased. All books in the study were available to patrons by Fall 2005. The researchers collected circulation data in Spring 2007, and used it to compare titles acquired by this method with titles selected by traditional means.Main Results – Overall, books selected by traditional methods circulated more than those selected by citation analysis, with differences significant at the .001 level. However, at the subject category level, there was no significant difference at the .05 level. Most books selected by the test method circulated one to two times.Conclusion – Citation analysis can be an effective method for building a relevant book collection, and may be especially effective for identifying works relevant to a discipline beyond local context.

  20. Can "Hot Spots" in the Sciences Be Mapped Using the Dynamics of Aggregated Journal-Journal Citation Relations?

    NARCIS (Netherlands)

    Leydesdorff, L.; de Nooy, W.

    Using 3 years of the Journal Citation Reports (2011, 2012, and 2013), indicators of transitions in 2012 (between 2011 and 2013) were studied using methodologies based on entropy statistics. Changes can be indicated at the level of journals using the margin totals of entropy production along the row

  1. Is economics becoming the Mecca of Biology?: A citation analysis of the relationship between natural and social sciences

    OpenAIRE

    Yalcintas, Altug

    2012-01-01

    This essay argues that articles in economics, especially in the fields of evolutionary and institutional economics, are as much cited in biology as in economics. The citation analysis conducted in the essay suggests that economics is now becoming the Mecca of biology.

  2. Array Databases: Agile Analytics (not just) for the Earth Sciences

    Science.gov (United States)

    Baumann, P.; Misev, D.

    2015-12-01

    Gridded data, such as images, image timeseries, and climate datacubes, today are managed separately from the metadata, and with different, restricted retrieval capabilities. While databases are good at metadata modelled in tables, XML hierarchies, or RDF graphs, they traditionally do not support multi-dimensional arrays.This gap is being closed by Array Databases, pioneered by the scalable rasdaman ("raster data manager") array engine. Its declarative query language, rasql, extends SQL with array operators which are optimized and parallelized on server side. Installations can easily be mashed up securely, thereby enabling large-scale location-transparent query processing in federations. Domain experts value the integration with their commonly used tools leading to a quick learning curve.Earth, Space, and Life sciences, but also Social sciences as well as business have massive amounts of data and complex analysis challenges that are answered by rasdaman. As of today, rasdaman is mature and in operational use on hundreds of Terabytes of timeseries datacubes, with transparent query distribution across more than 1,000 nodes. Additionally, its concepts have shaped international Big Data standards in the field, including the forthcoming array extension to ISO SQL, many of which are supported by both open-source and commercial systems meantime. In the geo field, rasdaman is reference implementation for the Open Geospatial Consortium (OGC) Big Data standard, WCS, now also under adoption by ISO. Further, rasdaman is in the final stage of OSGeo incubation.In this contribution we present array queries a la rasdaman, describe the architecture and novel optimization and parallelization techniques introduced in 2015, and put this in context of the intercontinental EarthServer initiative which utilizes rasdaman for enabling agile analytics on Petascale datacubes.

  3. Latin American and Caribbean Countries in the Global Quest for World Class Academic Recognition: An Analysis of Publications in Scopus and the Science Citation Index between 1990 and 2010

    Directory of Open Access Journals (Sweden)

    Jorge Enrique Delgado

    2012-12-01

    Full Text Available The article investigates global participation in academic research productivity through the growth of publications from Latin America and the Caribbean (LA&C in two of the most prestigious bibliographic indexes, Scopus and the Science Citation Index (SCI. Data were obtained from the SCImago Journal and Country Rank and the Iberian-American and Inter-American Network of Science and Technology Indicators databases. Tables were created for the number of citable documents in Scopus, the publications in SCI, and the comparative indicators of the number of publications in SCI from LA&C countries adjusted for number of researchers, full-time researchers, inhabitants, and national research and development (R&D expenditure. The countries with the highest number of publications since 1990 SCI and 1996 Scopus were Brazil, Mexico, Argentina, and Chile. Colombia shows the largest growth in research productivity over the periods studied and became in 2010 the country with the fifth highest number of publications in both indexes. Comparative indicators adjusted for numbers of researchers, population and national R&D expenditures do not show clear differences in performance across countries. The article concludes with suggestions for the need to provide greater contextual analysis and including other bibliographic indexes and databases in order to have a fuller understanding of the reasons for particular levels of research productivity across LA&C countries.

  3. DPS Planetary Science Graduate Programs Database for Students and Advisors

    Science.gov (United States)

    Klassen, David R.; Roman, Anthony; Meinke, Bonnie K.

    2017-10-01

    Planetary science is a topic that covers an extremely diverse set of disciplines; planetary scientists are typically housed in a departments spanning a wide range of disciplines. As such it is difficult for undergraduate students to find programs that will give them a degree and research experience in our field as Department of Planetary Science is a rare sighting, indeed. Not only can this overwhelm even the most determined student, it can even be difficult for many undergraduate advisers.Because of this, the DPS Education committee decided several years ago that it should have an online resource that could help undergraduate students find graduate programs that could lead to a PhD with a focus in planetary science. It began in 2013 as a static page of information and evolved from there to a database-driven web site. Visitors can browse the entire list of programs or create a subset listing based on several filters. The site should be of use not only to undergraduates looking for programs, but also for advisers looking to help their students decide on their future plans. We present here a walk-through of the basic features as well as some usage statistics from the collected web site analytics. We ask for community feedback on additional features to make the system more usable for them. We also call upon those mentoring and advising undergraduates to use this resource, and for program admission chairs to continue to review their entry and provide us with the most up-to-date information.The URL for our site is http://dps.aas.org/education/graduate-schools.

  2. The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

    Science.gov (United States)

    Eyre-Walker, Adam; Stoletzki, Nina

    2013-10-01

    The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

  3. Citation classics in neuro-oncology: assessment of historical trends and scientific progress.

    Science.gov (United States)

    Hachem, Laureen D; Mansouri, Alireza; Juraschka, Kyle; Taslimi, Shervin; Pirouzmand, Farhad; Zadeh, Gelareh

    2017-09-01

    Citation classics represent the highest cited works in a field and are often regarded as the most influential literature. Analyzing thematic trends in citation classics across eras enables recognition of important historical advances within a field. We present the first analysis of the citation classics in neuro-oncology. The Web of Science database was searched using terms relevant to "neuro-oncology." Articles with >400 citations were identified and the top 100 cited articles were evaluated. The top 100 neuro-oncology citation classics consisted of 43 clinical studies (17 retrospective, 10 prospective, 16 randomized trials), 43 laboratory investigations, 8 reviews/meta-analyses, and 6 guidelines/consensus statements. Articles were classified into 4 themes: 13 pertained to tumor classification, 37 to tumor pathogenesis/clinical presentation, 6 to imaging, 44 to therapy (15 chemotherapy, 10 radiotherapy, 5 surgery, 14 new agents). Gliomas were the most common tumor type examined, with 70 articles. There was a significant increase in the number of citation classics in the late 1990s, which was paralleled by an increase in studies examining tumor pathogenesis, chemotherapy, and new agents along with laboratory and randomized studies. The majority of citation classics in neuro-oncology are related to gliomas and pertain to tumor pathogenesis and treatment. The rise in citation classics in recent years investigating tumor biology, new treatment agents, and chemotherapeutics may reflect increasing scientific interest in nonsurgical treatments for CNS tumors and the need for fundamental investigations into disease processes.

    Academic publications are important for developing a medical specialty or discipline and improvements of quality of care. As hospice palliative care medicine is a rapidly growing medical specialty in Taiwan, this study aimed to analyze the hospice palliative care-related publications from 1993 through 2013 both worldwide and in Taiwan, by using the Web of Science database. Academic articles published with topics including "hospice", "palliative care", "end of life care", and "terminal care" were retrieved and analyzed from the Web of Science database, which includes documents published in Science Citation Index-Expanded and Social Science Citation Indexed journals from 1993 to 2013. Compound annual growth rates (CAGRs) were calculated to evaluate the trends of publications. There were a total of 27,788 documents published worldwide during the years 1993 to 2013. The top five most prolific countries/areas with published documents were the United States (11,419 documents, 41.09%), England (3620 documents, 13.03%), Canada (2428 documents, 8.74%), Germany (1598 documents, 5.75%), and Australia (1580 documents, 5.69%). Three hundred and ten documents (1.12%) were published from Taiwan, which ranks second among Asian countries (after Japan, with 594 documents, 2.14%) and 16(th) in the world. During this 21-year period, the number of hospice palliative care-related article publications increased rapidly. The worldwide CAGR for hospice palliative care publications during 1993 through 2013 was 12.9%. As for Taiwan, the CAGR for publications during 1999 through 2013 was 19.4%. The majority of these documents were submitted from universities or hospitals affiliated to universities. The number of hospice palliative care-related publications increased rapidly from 1993 to 2013 in the world and in Taiwan; however, the number of publications from Taiwan is still far below those published in several other countries. Further research is needed to identify and try to reduce the

  20. Functions of Uni- and Multi-citations: Implications for Weighted Citation Analysis

    Directory of Open Access Journals (Sweden)

    Dangzhi Zhao

    2017-01-01

    Full Text Available Purpose: (1 To test basic assumptions underlying frequency-weighted citation analysis: (a Uni-citations correspond to citations that are nonessential to the citing papers; (b The influence of a cited paper on the citing paper increases with the frequency with which it is cited in the citing paper. (2 To explore the degree to which citation location may be used to help identify nonessential citations. Design/methodology/approach: Each of the in-text citations in all research articles published in Issue 1 of the Journal of the Association for Information Science and Technology (JASIST 2016 was manually classified into one of these five categories: Applied, Contrastive, Supportive, Reviewed, and Perfunctory. The distributions of citations at different in-text frequencies and in different locations in the text by these functions were analyzed. Findings: Filtering out nonessential citations before assigning weight is important for frequency-weighted citation analysis. For this purpose, removing citations by location is more effective than re-citation analysis that simply removes uni-citations. Removing all citation occurrences in the Background and Literature Review sections and uni-citations in the Introduction section appears to provide a good balance between filtration and error rates. Research limitations: This case study suffers from the limitation of scalability and generalizability. We took careful measures to reduce the impact of other limitations of the data collection approach used. Relying on the researcher’s judgment to attribute citation functions, this approach is unobtrusive but speculative, and can suffer from a low degree of confidence, thus creating reliability concerns. Practical implications: Weighted citation analysis promises to improve citation analysis for research evaluation, knowledge network analysis, knowledge representation, and information retrieval. The present study showed the importance of filtering out nonessential

  1. Do citation systems represent theories of truth?

    2001-01-01

    Full Text Available This article suggests that the citation can be viewed not only as a "concept symbol" but also as a "boundary object". The scientific, legal, and patent citation systems in America are examined at the micro, meso, and macro levels in order to understand how they function as commodified theories of truth in contemporary knowledge representation. This approach also offers a meta-theoretical overview of existing citation research efforts in science, law, and technology that may be of interdisciplinary interest.

  3. An approach for the condensed presentation of intuitive citation impact metrics which remain reliable with very few publications

    Energy Technology Data Exchange (ETDEWEB)

    2016-07-01

    An approach for presenting citation data in a condensed and intuitive manner which will allow for their reliable interpretation by policy analysts even in cases where the number of peer-reviewed publications produced by a given entity remains small is presented. The approach is described using country level data in Agronomy & Agriculture (2004–2013), an area of specialisation for many developing countries with a small output size. Four citation impact metrics, and a synthesis graph that we call the distributional micro-charts of relative citation counts, are considered in building our “preferred” presentation layout. These metrics include two indicators that have long been used by Science-Metrix in its bibliometric reports, the Average of Relative Citations (ARC) and the percentage of publications in the 10% most cited publications in the database (HCP), as well as two newer metrics, the Median of Relative Citations (MRC) and the Relative Integration Score (RIS). The findings reveal that the proposed approach combining the MRC and HCP with the distributional micro-charts effectively allows to better qualify the citation impact of entities in terms of central location, density of the upper citation tail and overall distribution than Science-Metrix former approach based on the ARC and HCP. This is especially true of cases with small population sizes where a strong presence of outliers (denoted by strong HCP scores) can have a significant effect on the central location of the citation data when estimated with an average.

  9. Careers of an elite cohort of U.S. basic life science postdoctoral fellows and the influence of their mentor's citation record.

    2010-11-15

    There is general agreement that the number of U.S. science PhDs being trained far exceeds the number of future academic positions. One suggested approach to this problem is to significantly reduce the number of PhD positions. A counter argument is that students are aware of the limited academic positions but have chosen a PhD track because it opens other, non-academic, opportunities. The latter view requires that students have objective information about what careers options will be available for them. The scientific careers of the 1992-94 cohort of NIH National Institute of General Medical Sciences (NIGMS) Kirchstein-NRSA F32 postdoctoral fellows (PD) was determined by following their publications (PubMed), grants (NIH and NSF), and faculty and industry positions through 2009. These basic life science PDs receive support through individual grant applications and represent the most successful class of NIH PDs as judged by academic careers and grants. The sex dependence of the career and grant success and the influence of the PD mentor's citation record were also determined Of the 439 1992-94 NIGMS F32 fellows, the careers of 417 could be determined. Although females had significantly higher rates of dropping out of science (22% females, 9% males) there was no significant difference in the fraction of females that ended up as associate or full professors at research universities (22.8% females, 29.1% for males). More males then females ended up in industry (34% males, 22% females). Although there was no significant correlation between male grant success and their mentor's publication record (h index, citations, publications), there was a significant correlation for females. Females whose mentor's h index was in the top quartile were nearly 3 times as likely to receive a major grant as those whose mentors were in the bottom quartile (38.7% versus 13.3%). Sixteen years after starting their PD, only 9% of males had dropped out of science. More females (28%) have

  14. Citation analysis may severely underestimate the impact of clinical research as compared to basic research.

    Citation analysis has become an important tool for research performance assessment in the medical sciences. However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. A visualization methodology is introduced that reveals differences in citation practices between medical research areas. The methodology extracts terms from the titles and abstracts of a large collection of publications and uses these terms to visualize the structure of a medical field and to indicate how research areas within this field differ from each other in their average citation impact. Visualizations are provided for 32 medical fields, defined based on journal subject categories in the Web of Science database. The analysis focuses on three fields: Cardiac & cardiovascular systems, Clinical neurology, and Surgery. In each of these fields, there turn out to be large differences in citation practices between research areas. Low-impact research areas tend to focus on clinical intervention research, while high-impact research areas are often more oriented on basic and diagnostic research. Popular bibliometric indicators, such as the h-index and the impact factor, do not correct for differences in citation practices between medical fields. These indicators therefore cannot be used to make accurate between-field comparisons. More sophisticated bibliometric indicators do correct for field differences but still fail to take into account within-field heterogeneity in citation practices. As a consequence, the citation impact of clinical intervention research may be substantially underestimated in comparison with basic and diagnostic research.

    A bibliometric study was carried out to describe the scientific production on cancer written by Peruvians and published in international health journals, as well as to assess the scientific collaboration networks. It included articles on cancer written in Peru between the years 2000 and 2011 and published in health journals indexed in SCOPUS or Science Citation Index Expanded. In the 358 articles identified, an increase in the production was seen, from 4 articles in 2000 to 57 in 2011.The most studied types were cervical cancer (77 publications); breast cancer (53), and gastric cancer (37). The National Institute of Neoplastic Diseases (INEN) was the most productive institution (121 articles) and had the highest number of collaborations (180 different institutions). 52 clinical trials were identified, 29 of which had at least one author from INEN. We can conclude that, cancer research is increasing in Peru, the INEN being the most productive institution, with an important participation in clinical trials.

    The monosialoganglioside (GM1) is a popular topic of research but the bibliometric analysis of GM1 over the decades in Science Citation Index-Expanded (SCI-E) remains poorly understood. To identify the global research and to improve the understanding of research trends in the GM1 field from 1942 to 2011. A bibliometric study. We performed a bibliometric analysis based on the SCI-E published by the Institute of Scientific Information. Articles closely related to GM1 were included. Exclusive criteria: (1) Articles related to gangliosidosis, disialo-ganglioside, trisialo-ganglioside or ganglioside GQIb. (2) Document types such as meeting abstracts, reviews, proceedings papers, notes, and letters. (1) Type of publication output; (2) number of author outputs; (3) distribution of output in subject categories; (4) publication distribution of countries; (5) distribution of output in journals, and (6) distribution of citations in each decade. During 1942 to 2011, there were 10 126 papers on GM1 that were added to the SCI. Articles (8 004) were the most frequently used document type comprising 79.0%, followed by meeting abstracts, reviews and proceedings papers. Research on GM1 could be found in the SCI from 1942, it was developed in the 1970s, greatly increased in the 1980s, and reached a peak in the 1990s, and it was slightly decreased in 2000. The distribution of subject categories showed that GM1 research covered both clinical and basic science research. The USA, Japan, and Germany were the three most productive countries, and the publication numbers in the USA were highest in all decades. The Journal of Biological Chemistry, Journal of Neurochemistry and Biochemistry were core subject journals in GM1 studies in each decade. This study highlights the topics in GM1 research that are being published around the world.

    Ghiasi, G.; Lariviere, V.; Sugimoto, C.

    2016-07-01

    Citation rates are increasingly used as a currency of science, providing a basis to reward a scientist. Self-citations, an inevitable part of scholarly communication, may contribute to the inflation of citation counts and impose a considerable impact on research evaluation and academic career advancements. Self-citations are classified into two types in this study: synchronous self-citations (self-citations an author gives) and diachronous self-citations (selfcitations an author receives). The main objective of this paper is to provide a comprehensive gendered analysis of synchronous and diachronous self-citations across all scientific disciplines. For this purpose, citation data of 12,725,171 articles published in 2008-2014 are extracted from Web of Science and are further scrutinized for articles of each gender. The findings reveal that men receive citations from their own papers at a higher rate than their women counterparts. They also tend to give more citations to their own publications. Gender gap in citation impact decreases when first-author’s diachronous citations are eliminated in the impact analysis. However, the gap does not vary when all-authors’ diachronous citations are excluded. The results of this research is important for effective gender-related policy-making in the science and technology arena. (Author)

  8. A reverse engineering approach to the suppression of citation biases reveals universal properties of citation distributions.

    Science.gov (United States)

    Radicchi, Filippo; Castellano, Claudio

    2012-01-01

    The large amount of information contained in bibliographic databases has recently boosted the use of citations, and other indicators based on citation numbers, as tools for the quantitative assessment of scientific research. Citations counts are often interpreted as proxies for the scientific influence of papers, journals, scholars, and institutions. However, a rigorous and scientifically grounded methodology for a correct use of citation counts is still missing. In particular, cross-disciplinary comparisons in terms of raw citation counts systematically favors scientific disciplines with higher citation and publication rates. Here we perform an exhaustive study of the citation patterns of millions of papers, and derive a simple transformation of citation counts able to suppress the disproportionate citation counts among scientific domains. We find that the transformation is well described by a power-law function, and that the parameter values of the transformation are typical features of each scientific discipline. Universal properties of citation patterns descend therefore from the fact that citation distributions for papers in a specific field are all part of the same family of univariate distributions.

    Full Text Available Databases are deeply embedded in archaeology, underpinning and supporting many aspects of the subject. However, as well as providing a means for storing, retrieving and modifying data, databases themselves must be a result of a detailed analysis and design process. This article looks at this process, and shows how the characteristics of data models affect the process of database design and implementation. The impact of the Internet on the development of databases is examined, and the article concludes with a discussion of a range of issues associated with the recording and management of archaeological data.

    Acute appendicitis is one of the most commonly encountered emergency surgical conditions. An understanding of the most highly cited research works in this field is key to good evidence based clinical practice. To perform a bibliometric analysis on the 100 most frequently cited articles in the field of acute appendicitis. The database of the Institute for Scientific Information (ISI) Web of Science Expanded citation index was searched to identify the 100 most frequently cited articles in the field of acute appendicitis. The web of science expanded citation index tracks article citations made since 1946. The top 100 most frequently cited articles were selected for analysis in this series. The most frequently cited article was cited 649 times and the least cited three article 93 times. The average number of citations per article was 167.74. The top 100 cited articles originated from 17 countries. Over half of the papers originated from the USA. Fifty-one of the papers concentrated on diagnostics of acute appendicitis. Thirty-six papers looked at the treatment of acute appendicitis with 30 of these dealing with the surgical management of the disease. There were 6 studies at level 1a, 20 studies at level 1b and 43,5,17 and 9 studies at levels 2, 3, 4 and 5 respectively. Bibliometric analysis of the citation classics in a given field can provide interesting insights into the relationship between the quality of research outputs and clinical practice. The study of acute appendicitis remains an active field of research with a growing body of higher quality evidence underpinning our clinical practice.

    To identify and analyze the characteristics of the most influential articles about central nervous system (CNS) inflammatory demyelinating disease. The Institute for Scientific Information (ISI) Web of Science database and the 2014 Journal Citation Reports Science Edition were used to retrieve the top 100 cited articles on CNS inflammatory demyelinating disease. The citation numbers, journals, years of publication, authorships, article types, subjects and main issues were analyzed. For neuromyelitis optica (NMO), articles that were cited more than 100 times were regarded as a citation classic and described separately. The top 100 cited articles were published between 1972 and 2011 in 13 journals. The highest number of articles (n = 24) was published in Brain, followed by The New England Journal of Medicine (n = 21). The average number of citations was 664 (range 330-3,897), and 64% of the articles were from the United States and the United Kingdom. The majority of the top 100 cited articles were related to multiple sclerosis (n = 87), and only a few articles reported on other topics such as NMO (n = 9), acute disseminated encephalomyelitis (n = 2) and optic neuritis (n = 2). Among the top 100 cited articles, 77% were original articles. Forty-one citation classics were found for NMO. Our study provides a historical perspective on the research progress on CNS inflammatory demyelinating disease and may serve as a guide for important advances and trends in the field for associated researchers.

    Full Text Available 論文被引用次數常被用為評估學術研究成果的指標,其對學術界的重要性不言可喻。為求公允,引用次數的運算宜力求正確,然而,由於提供查詢論文被引用次數之系統,因發展背景不同,系統的資料處理程序與原則有別,使得各篇論文的被引用次數在不同系統之檢索結果因而產生差異。本研究除藉由文獻探討外,選擇淡江大學工學院獲得校內研究獎助之學術論文372篇,以Science Citation Index Expanded(簡稱SCIE)與Scopus為對象,透過實際檢索,比較分析兩者計算論文被引用次數存在的現象與問題,以歸納影響因素。研究結果發現在比較SCIE與Scopus兩者的收錄範圍時,除資料種數外,應一併考量其收錄的資料類型與政策等面向。此外,其著錄參考文獻的規範不一,書目記錄品質的控管、引用與被引用文獻連結的處理機制等亦存在相異的作法,因而影響同一篇文獻卻有不同的被引用次數之檢索結果。由此可知,系統收錄資料的範圍、參考文獻著錄之完整性、書目記錄的品質以及文獻連結機制等情況,都是影響論文被引用次數計算之因素。Citedness score is a widely accepted metric for the quality of scholarly literatures, therefore, the forming calculation and corresponsive consequence of citation counts becomes of importance for academic researchers, especially for the research assessment. However, the distinction of citedness score exists in heterogeneous information systems resulted from considerations for system construction and development, such as purpose, procedure and policy of data processing, and that would bring various meanings and impacts for citedness score. This paper aims to examine the distinctive factors and results on calculation of citedness score of scholarly literatures between Science Citation Index Expanded and Scopus by adoption of

  1. Using XML technology for the ontology-based semantic integration of life science databases.

    Science.gov (United States)

    Philippi, Stephan; Köhler, Jacob

    2004-06-01

    Several hundred internet accessible life science databases with constantly growing contents and varying areas of specialization are publicly available via the internet. Database integration, consequently, is a fundamental prerequisite to be able to answer complex biological questions. Due to the presence of syntactic, schematic, and semantic heterogeneities, large scale database integration at present takes considerable efforts. As there is a growing apprehension of extensible markup language (XML) as a means for data exchange in the life sciences, this article focuses on the impact of XML technology on database integration in this area. In detail, a general architecture for ontology-driven data integration based on XML technology is introduced, which overcomes some of the traditional problems in this area. As a proof of concept, a prototypical implementation of this architecture based on a native XML database and an expert system shell is described for the realization of a real world integration scenario.

    Full Text Available Brazil is going through a time of reflection about the preservation of natural resources, an issue that is increasingly considered in its agenda. The search for balance between environmental, social and economic aspects has been a challenge for business survival over the years and has led companies to adopt initiatives focused on sustainability. The objective of this article is to analyse how the international scientific production addresses sustainable practices and initiatives and their relationship with organizational performance. Considering this scope, a bibliometric study of the publications located on Web of Science - Social Sciences Citation Index (WoS-SSCI was developed. There were 33 articles identified and selected on the subject. Journals that stand out in quantity of articles and number of citations are the Journal of Cleaner Production and Strategic Management Journal, respectively. Analysing the results, a growing concern about this issue and the increase in publications was noticed after the 2000s. The results found, in general, associate sustainable practices to positive organizational performance, such as increased profit on the product sold, quality improvement, improved reputation, and waste reduction, among others gains identified.

Keywords in English, Spanish, Italian and German, truncated terms (such as ‘bienn’, single letters (such as P, and numbers were combined to retrieve all possible citations. Additional filters to exclude citations to publications other than proceedings were applied to the P search results, which had accounted for 75% of the total results. The references remaining in the P search set were validated using Google Scholar and WorldCat. Finally, two random samples of 1,000 references were checked manually to determine the extent of false positives and false negatives in the results.Main Results – The study’s findings are presented for NSE and SSH separately, with 1.7% of NSE citations and 2.5% of SSH citations referring to conference proceedings. The total number of citations to proceedings has increased over the period 1980-2005, however, citations to proceedings in NSE and SSH as a proportion of all citations decreased during this time. A small increase in the average number of proceedings citations per paper was found for NSE and SSH. When this increase is compared to the overall increase in references per paper over this period, the share of proceedings citations per paper has decreased. Of all fields in NSE and SSH, only engineering has increased the proportion of proceedings citations, rising from 7% to 10% in the period studied. In 2005, the share of proceedings

    2017-08-07

    The recent publication of a commentary article by Dadkhah et al. (J Cell Commun Signal 11:181-185, 2017) which addressed issues raised by the citation of questionable scientific papers in current databases and the recent retraction of manuscripts dealing with the biological properties of the CCN1 protein by Lin et al. (J Biol Chem 291(53):27433, 2016) prompted us to examine how this situation reflects an evolution of the original citation system, endangering scientific communication. We argue that the increasing number of publication retractions that have been witnessed over several years is a direct consequence of the bias created by the inconsistency of citation metrics.

    2010-09-01

    To describe the Peruvian scientific production in indexed journals in the Institute for Scientific Information (ISI) and the characteristics of the institutional collaborative networks. All papers published in the ISI database (Clinical Medicine collection) were included during 2000 to 2009 with at least one author with a Peruvian affiliation. The publication trend, address of corresponding author, type of article, institution, city (only for Peru), and country were evaluated. The collaborative networks were analized using the Pajek® software. 1210 papers were found, increasing from 61 in 2000 to 200 in 2009 (average of 121 articles/year). 30.4% articles included a corresponding author from a Peruvian institution. The average of authors per article was 8.3. Original articles represented 82.1% of total articles. Infectious diseases-related journals concentrated most of the articles. The main countries that collaborate with Peru are: USA (60.4%), England (12.9%), and Brazil (8.0%). Lima concentrated 94.7% of the publications and three regions (Huancavelica, Moquegua and Tacna) did not register any publication. Only two universities published more than one article/year and four institutions published more than 10 articles/year. Universidad Peruana Cayetano Heredia published 45% of the total number of articles, being the most productive institution and which concentrated the most number of collaborations with foreign institutions. The ministry of Health--including all dependencies--published 37.3% of the total number of publications. There is a higher level of collaboration with foreign institutions rather than local institutions. The Peruvian scientific production in medicine represented in the ISI database is very low but growing, and is concentrated in Lima and in a few institutions. The most productive Peruvian institutions collaborate more intensively with foreign journals rather than local institutions.

  16. High Citation of Iranian Coauthored articles in comparison with single authored ones: does it link with self-citation

    Directory of Open Access Journals (Sweden)

    Seaid Nazarian

    2012-10-01

    Full Text Available The aim of this research was to investigate the effect of co-authorship and self-citation on the citation rates of Iranian indexed articles in Web of Science (WoS. Research population included Iranian indexed articles in WoS in 2007 which had been received at least one citation. Numbers of articles in the time of research (October & November 2010 was 7355, which 390 of them, using stratified random sampling, was selected as sample. Research results showed that co-authored articles have received more citations than single-authored ones and this difference was statistically significant. On the other hand, self-citation exclusion has significantly reduced the citation rates of both co-authored and single-authored articles. After self-citation exclusion, existing difference between citation rates of co-authored and single-authored articles lost its significance. So, it can be concluded that self-citation exclusion led to reduction of citation rates of Iranian indexed articles in WoS, but this exclusion affected co-authored articles citation rates more than single-authored ones. In other words, high citation of Iranian co-authored articles in comparison with single-authored articles has been affected mainly by self-citation, not by foreign citation. This finding, which was our contribution, contradicted with results of previous researches.

  17. Nonuniversal power law scaling in the probability distribution of scientific citations.

    Science.gov (United States)

    Peterson, George J; Pressé, Steve; Dill, Ken A

    2010-09-14

    We develop a model for the distribution of scientific citations. The model involves a dual mechanism: in the direct mechanism, the author of a new paper finds an old paper A and cites it. In the indirect mechanism, the author of a new paper finds an old paper A only via the reference list of a newer intermediary paper B, which has previously cited A. By comparison to citation databases, we find that papers having few citations are cited mainly by the direct mechanism. Papers already having many citations ("classics") are cited mainly by the indirect mechanism. The indirect mechanism gives a power-law tail. The "tipping point" at which a paper becomes a classic is about 25 citations for papers published in the Institute for Scientific Information (ISI) Web of Science database in 1981, 31 for Physical Review D papers published from 1975-1994, and 37 for all publications from a list of high h-index chemists assembled in 2007. The power-law exponent is not universal. Individuals who are highly cited have a systematically smaller exponent than individuals who are less cited.

    Efficient and effective information retrieval in life sciences is one of the most pressing challenge in bioinformatics. The incredible growth of life science databases to a vast network of interconnected information systems is to the same extent a big challenge and a great chance for life science research. The knowledge found in the Web, in particular in life-science databases, are a valuable major resource. In order to bring it to the scientist desktop, it is essential to have well performing search engines. Thereby, not the response time nor the number of results is important. The most crucial factor for millions of query results is the relevance ranking. In this paper, we present a feature model for relevance ranking in life science databases and its implementation in the LAILAPS search engine. Motivated by the observation of user behavior during their inspection of search engine result, we condensed a set of 9 relevance discriminating features. These features are intuitively used by scientists, who briefly screen database entries for potential relevance. The features are both sufficient to estimate the potential relevance, and efficiently quantifiable. The derivation of a relevance prediction function that computes the relevance from this features constitutes a regression problem. To solve this problem, we used artificial neural networks that have been trained with a reference set of relevant database entries for 19 protein queries. Supporting a flexible text index and a simple data import format, this concepts are implemented in the LAILAPS search engine. It can easily be used both as search engine for comprehensive integrated life science databases and for small in-house project databases. LAILAPS is publicly available for SWISSPROT data at http://lailaps.ipk-gatersleben.de.

    Full Text Available Objective – To investigate the citation performance of open access (OA and toll access (TA papers published in author-pays open access journals. Design – Longitudinal citation analysis. Setting – Publications in Springer and Elsevier’s author-pays open access journals. Subjects – 633 journals published using the author-pays model. This model encompasses both journals where the article processing charge (APC is required and journals in which authors can request open access and voluntarily pay APCs for accepted manuscripts. Methods – The authors identified APC funded journals (journals funded by mandatory author processing charges as well as those where authors voluntarily paid a fee in order to have their articles openly accessible from both Springer and Elsevier, and analyzed papers published in these journals from 2007 to 2011. The authors excluded journals that adopted the APC model later than 2007. To identify Springer titles, the authors created a search strategy to identify open access articles in SpringerLink. A total of 576 journals were identified and double checked in the Sherpa-Romeo database (a database of copyright and open access self-archiving policies of academic journals to verify their open access policies. The authors then downloaded the journal content using SpringerLink, and using Springer Author-Mapper, separated out the open access articles from the toll access articles. In order to identify the Elsevier APC funded journals, the authors referred to “Open Access Journal Directory: A-Z,” which contained 35 OA journals (p. 584. Once the authors consulted “Sponsored articles” issued by Elsevier and verified titles in Sherpa-Romeo, they identified 57 journals that fit the “author-pays” model. The bibliographic information was downloaded and OA articles were separated from TA articles. The authors confirmed that all journals were indeed OA publications by downloading the full-text from off-campus locations

    2012-03-01

    The first part of the paper deals with the assessment of international databases in relation to the number of historical publications (representation and relevance in comparison with the model database). The second part is focused on providing answer to the question whether historiography is governed by similar bibliometric rules as exact sciences or whether it has its own specific character. Empirical database for this part of the research constituted the database prepared ad hoc: The Citation Index of the History of Polish Media (CIHPM). Among numerous typically historical features the main focus was put on: linguistic localism, specific character of publishing forms, differences in citing of various sources (contributions and syntheses) and specific character of the authorship (the Lorenz Curve and the Lotka's Law). Slightly more attention was devoted to the half-life indicator and its role in a diachronic study of a scientific field; also, a new indicator (HL14), depicting distribution of citations younger then half-life was introduced. Additionally, the comparison and correlation of selected parameters for the body of historical science (citations, HL14, the Hirsch Index, number of publications, volume and other) were also conducted.

    Conclusion: The presence of correlation between citations and bookmarks implies that bookmarks can represent article's scientific impact. However, according to the weakness of this correlation, replacing these two indicators is not recommended the bookmarking data can be used as a supplementary metric in research evaluation and assessment of scientific impact. Bookmarked articles in comparison with those unbookmarked have been shown higher mean citation which reflect user's selectivity in article bookmarking and represent another aspect of altmetrics validity.

    To quantify the impact factor of Anales Españoles de Pediatría from 1997 until 2000 and to identify the journal's citation patterns and the topics with the greatest impact. SCISEARCH was used to locate citations of articles published in Anales Españoles de Pediatría between 1995 and 1999. The following data were collected for each article: year of publication, authors, journal, country of publication, language, specialty or specialties, institution(s), residence of the first author and topic. The impact factor was calculated as the ratio between citations received over 1 year by articles published in Anales Españoles de Pediatría in the two previous years and the total number of articles published by Anales Españoles de Pediatría over the 2 years under study. The impact factor of Anales Españoles de Pediatría was 0.052 in 1997, 0.080 in 1998, 0.101 in 1999, 0.089 in 2000 and 0.064 in 2001. Citations were found in a wide range of source journals. The greatest proportion (35.6 %) were found in Spanish medical journals. Citations were made mainly by Spanish authors (62.8 %) and self-citation was moderate (14.3 %). Topics related to neurology (16.9 % of the citations received), infectious diseases (16.2 %) and neonatology (14.8 %) had the greatest impact. The impact factor of Anales Españoles de Pediatria is modest, although higher than that of some other biomedical publications included in Journal Citation Reports.

    Full Text Available This year marked the twentieth anniversary of the Korean Association of Medical Journal Editors (KAMJE. The number of member journals has increased from 105 to 257 since its inception in 1996. In the same period, the number of journals listed in the Science Citation Index Expanded (SCIE has increased from zero to 35. The average journal impact factor (JIF that was initially 0.13 has now increased by more than tenfold on average to 1.45 as of 2014. Many KAMJE journals that are not indexed in the SCIE are putting their best effort towards eventual inclusion. Following listing with SCIE, however, editors have turned their attention towards the JIF and have shown interest in early online publication as a means of improving the JIF. The current status of PubMed electronic publication ahead of print (EAP was surveyed among KAMJE journals that are indexed in the SCIE, and the impact of this EAP on the improvement of the JIF was investigated. Based on the survey, more than half of the members have started or are planning on implementing EAP. However, these efforts were found to be still in their infancy, and they have been insufficient to serve as a basis for scientific analysis. Since the sample size is too small and the implementation period too short to statistically analyze the effects of early publication on the JIF, a case-by-case approach was taken. Based on case studies, it is difficult to draw conclusions yet about whether online early publication enhances the JIF.

  19. Open-access databases as unprecedented resources and drivers of cultural change in fisheries science

    Energy Technology Data Exchange (ETDEWEB)

    2014-01-01

    Open-access databases with utility in fisheries science have grown exponentially in quantity and scope over the past decade, with profound impacts to our discipline. The management, distillation, and sharing of an exponentially growing stream of open-access data represents several fundamental challenges in fisheries science. Many of the currently available open-access resources may not be universally known among fisheries scientists. We therefore introduce many national- and global-scale open-access databases with applications in fisheries science and provide an example of how they can be harnessed to perform valuable analyses without additional field efforts. We also discuss how the development, maintenance, and utilization of open-access data are likely to pose technical, financial, and educational challenges to fisheries scientists. Such cultural implications that will coincide with the rapidly increasing availability of free data should compel the American Fisheries Society to actively address these problems now to help ease the forthcoming cultural transition.

    Author self-citation contributes to the overall citation count of an article and the impact factor of the journal in which it appears. Little is known, however, about the extent of self-citation in the general clinical medicine literature. The objective of this study was to determine the extent and temporal pattern of author self-citation and the article characteristics associated with author self-citation. We performed a retrospective cohort study of articles published in three high impact general medical journals (JAMA, Lancet, and New England Journal of Medicine) between October 1, 1999 and March 31, 2000. We retrieved the number and percentage of author self-citations received by the article since publication, as of June 2008, from the Scopus citation database. Several article characteristics were extracted by two blinded, independent reviewers for each article in the cohort and analyzed in multivariable linear regression analyses. Since publication, author self-citations accounted for 6.5% (95% confidence interval 6.3-6.7%) of all citations received by the 328 articles in our sample. Self-citation peaked in 2002, declining annually thereafter. Studies with more authors, in cardiovascular medicine or infectious disease, and with smaller sample size were associated with more author self-citations and higher percentage of author self-citation (all p≤0.01). Approximately 1 in 15 citations of articles in high-profile general medicine journals are author self-citations. Self-citation peaks within about 2 years of publication and disproportionately affects impact factor. Studies most vulnerable to this effect are those with more authors, small sample size, and in cardiovascular medicine or infectious disease.

  1. Using News Media Databases (LexisNexis) To Identify Relevant Topics For Introductory Earth Science Classes

    2003-12-01

    Introductory Earth science courses are undergoing pedagogical changes in universities across the country and are focusing more than ever on the non-science majors. Increasing enrollment of non-science majors in these introductory Earth science courses demands a new look at what is being taught and how the content can be objectively chosen. Assessing the content and effectiveness of these courses requires a quantitative investigation of introductory Earth science topics and their relevance to current issues and concerns. Relevance of Earth science topics can be linked to improved students' attitude toward science and a deeper understanding of concepts. We have used the Internet based national news search-engine LexisNexis Academic Universe (http://www.lexisnexis.org/) to select the occurrence of Earth science terms over the last 12 months, five and ten years both regionally and nationally. This database of term occurrences is being used to examine how Earth sciences have evolved in the news through the last 10 years and is also compared with textbook contents and course syllabi from randomly selected introductory earth science courses across the nation. These data constitute the quantitative foundation for this study and are being used to evaluate the relevance of introductory earth science course content. The relevance of introductory course content and current real-world issues to student attitudes is a crucial factor when considering changes in course curricula and pedagogy. We have examined students' conception of the nature of science and attitudes towards science and learning science using a Likert-scale assessment instrument in the fall 2002 Geology 100 classes at Iowa State University. A pre-test and post-test were administered to see if the students' attitudes changed during the semester using as reference a control group comprised of geoscience undergraduate and graduate students, and faculty. The results of the attitude survey have been analyzed in terms

  2. Homophily and missing links in citation networks

    2015-01-01

    Citation networks have been widely used to study the evolution of science through the lenses of the underlying patterns of knowledge flows among academic papers, authors, research sub-fields, and scientific journals. Here we focus on citation networks to cast light on the salience of homophily, namely the principle that similarity breeds connection, for knowledge transfer between papers. To this end, we assess the degree to which citations tend to occur between papers that are concerned with seemingly related topics or research problems. Drawing on a large data set of articles published in the journals of the American Physical Society between 1893 and 2009, we propose a novel method for measuring the similarity between articles through the statistical validation of the overlap between their bibliographies. Results suggest that the probability of a citation made by one article to another is indeed an increasing function of the similarity between the two articles. Our study also enables us to uncover missing ci...

    Full Text Available The present study endeavored to analysis the scientific publications that were indexed in the Web of Science database as the information management records and the visualization of science structure in this field during 1988-2009. The research method was scientometrics. During the study period, 1120 records in the field of information management have been published. These records were extracted in the form of plain text files and stored in a PC. Then they were analyzed by ISI.exe and HistCite softwares. Author's coefficient collaboration (CC was grown from zero in 1988 to 0.33 in 2009. Average coefficient collaboration between the authors was 0.22 which confirmed low authors collaboration in this area. The records have been published in 63 languages. Among these records the English language with 93.8 % possessed the highest proportion. City University London and the University of Sheffield in England had the most common publications in information management field. Based on the number of published records, T.D. Wilson with 13 records and 13 citations ranked as the first. The average number of global citations to 112 documents has been equal to 8.78. Despite the participation of different countries in the production of documents, more than 28.9% of records have been produced in the United States. According to results, 10 countries have published more than 72.4 percent of the records. City University London and the University of Sheffield have had highest frequency in this area. 15 journals have published 564 records (50.4% of the total productions.

    2013-06-01

    The citation analysis of the research output of the German economic research institutes presented here is based on publications in peer-reviewed journals listed in the Social Science Citation Index for the 2000-2009 period. The novel feature of the paper is that a count data model quantifies the determinants of citation success and simulates their citation potential. Among the determinants of the number of cites the quality of the publication outlet exhibits a strong positive effect. The same effect has the number of the published pages, but journals with size limits also yield more cites. Field journals get less citations in comparison to general journals. Controlling for journal quality, the number of co-authors of a paper has no effect, but it is positive when co-authors are located outside the own institution. We find that the potential citations predicted by our best model lead to different rankings across the institutes than current citations indicating structural change.

    Structured databases of chemical and physical properties play a central role in the everyday research activities of scientists and engineers. In materials science, researchers and engineers turn to these databases to quickly query, compare, and aggregate various properties, thereby allowing for the development or application of new materials. The vast majority of these databases have been generated manually, through decades of labor-intensive harvesting of information from the literature; yet, while there are many examples of commonly used databases, a significant number of important properties remain locked within the tables, figures, and text of publications. The question addressed in our work is whether, and to what extent, the process of data collection can be automated. Students of the physical sciences and engineering are often confronted with the challenge of finding and applying property data from the literature, and a central aspect of their education is to develop the critical skills needed to identify such data and discern their meaning or validity. To address shortcomings associated with automated information extraction, while simultaneously preparing the next generation of scientists for their future endeavors, we developed a novel course-based approach in which students develop skills in polymer chemistry and physics and apply their knowledge by assisting with the semi-automated creation of a thermodynamic property database.

    Full Text Available Bibliometric analyses based on citations are most often at the forefront where scientific publications are concerned. A fact often neglected is that the visibility and availability of scientific publications are basic prerequisites for future reading, citation and influence. Journal visibility can be significantly improved by providing open access and availability through popular online databases. In this study, we investigated 112 mapping science journals to determine the visibility of scientific publications in a smaller interdisciplinary field. In addition to other data, we collected data on open access, indexing, subject areas within the Web of Science and Scopus bibliographic databases and the number of journals in these databases. The coverage of mapping science journals in 14 bibliographic databases was analyzed. Only 11% of the titles from the journals analyzed were indexed in 10 or more databases. Google Scholar, Scopus, Bibliotheca Cartographica and GEOBASE include most mapping science journals, while only 19 are included in Web of Science. A comparison indicates more thorough coverage of an individual journal in Web of Science than in Scopus. Only a few mapping science journals appear in the Directory of Open Access Journals, despite the large number of open access mapping science journals available. Adding subject categories within databases does not facilitate finding mapping science journals, which are dispersed among numerous, mostly inadequate categories in the Web of Science and Scopus databases.

    The number of citations that an article has received can be used to evaluate its impact on the scientific community. This study aimed to identify the 100 most cited articles in the field of neurointervention and to analyze their characteristics. We selected the 669 journals that were considered potentially to publish neurointervention articles based on the database of Journal Citation Reports. Using the Web of Science citation search tool, we identified the 100 most cited articles relevant to neurointervention within the selected journals. Each article was evaluated for several characteristics including publication year, journal, journal category, impact factor, number of citations, number of citations per year, authorship, department, institution, country, type of article, and topic. The number of citations for the top 100 articles ranged from 1912 to 170 (mean 363.4) and citations per year ranged from 271.0 to 4.1 (mean 40.0). The majority of articles were published in clinical neurology journals (63%), were published in 2000-2009 (39%), originated in the USA (45%), were original articles (95%), and dealt with endovascular treatment of cerebral aneurysm (42%). The Department of Radiology, University of California School of Medicine (n=12) was the leading institution and Viñuela F (n=11) was the most prolific author. Our study presents a detailed list and analysis of the 100 most cited articles in the field of neurointervention and provides a historical perspective on the scientific progress in this field.

    Measures of research productivity are increasingly used to determine how research should be evaluated and funding decisions made. In psychiatry, citation patterns within and between countries are not known, and whether these differ by choice of citation metric. In this study, we examined publication characteristics and citation practices in articles published in 50 Web of Science indexed psychiatric and relevant clinical neurosciences journals, between January 2004 and December 2009 comprising 51,072 records that produced 375,962 citations. We compared citation patterns, including self-citations, between countries using standard x(2) tests. We found that most publications came from the USA, with Germany being second and UK third in productivity. USA articles received most citations and the highest citation rate with an average 11.5 citations per article. The UK received the second highest absolute number of citations, but came fourth by citation rate (9.7 citations/article), after the Netherlands (11.4 citations/article) and Canada (9.8 citations/article). Within the USA, Harvard University published most articles and these articles were the most cited, on average 20.0 citations per paper. In Europe, UK institutions published and were cited most often. The Institute of Psychiatry/Kings College London was the leading institution in terms of number of published records and overall citations, while Oxford University had the highest citation rate (18.5 citations/record). There were no differences between the self-citation practices of American and European researchers. Articles that examined some aspect of treatment in psychiatry were the most published. In terms of diagnosis, papers about schizophrenia-spectrum disorders were the most published and the most cited. We found large differences between and within countries in terms of their research productivity in psychiatry and clinical neuroscience. In addition, the ranking of countries and institutions differed widely

    2011-01-01

    Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the "boosting effect" of landmark papers, our analysis reveals how new ideas and new players can make their...

    The use of RDBMS for the storage and management of geo and space science data and/or metadata is very common. Although the information stored in tables is based on a data model and therefore well organized and structured, a direct mashup with RDF based data stored in triple stores is not possible. One solution of the problem consists in the transformation of the whole content into RDF structures and storage in triple stores. Another interesting way is the use of a specific system/service, such as e.g. D2RQ, for the access to relational database content as virtual, read only RDF graphs. The Semantic Web based -proof of concept- GFZ ISDC uses the triple store Virtuoso for the storage of general context information/metadata to geo and space science satellite and ground station data. There is information about projects, platforms, instruments, persons, product types, etc. available but no detailed metadata about the data granuals itself. Such important information, as e.g. start or end time or the detailed spatial coverage of a single measurement is stored in RDBMS tables of the ISDC catalog system only. In order to provide a seamless access to all available information about the granuals/data products a mashup of the different data resources (triple store and RDBMS) is necessary. This paper describes the use of D2RQ for a Semantic Web/SPARQL based mashup of relational databases used for ISDC data server but also for the access to IUGONET and/or ESPAS and further geo and space science data resources.

    The objective of this project is to construct the bibliographic information database and the web directory in the nuclear field. Its construction is very timely and important. Because nuclear science and technology has an considerable effect all over the other sciences and technologies due to its property of giant and complex engineering. We aimed to firmly build up a basis of efficient management of the bibliographic information database and the web directory in the nuclear field. The results of this project that we achieved in this year are as follows : first, construction of the bibliographic information database in the nuclear field(the target title: 1,500 titles ; research report: 1,000 titles, full-text report: 250 titles, full-text article: 250 titles). Second, completion of construction of the web directory in the nuclear field by using SWING (the total figure achieved : 2,613 titles). We plan that we will positively give more information to the general public interested in the nuclear field and to the experts of the field through this bibliographic information database on KAERI's home page, KAERI's electronic library and other related sites as well as participation at various seminars and meetings related to the nuclear field.

    2013-03-01

    Databases and exchange formats describing biological entities such as chemicals and proteins, along with their relationships, are a critical component of research in life sciences disciplines, including chemical biology wherein small information about small molecule properties converges with cellular and molecular biology. Databases for storing biological entities are growing not only in size, but also in type, with many similarities between them and often subtle differences. The data formats available to describe and exchange these entities are numerous as well. In general, each format is optimized for a particular purpose or database, and hence some understanding of these formats is required when choosing one for research purposes. This paper reviews a selection of different databases and data formats with the goal of summarizing their purposes, features, and limitations. Databases are reviewed under the categories of 1) protein interactions, 2) metabolic pathways, 3) chemical interactions, and 4) drug discovery. Representation formats will be discussed according to those describing chemical structures, and those describing genomic/proteomic entities.

    The bibliography contains citations concerning the development and use of transgenic plants and animals. Transgenic plants and animals are organisms with foreign genes inserted into their cells. Topics include methods of induction of new genes and transgenetic expression in the organism, development of animal models of human diseases, and design of insect tolerant plants. Examples of transgenic organisms include mice, fish, chickens, pigs, rye, maize, tobacco, tomatoes, lettuce, and cotton. This information is of value for the increased production of food from animals by producing animal carcasses with reduced fat content. The information is also valuable for production of herbicide tolerant, virus resistant, and insect resistant crop plants, as well as the rapid production of transgenic plants with flowers and seeds. (Contains 250 citations and includes a subject term index and title list.)

    This bibliography contains citations concerning the development and use of transgenic plants and animals. Topics include methods of induction of new genes and transgenetic expression in the organism, development of animal models of human diseases, and design of insect tolerant plants. Examples of transgenic organisms include mice, fish, chicken, pigs, rye, maize, tobacco, tomatoes, lettuce, and cotton. This information is of value for the increased production of food from animals by producing animal carcasses with reduced fat content. The information is also valuable for production of herbicide tolerant, virus resistant, and insect resistant crop plants, as well as the rapid production of transgenic plants with flowers and seeds. (Contains 383 citations fully indexed and including a title list.)

    An important attribute of the traditional impact factor was the controversial 2-year citation window. So far, several scholars have proposed using different citation time windows for evaluating journals. However, there is no confirmation whether a longer citation time window would be better. How did the journal evaluation effects of 3IF, 4IF, and 6IF comparing with 2IF and 5IF? In order to understand these questions, we made a comparative study of impact factors with different citation time windows with the peer-reviewed scores of ophthalmologic journals indexed by Science Citation Index Expanded (SCIE) database. The peer-reviewed scores of 28 ophthalmologic journals were obtained through a self-designed survey questionnaire. Impact factors with different citation time windows (including 2IF, 3IF, 4IF, 5IF, and 6IF) of 28 ophthalmologic journals were computed and compared in accordance with each impact factor's definition and formula, using the citation analysis function of the Web of Science (WoS) database. An analysis of the correlation between impact factors with different citation time windows and peer-reviewed scores was carried out. Although impact factor values with different citation time windows were different, there was a high level of correlation between them when it came to evaluating journals. In the current study, for ophthalmologic journals' impact factors with different time windows in 2013, 3IF and 4IF seemed the ideal ranges for comparison, when assessed in relation to peer-reviewed scores. In addition, the 3-year and 4-year windows were quite consistent with the cited peak age of documents published by ophthalmologic journals. Our study is based on ophthalmology journals and we only analyze the impact factors with different citation time window in 2013, so it has yet to be ascertained whether other disciplines (especially those with a later cited peak) or other years would follow the same or similar patterns. We designed the survey questionnaire

    Citation metrics and total publications in a field has become the gold standard for rating researchers and viability of a field. Hence, stimulating demand for citation has led to a search for useful strategies to improve performance metric index. Meanwhile, title, abstract and morphologic qualities of the articles attract researchers to scientific publications. Yet, there is relatively little understanding of the citation trend in disability related fields. We aimed to provide an insight into the factors associated with citation increase in this field. Additionally, we tried to know at what page number an article might appear attractive to disability researchers needs. Thus, our focus is placed on the article page count and the number of authors contributing to the fields per article. To this end, we evaluated the quantitative characteristics of top cited articles in the fields with a total citation (≥50) in the Web of Science (WoS) database. Using one-way independent ANOVA, data extracted spanning a period of 1980-2015 were analyzed, while the non-parametric data analysis uses Kruskal-Walis test. Articles with 11 to 20 pages attract more citations followed by those within the range of zero to 10. Articles with upward 21 pages are the least cited. Surprisingly, articles with more than two authors are significantly ( P <0.05) less cited and the citation decreases as the number of authors increased. Collaborative studies enjoy wider utilization and more citation, yet discounted merit of additional pages and limited collaborative research in disability field is revealed in this study.

    Database Tomography (DT) is a textual database analysis system consisting of two major components: (1) algorithms for extracting multi-word phrase frequencies and phrase proximities (physical closeness of the multi-word technical phrases) from any type of large textual database, to augment (2) interpretative capabilities of the expert human analyst. DT was used to derive technical intelligence from a Power Sources database derived from the Science Citation Index. Phrase frequency analysis by the technical domain experts provided the pervasive technical themes of the Power Sources database, and the phrase proximity analysis provided the relationships among the pervasive technical themes. Bibliometric analysis of the Power Sources literature supplemented the DT results with author/journal/institution/country publication and citation data. (author)

    (Written on behalf of the Survey Science Center of the XMM-Newton satellite) The Survey Science Center (SSC) of the XMM-Newton satellite has carried out several large optical campaigns aiming at the spectroscopic identification of samples of about a thousand X-ray sources at various X-ray flux levels and towards different Galactic directions. In addition, the SSC has obtained multi-color wide-field imaging for hundreds of XMM-Newton fields. Building learning samples for the statistical identification of all 2XMM sources was one of the main drivers for undertaking these observing campaigns. However, as demonstrated by the amount of papers published, these collections of data also constitute a very valuable resource which can be used for addressing a wide range of astrophysical issues. We describe the content and architecture of the XID results database recently opened by the SSC and containing a first installment of these data. The interface provides easy selection and browsing through catalogs and access to all optical images and spectral data associated with any given X-ray source as well as all relevant XMM-Newton data. The database was created using the database generator Saada and, together with the XCat-DB already deployed at the Observatoire de Strasbourg, provides another example of the flexibility, ease of use and scalability offered by Saada.

    Full Text Available Citations hold a special place within scientific literature. In fact a scientific paper is deemed credible only when it cites the relevant works and papers on the subject. Citation analysis is a method based on the existing citations within scientific literature. It analyses and evaluates works by counting the number of citations used in different texts such as journals, dissertations and such. The emergence of citation indices has contributed to the remarkable growth and development of citation analysis, making it a significant research area over the past couple of decades. The present paper deals with the importance of citations and citation theories. Definitions and historical background on citation analysis as well as its various field applications are discussed.

    Full Text Available 本研究提出一個測量期刊引用影響的整合式概念模型,並應用結構方程模式方法在圖書資訊學相關領域的50種期刊資訊進行以「期刊屬性」、「期刊易取性」及「期刊多樣性」等三項為「期刊引用」的前置因素理論模型的實證。整體模型的可解釋變異量為39.4%,其中測量模型的結果:以文獻篇數測量「期刊屬性」,以文件獲取性測量「期刊易取性」,及主題多樣化來測量「期刊多樣性」具顯著效果;而影響係數、立即指數及全部引用數來測量「期刊引用」,則均具顯著效果。結構模型的結果:「期刊引用」受到「期刊多樣性」的影響,但「期刊屬性」與「期刊易取性」則不具顯著性影響。The study proposes an integrated conceptual model to assess the journal citation impact. The antecedent factors include journal attributes, journal accessibility, and journal diversity. The structural equation modeling (SEM with partial least square (PLS is applied to conduct the empirical study within the fifty journals in the field of library and information science. The result shows that the antecedent factors account for 39.4% of the variance in journal citation. The result of measurement model shows that the number of articles is a good indicator for journal attributes; document availability is a good indicator for journal accessibility; and subject variety is a good indicator for journal diversity. As for the journal citation, three indicators include impact factor, immediacy index, and total citations are all good indicators. Moreover, the result of structural model shows that journal citation is significantly influenced by journal diversity, while there is no significant effect of journal attributes and journal accessibility.

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition we study the distributions of the different indices which also behave similarly.

  15. Successful ageing: A study of the literature using citation network analysis.

    Ageing is accompanied by an increased risk of disease and a loss of functioning on several bodily and mental domains and some argue that maintaining health and functioning is essential for a successful old age. Paradoxically, studies have shown that overall wellbeing follows a curvilinear pattern with the lowest point at middle age but increases thereafter up to very old age. To shed further light on this paradox, we reviewed the existing literature on how scholars define successful ageing and how they weigh the contribution of health and functioning to define success. We performed a novel, hypothesis-free and quantitative analysis of citation networks exploring the literature on successful ageing that exists in the Web of Science Core Collection Database using the CitNetExplorer software. Outcomes were visualized using timeline-based citation patterns. The clusters and sub-clusters of citation networks identified were starting points for in-depth qualitative analysis. Within the literature from 1902 through 2015, two distinct citation networks were identified. The first cluster had 1146 publications and 3946 citation links. It focused on successful ageing from the perspective of older persons themselves. Analysis of the various sub-clusters emphasized the importance of coping strategies, psycho-social engagement, and cultural differences. The second cluster had 609 publications and 1682 citation links and viewed successful ageing based on the objective measurements as determined by researchers. Subsequent sub-clustering analysis pointed to different domains of functioning and various ways of assessment. In the current literature two mutually exclusive concepts of successful ageing are circulating that depend on whether the individual himself or an outsider judges the situation. These different points of view help to explain the disability paradox, as successful ageing lies in the eyes of the beholder. Copyright © 2016 The Authors. Published by Elsevier Ireland

    To meet the future challenges of infectious diseases and limit the spread of multidrug resistant microorganisms, a better understanding of published studies in the field of infectious diseases is needed. The objective of this study was to analyze the quantity and quality of research activity in the field of infectious diseases in Arab countries and compare it with that in non-Arab countries. Documents published in Arab countries within the research category of "infectious diseases" were extracted and analyzed using the Web of Science database. The data analyzed represent research productivity during the time interval between 1900 - 2012. Worldwide, the total number of documents published in the field of infectious diseases up to 2012 was 227,188. A total of 2,408 documents in the field of infectious diseases were published in Arab countries, which represents 1.06% of worldwide research output. Research output from Arab countries in the field of infectious diseases was low for decades. However, approximately a five-fold increase was observed in the past decade. Arab countries ranked 56(th) to 218(th) on the standard competition ranking (SCR) in worldwide publications in the field of infectious diseases. Egypt, with a total publication of 464 (19.27%) documents ranked first among Arab countries, while Kuwait University was the most productive institution with a total of 158 (6.56%) documents. Average citation per document published in Arab countries was 13.25 and the h-index was 64. Tuberculosis (230; 9.55%), malaria (223; 9.26%), and hepatitis (189; 7.8%) were the top three infectious diseases studied as according to the retrieved documents. The present data reveals that some Arab countries contribute significantly to the field of infectious diseases. However, Arab countries need to work harder to bridge the gap in this field. Compared with non-Arab countries in the Middle East, research output from Arab countries was high, but more efforts are needed to enhance the

    In this study the amount of informal citations (i.e. those mentioning only author names or their initials instead of the complete references) in comparison to the formal (full reference based) citations is analyzed using some pioneers of chemistry and physics as examples. The data reveal that the formal citations often measure only a small fraction of the overall impact of seminal publications. Furthermore, informal citations are mainly given instead of (and not in addition to) formal citatio...

    2016-01-01

    A paradigm change in scholarly communication is underway. Supporting Open Science, an effort to make scientific research data accessible to all interested parties by openly publishing research and encouraging others to do the same thereby making it easier to communicate scientific knowledge, is a part of the change that has become increasingly important for (digital) libraries. Digital libraries are able to play a significant role in enabling Open Science by facilitating data sharing, discovery and re-use. Because data citation is often mentioned as one incentive for data sharing, enabling data citation is a crucial feature of research data services. In this article we present a case study of data citation services for the High-Energy Physics (HEP) community using digital library technology. Our example shows how the concept of data citation is implemented for the complete research workflow, covering data production, publishing, citation and tracking of data reuse. We also describe challenges faced and distil...

  20. Alphabetical co-authorship in the social sciences and humanities: evidence from a comprehensive local database

    2016-07-01

    We present an analysis of alphabetical co-authorship in the social sciences and humanities (SSH), based on data from the VABB-SHW, a comprehensive database of SSH research output in Flanders (2000-2013). Using an unbiased estimator of the share of intentional alphabetical co-authorship (IAC), we find that alphabetical co-authorship is more engrained in SSH than in science as a whole. Within the SSH, large differences exist between disciplines. The highest proportions of IAC are found for Literature, Economics & business, and History. Furthermore, alphabetical co-authorship varies with publication type: it occurs most often in books, is less common in articles in journals or in books, and is rare in proceedings papers. The use of alphabetical co-authorship appears to be slowly declining. (Author)
