  2. Investigations into Library Web-Scale Discovery Services

    Directory of Open Access Journals (Sweden)

    Jason Vaughan

    2008-03-01

    Full Text Available Web-scale discovery services for libraries provide deep discovery to a library’s local and licensed content, and represent an evolution, perhaps a revolution, for end user information discovery as pertains to library collections.  This article frames the topic of web-scale discovery, and begins by illuminating web-scale discovery from an academic library’s perspective – that is, the internal perspective seeking widespread staff participation in the discovery conversation.  This included the creation of a discovery task force, a group which educated library staff, conducted internal staff surveys, and gathered observations from early adopters.  The article next addresses the substantial research conducted with library vendors which have developed these services.  Such work included drafting of multiple comprehensive question lists distributed to the vendors, onsite vendor visits, and continual tracking of service enhancements.  Together, feedback gained from library staff, insights arrived at by the Discovery Task Force, and information gathered from vendors collectively informed the recommendation of a service for the UNLV Libraries.

  12. A web-based library consult service for evidence-based medicine: Technical development

    Directory of Open Access Journals (Sweden)

    Schwartz Alan

    2006-03-01

    Full Text Available Abstract Background Incorporating evidence based medicine (EBM into clinical practice requires clinicians to learn to efficiently gain access to clinical evidence and effectively appraise its validity. Even using current electronic systems, selecting literature-based data to solve a single patient-related problem can require more time than practicing physicians or residents can spare. Clinical librarians, as informationists, are uniquely suited to assist physicians in this endeavor. Results To improve support for evidence-based practice, we have developed a web-based EBM library consult service application (LCS. Librarians use the LCS system to provide full text evidence-based literature with critical appraisal in response to a clinical question asked by a remote physician. LCS uses an entirely Free/Open Source Software platform and will be released under a Free Software license. In the first year of the LCS project, the software was successfully developed and a reference implementation put into active use. Two years of evaluation of the clinical, educational, and attitudinal impact on physician-users and librarian staff are underway, and expected to lead to refinement and wide dissemination of the system. Conclusion A web-based EBM library consult model may provide a useful way for informationists to assist clinicians, and is feasible to implement.

  15. Web pages of Slovenian public libraries

    Directory of Open Access Journals (Sweden)

    Silva Novljan

    2002-01-01

    Full Text Available Libraries should offer their patrons web sites which establish the unmistakeable concept (public of library, the concept that cannot be mistaken for other information brokers and services available on the Internet, but inside this framework of the concept of library, would show a diversity which directs patrons to other (public libraries. This can be achieved by reliability, quality of information and services, and safety of usage.Achieving this, patrons regard library web sites as important reference sources deserving continuous usage for obtaining relevant information. Libraries excuse investment in the development and sustainance of their web sites by the number of visits and by patron satisfaction. The presented research, made on a sample of Slovene public libraries’web sites, determines how the libraries establish their purpose and role, as well as the given professional recommendations in web site design.The results uncover the striving of libraries for the modernisation of their functions,major attention is directed to the presentation of classic libraries and their activities,lesser to the expansion of available contents and electronic sources. Pointing to their diversity is significant since it is not a result of patrons’ needs, but more the consequence of improvisation, too little attention to selection, availability, organisation and formation of different kind of information and services on the web sites. Based on the analysis of a common concept of the public library web site, certain activities for improving the existing state of affairs are presented in the paper.

  17. Web-scale discovery in an academic health sciences library: development and implementation of the EBSCO Discovery Service.

    Science.gov (United States)

    Thompson, Jolinda L; Obrig, Kathe S; Abate, Laura E

    2013-01-01

    Funds made available at the close of the 2010-11 fiscal year allowed purchase of the EBSCO Discovery Service (EDS) for a year-long trial. The appeal of this web-scale discovery product that offers a Google-like interface to library resources was counter-balanced by concerns about quality of search results in an academic health science setting and the challenge of configuring an interface that serves the needs of a diverse group of library users. After initial configuration, usability testing with library users revealed the need for further work before general release. Of greatest concern were continuing issues with the relevance of items retrieved, appropriateness of system-supplied facet terms, and user difficulties with navigating the interface. EBSCO has worked with the library to better understand and identify problems and solutions. External roll-out to users occurred in June 2012.

    Full Text Available Objective – To determine the prevalence and use of web 2.0 applications in library websites and to determine whether or not their presence enhances the quality of the sites.Design – Content analysis.Setting – Public and academic libraries in North America, Europe, and Asia.Subjects – A total of 120 academic and public library websites in English.Methods – This study identified and selected library websites from academic and public libraries using a combination of directories, ratings reports, and ranking lists from three geographic regions. Over a four-month period in 2009, three coders conducted a three-step content analysis of the selected library websites. This analysis was conducted after having established inter-coder reliability using Cohen’s Kappa and analytic procedure familiarity, using a randomly selected pilot set of 30 library websites. The remaining 90 websites were evenly distributed among the three coders for analysis. They determined whether web 2.0 applications were present, examined how those applications were used, and gave an overall appraisal of website quality. Coders inspected library website links, conducted site searches, used search engines, and searched within major social networking sites to determine the presence of web 2.0 applications. A quality framework classification scheme was used during coding to identify how the web 2.0 applications were being used within library websites. This framework was established around four dimensions of library services: information acquisition (blogs and wikis, information dissemination (Rich Site Summary, or “RSS”, information organization (social tagging, and information sharing (social networking and instant messaging. A five-point Likert scale was also used in concert with a website quality evaluation framework to assess the quality of the library websites.

    Vanquelef, Enguerran; Simon, Sabrina; Marquant, Gaelle; Garcia, Elodie; Klimerak, Geoffroy; Delepine, Jean Charles; Cieplak, Piotr; Dupradeau, François-Yves

    2011-01-01

    R.E.D. Server is a unique, open web service, designed to derive non-polarizable RESP and ESP charges and to build force field libraries for new molecules/molecular fragments. It provides to computational biologists the means to derive rigorously molecular electrostatic potential-based charges embedded in force field libraries that are ready to be used in force field development, charge validation and molecular dynamics simulations. R.E.D. Server interfaces quantum mechanics programs, the RESP program and the latest version of the R.E.D. tools. A two step approach has been developed. The first one consists of preparing P2N file(s) to rigorously define key elements such as atom names, topology and chemical equivalencing needed when building a force field library. Then, P2N files are used to derive RESP or ESP charges embedded in force field libraries in the Tripos mol2 format. In complex cases an entire set of force field libraries or force field topology database is generated. Other features developed in R.E.D. Server include help services, a demonstration, tutorials, frequently asked questions, Jmol-based tools useful to construct PDB input files and parse R.E.D. Server outputs as well as a graphical queuing system allowing any user to check the status of R.E.D. Server jobs. PMID:21609950

  17. Chapter 59: Web Services

    Science.gov (United States)

    Graham, M. J.

    Web services are a cornerstone of the distributed computing infrastructure that the VO is built upon yet to the newcomer, they can appear to be a black art. This perception is not helped by the miasma of technobabble that pervades the subject and the seemingly impenetrable high priesthood of actual users. In truth, however, there is nothing conceptually difficult about web services (unsurprisingly any complexities will lie in the implementation details) nor indeed anything particularly new. A web service is a piece of software available over a network with a formal description of how it is called and what it returns that a computer can understand. Note that entities such as web servers, ftp servers and database servers do not generally qualify as they lack the standardized description of their inputs and outputs. There are prior technologies, such as RMI, CORBA, and DCOM, that have employed a similar approach but the success of web services lies predominantly in its use of standardized XML to provide a language-neutral way for representing data. In fact, the standardization goes further as web services are traditionally (or as traditionally as five years will allow) tied to a specific set of technologies (WSDL and SOAP conveyed using HTTP with an XML serialization). Alternative implementations are becoming increasingly common and we will cover some of these here. One important thing to remember in all of this, though, is that web services are meant for use by computers and not humans (unlike web pages) and this is why so much of it seems incomprehensible gobbledegook. In this chapter, we will start with an overview of the web services current in the VO and present a short guide on how to use and deploy a web service. We will then review the different approaches to web services, particularly REST and SOAP, and alternatives to XML as a data format. We will consider how web services can be formally described and discuss how advanced features such as security, state

    2015-01-01

    Full Text Available The increasing availability and popularity of computer systems has resulted in a demand for new, language- and platform-independent ways of data exchange. That demand has in turn led to a significant growth in the importance of systems based on Web services. Alongside the growing number of systems accessible via Web services came the need for specialized data repositories that could offer effective means of searching of available services. The development of mobile systems and wireless data transmission technologies has allowed the use of distributed devices and computer systems on a greater scale. The accelerating growth of distributed systems might be a good reason to consider the development of distributed Web service repositories with built-in mechanisms for data migration and synchronization.

    Yarfitz, S; Ketchell, D S

    2000-01-01

    Support for molecular biology researchers has been limited to traditional library resources and services in most academic health sciences libraries. The University of Washington Health Sciences Libraries have been providing specialized services to this user community since 1995. The library recruited a Ph.D. biologist to assess the molecular biological information needs of researchers and design strategies to enhance library resources and services. A survey of laboratory research groups identified areas of greatest need and led to the development of a three-pronged program: consultation, education, and resource development. Outcomes of this program include bioinformatics consultation services, library-based and graduate level courses, networking of sequence analysis tools, and a biological research Web site. Bioinformatics clients are drawn from diverse departments and include clinical researchers in need of tools that are not readily available outside of basic sciences laboratories. Evaluation and usage statistics indicate that researchers, regardless of departmental affiliation or position, require support to access molecular biology and genetics resources. Centralizing such services in the library is a natural synergy of interests and enhances the provision of traditional library resources. Successful implementation of a library-based bioinformatics program requires both subject-specific and library and information technology expertise.

    1983-01-01

    Dental school libraries offer resources of value to dental practitioners, but do not always consider practitioners to be primary clientele. A survey was conducted among the sixty U.S. dental school libraries to examine policies and attitudes toward service to practitioners. Although library use by dentists is estimated to be low, most libraries are willing to serve them as long as it does not reduce the libraries' ability to assist students and faculty. Of the respondents, 57% replied that they do not use promotional methods to inform dentists of available services. Greater involvement in marketing activities may benefit both libraries and dentists.

    Full Text Available With an abundance of library resources being served on the web, researchers are finding that disabled people oftentimes do not have the same level of access to materials as their nondisabled peers. This paper discusses web accessibility in the context of United States’ federal laws most referenced in web accessibility lawsuits. Additionally, it reveals which states have statutes that mirror federal web accessibility guidelines and to what extent. Interestingly, fewer than half of the states have adopted statutes addressing web accessibility, and fewer than half of these reference Section 508 of the Rehabilitation Act or Web Content Accessibility Guidelines (WCAG 1.0. Regardless of sparse legislation surrounding web accessibility, librarians should consult the appropriate web accessibility resources to ensure that their specialized content reaches all.

    The EMBRACE (European Model for Bioinformatics Research and Community Education) web service collection is the culmination of a 5-year project that set out to investigate issues involved in developing and deploying web services for use in the life sciences. The project concluded that in order for web services to achieve widespread adoption, standards must be defined for the choice of web service technology, for semantically annotating both service function and the data exchanged, and a mechanism for discovering services must be provided. Building on this, the project developed: EDAM, an ontology for describing life science web services; BioXSD, a schema for exchanging data between services; and a centralized registry (http://www.embraceregistry.net) that collects together around 1000 services developed by the consortium partners. This article presents the current status of the collection and its associated recommendations and standards definitions.

    2008-01-01

    A syntactic and structural matching mechanism for service discovery was put forward, which tries to exploit the underlying semantics of web services to enhance the traditional syntactic service discovery. We commit WSDL (Web Service Description Language) as service description language. The syntactic matching mechanism is based on the textual similarity among WSDL documents using VSM (Vector Space Model). The structural information is extracted from WSDL document tree or the invocation sequence of a series of services which can be viewed as the problem of graph isomorphism. Then we combine the syntactic and structural similarity linearly to calculate the service similarity. Finally we provide a novel web services discovery framework named SG* to find the exact services meeting the users' goals based on service similarity.

    Full Text Available Information and communication technologies are designed to support and anticipate the continuing changes of the information society, while outlining new economic, social and cultural dimensions. We see the growth of new business models whose aim is to remove traditional barriers and improve the value of goods and services. Information is a strategic resource and its manipulation raises new problems for all entities involved in the process. Information and communication technologies should be a stable support in managing the flow of data and support the integrity, confidentiality and availability. Concepts such as eBusiness, eCommerce, Software as a Service, Cloud Computing and Social Media are based on web technologies consisting of complex languages, protocols and standards, built around client-server architecture. One of the most used technologies in mobile applications are the Web Services defined as an application model supported by any operating system able to provide certain functionalities using Internet technologies to promote interoperability between various appli-cations and platforms. Web services use HTTP, XML, SSL, SMTP and SOAP, because their stability has proven over the years. Their functionalities are highly variable, with Web services applications exchange type, weather, arithmetic or authentication services. In this article we will talk about SOAP and REST architectures for web services in mobile applications and we will also provide some practical examples based on Android platform.

    The OGC Web Processing Service (WPS) provides a standard for implementing geospatial processes in service-oriented networks. In its current version 1.0.0 it allocates the operations GetCapabilities, DescribeProcess and Execute, which can be used to offer custom processes based on single or multiple sub-processes. A large range of ready to use fine granular, fundamental geospatial processes have been developed by the GIS-community in the past. However, modern use cases or whole workflow processes demand specifications of lifecycle management and service orchestration. Orchestrating smaller sub-processes is a task towards interoperability; a comprehensive documentation by using appropriate metadata is also required. Though different approaches were tested in the past, developing complex WPS applications still requires programming skills, knowledge about software libraries in use and a lot of effort for integration. Our toolset RichWPS aims at providing a better overall experience by setting up two major components. The RichWPS ModelBuilder enables the graphics-aided design of workflow processes based on existing local and distributed processes and geospatial services. Once tested by the RichWPS Server, a composition can be deployed for production use on the RichWPS Server. The ModelBuilder obtains necessary processes and services from a directory service, the RichWPS semantic proxy. It manages the lifecycle and is able to visualize results and debugging-information. One aim will be to generate reproducible results; the workflow should be documented by metadata that can be integrated in Spatial Data Infrastructures. The RichWPS Server provides a set of interfaces to the ModelBuilder for, among others, testing composed workflow sequences, estimating their performance and to publish them as common processes. Therefore the server is oriented towards the upcoming WPS 2.0 standard and its ability to transactionally deploy and undeploy processes making use of a WPS

We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some

    2011-12-01

    With the development of Web services technology, the number of service increases rapidly, and it becomes a challenge task that how to efficiently discovery the services that exactly match the user's requirements from the large scale of services library. Many semantic Web services discovery technologies proposed by the recent literatures only focus on the keyword-based or primary semantic based service's matching. This paper studies the rules and rule reasoning based service matching algorithm in the background of large scale services library. Firstly, the formal descriptions of semantic web services and service matching is presented. The services' matching are divided into four levels: Exact, Plugin, Subsume and Fail and their formal descriptions are also presented. Then, the service matching is regarded as rule-based reasoning issues. A set of match rules are firstly given and the related services set is retrieved from services ontology base through rule-based reasoning, and their matching levels are determined by distinguishing the relationships between service's I/O and user's request I/O. Finally, the experiment based on two services sets show that the proposed services matching strategy can easily implement the smart service discovery and obtains the high service discovery efficiency in comparison with the traditional global traversal strategy.

    2015-07-01

    Full Text Available A distributed application may be composed of global services provided by different organizations and having different properties. To select a service from many similar services, it is important to distinguish between them. Quality of services (QoS has been used as a distinguishing factor between similar services and plays an important role in service discovery, selection, and composition. Moreover, QoS is an important contributing factor to the evolution of distributed paradigms, such as service-oriented computing and cloud computing. There are many research works that assess services and justify the QoS at the finding, composition, or binding stages of services. However, there is a need to justify the QoS once new services are registered and before any requestors use them; this is called bootstrapping QoS. Bootstrapping QoS is the process of evaluating the QoS of the newly registered services at the time of publishing the services. Thus, this paper proposes a QoS bootstrapping solution for Web Services and builds a QoS bootstrapping framework. In addition, Service Oriented Architecture (SOA is extended and a prototype is built to support QoS bootstrapping. Experiments are conducted and a case study is presented to test the proposed QoS bootstrapping solution.

    Full Text Available Public libraries are used by a wide range of users. Therefore they should offer as many different services as possible. The proper introduction of library services to the users can be monitored by measuring their expectations. The article represents the services, which public libraries should offer to their users, definition of the expectation and which factors influence forming the expectations. 60 users were interviewed in two public libraries. The purpose of research was to find out how expectation differs from public library service offer. The results show that most users expect traditional library services such as free access to books, loaning books, giving information over the phone, reading rooms and inter-library loan; furthermore, most users expect library consultancy and advisory services, access to the Internet, public library website, on-line library catalog and services for the youngest members of the library. Fewer users expect guided tour of the library and information on cultural events in the city. Very few users expect modern services, such as provision of electronic publications, courses or lectures for using the Internet and other electronic sources, special courses, such as how to write a scientific research, and services for leisure and recreation, such as organized trips, and fun activities, such as arranging flowers, painting, sawing, etc.

    2010-01-01

    Mobile data services in combination with profluent web services are seemingly the path breaking domain in current information research. Effectively, these mobile web services will pave the way for exciting performance and security challenges, the core need-to-be-addressed issues. On security front, though a lot of standardized security specifications and implementations exist for web services in the wired networks, not much has been analysed and standardized in the wireless environments. This paper addresses some of the critical challenges in providing security to the mobile web service domain. We first explore mobile web services and their key security issues, with special focus on provisioning based on a mobile web service provider realized by us. Later we discuss state-of-the-art security awareness in the wired and wireless web services, and finally address the realization of security for the mobile web service provisioning with performance analysis results.

These giants already offer their APIs to other programmers and allow for add-on services and mash-ups to develop from them--but until recently, the capability for most enterprises to do the same was limited by a myriad of competing standards and a lack of easy-to-use tools to accomplish the task. Ruby on Rails levels the playing field for companies by simplifying the process

    Web services are becoming an important paradigm for web-based computing. However the mainstream web service description language such as WSDL (Web Service Description Language) is lack of formal basis. In order to verify the behavioral properties of web services, we adopt the π-calculus as a precise language because it provides many useful facilities such as behavioral equivalence, mobility that are lack in other formal language. The basic elements of WSDL are translated into the terms in the π-calculus. By means of the MWB (Mobility Workbench), a concurrency tool, the behavioral property of web services denoted by processes is verified.

    To allow scientists further capabilities in the area of data mining and web services, the Goddard Earth Sciences Data and Information Services Center (GES DISC) and researchers at the University of Alabama in Huntsville (UAH) have developed a system to mine data at the source without the need of network transfers. The system has been constructed by linking together several pre-existing technologies: the Simple Scalable Script-based Science Processor for Measurements (S4PM), a processing engine at he GES DISC; the Algorithm Development and Mining (ADaM) system, a data mining toolkit from UAH that can be configured in a variety of ways to create customized mining processes; ActiveBPEL, a workflow execution engine based on BPEL (Business Process Execution Language); XBaya, a graphical workflow composer; and the EOS Clearinghouse (ECHO). XBaya is used to construct an analysis workflow at UAH using ADam components, which are also installed remotely at the GES DISC, wrapped as Web Services. The S4PM processing engine searches ECHO for data using space-time criteria, staging them to cache, allowing the ActiveBPEL engine to remotely orchestras the processing workflow within S4PM. As mining is completed, the output is placed in an FTP holding area for the end user. The goals are to give users control over the data they want to process, while mining data at the data source using the server's resources rather than transferring the full volume over the internet. These diverse technologies have been infused into a functioning, distributed system with only minor changes to the underlying technologies. The key to the infusion is the loosely coupled, Web-Services based architecture: All of the participating components are accessible (one way or another) through (Simple Object Access Protocol) SOAP-based Web Services.

    Full Text Available State-of-art systems provide comprehensive solutions almost to all users from the data pre-processing through data processing to their final presentation. Consequently, these solutions are very expensive and unavailable for some potential end users. Thus, several questions come up. Do we really need all these functions and, if not why do we have to pay for them? Is it possible to develop such a system with all these functions but without the need of end users to pay extra money for that? In the following text the authors will try to answer the above questions. Web services are a hit of the day. On many experts opinions web services represent a standard for a new information system generation. A prove of this statement could be the fact that every new software product support this form of the internet use. Also in the geoinformatics, this facility is successfully used for a long time (e.g. WMS, WFS. But as all, even web services are further developed and also native protocols, based on the XML format, are subsequently replaced by general protocols (e.g. SOAP.These protocols also use XML, but they enable the development of distributed systems with paralleled features using the Internet as a communication middleware. Thus, it is possible to develop wide information systems with a high level of modularity and integration with existing systems. The paper describes the architecture for the development of open and modular systems.

    Full Text Available This article posits a definition and theory for "Library 2.0". It suggests that recent thinking describing the changing Web as "Web 2.0" will have substantial implications for libraries, and recognizes that while these implications keep very close to the history and mission of libraries, they still necessitate a new paradigm for librarianship. The paper applies the theory and definition to the practice of librarianship, specifically addressing how Web 2.0 technologies such as synchronous messaging and streaming media, blogs, wikis, social networks, tagging, RSS feeds, and mashups might intimate changes in how libraries provide access to their collections and user support for that access.

    Business processes involve dynamic compositions of interleaved tasks. Therefore, ensuring reliable transactional processing of Web services is crucial for the success of Web service-based B2B and B2C applications. But the inherent autonomy and heterogeneity of Web services render the applicability...... of conventional ACID transaction models for Web services far from being straightforward. Current Web service transaction models relax the isolation property and rely on compensation mechanisms to ensure atomicity of business transactions in the presence of service failures. However, ensuring consistency...... in the open and dynamic environment of Web services, where interleaving business transactions enter and exit the system independently, remains an open issue. In this paper, we address this problem and propose an architecture that supports concurrency control on the Web services level. An extension...

Currently it is spoken more and more about a new type of service offered by them, Library 2.0, which brings in foreground the user who becomes a modeler of the library services and resources. The information structures customer is not satisfied anymore by the unidirectional access to the resources, he wanted to be involved in the evaluation of them, making comments and sharing his ideas with another user. In this sense the library managers are looking for more efficient means to deliver services so that to obtain a proper feedback which enable them to take the best measures to make profitable them.

    Peng, Hui; Niu, Wenjia; Huang, Ronghuai

    Semantic web service discovery aims at returning the most matching advertised services to the service requester by comparing the semantic of the request service with an advertised service. The semantic of a web service are described in terms of inputs, outputs, preconditions and results in Ontology Web Language for Service (OWL-S) which formalized by W3C. In this paper we proposed an algorithm to calculate the semantic similarity of two services by weighted averaging their inputs and outputs similarities. Case study and applications show the effectiveness of our algorithm in service match.

  17. Web-based Altimeter Service

    Science.gov (United States)

    Callahan, P. S.; Wilson, B. D.; Xing, Z.; Raskin, R. G.

    2010-12-01

    We have developed a web-based system to allow updating and subsetting of TOPEX data. The Altimeter Service will be operated by PODAAC along with their other provision of oceanographic data. The Service could be easily expanded to other mission data. An Altimeter Service is crucial to the improvement and expanded use of altimeter data. A service is necessary for altimetry because the result of most interest - sea surface height anomaly (SSHA) - is composed of several components that are updated individually and irregularly by specialized experts. This makes it difficult for projects to provide the most up-to-date products. Some components are the subject of ongoing research, so the ability for investigators to make products for comparison or sharing is important. The service will allow investigators/producers to get their component models or processing into widespread use much more quickly. For coastal altimetry, the ability to subset the data to the area of interest and insert specialized models (e.g., tides) or data processing results is crucial. A key part of the Altimeter Service is having data producers provide updated or local models and data. In order for this to succeed, producers need to register their products with the Altimeter Service and to provide the product in a form consistent with the service update methods. We will describe the capabilities of the web service and the methods for providing new components. Currently the Service is providing TOPEX GDRs with Retracking (RGDRs) in netCDF format that has been coordinated with Jason data.

  5. Going, going, still there: using the WebCite service to permanently archive cited web pages.

    Science.gov (United States)

    Eysenbach, Gunther; Trudel, Mathieu

    2005-12-30

    Scholars are increasingly citing electronic "web references" which are not preserved in libraries or full text archives. WebCite is a new standard for citing web references. To "webcite" a document involves archiving the cited Web page through www.webcitation.org and citing the WebCite permalink instead of (or in addition to) the unstable live Web page. This journal has amended its "instructions for authors" accordingly, asking authors to archive cited Web pages before submitting a manuscript. Almost 200 other journals are already using the system. We discuss the rationale for WebCite, its technology, and how scholars, editors, and publishers can benefit from the service. Citing scholars initiate an archiving process of all cited Web references, ideally before they submit a manuscript. Authors of online documents and websites which are expected to be cited by others can ensure that their work is permanently available by creating an archived copy using WebCite and providing the citation information including the WebCite link on their Web document(s). Editors should ask their authors to cache all cited Web addresses (Uniform Resource Locators, or URLs) "prospectively" before submitting their manuscripts to their journal. Editors and publishers should also instruct their copyeditors to cache cited Web material if the author has not done so already. Finally, WebCite can process publisher submitted "citing articles" (submitted for example as eXtensible Markup Language [XML] documents) to automatically archive all cited Web pages shortly before or on publication. Finally, WebCite can act as a focussed crawler, caching retrospectively references of already published articles. Copyright issues are addressed by honouring respective Internet standards (robot exclusion files, no-cache and no-archive tags). Long-term preservation is ensured by agreements with libraries and digital preservation organizations. The resulting WebCite Index may also have applications for research

  6. Ontology Based Qos Driven Web Service Discovery

    2011-07-01

    Full Text Available In today's scenario web services have become a grand vision to implement the business process functionalities. With increase in number of similar web services, one of the essential challenges is to discover relevant web service with regard to user specification. Relevancy of web service discovery can be improved by augmenting semantics through expressive formats like OWL. QoS based service selection will play a significant role in meeting the non-functional user requirements. Hence QoS and semantics has been used as finer search constraints to discover the most relevant service. In this paper, we describe a QoS framework for ontology based web service discovery. The QoS factors taken into consideration are execution time, response time, throughput, scalability, reputation, accessibility and availability. The behavior of each web service at various instances is observed over a period of time and their QoS based performance is analyzed.

The experimental results show that the proposed algorithm has better matching effect when fuzzy semantic concepts exist .

    Mallayya, Deivamani; Ramachandran, Baskaran; Viswanathan, Suganya

    2015-01-01

    Web service has become the technology of choice for service oriented computing to meet the interoperability demands in web applications. In the Internet era, the exponential addition of web services nominates the "quality of service" as essential parameter in discriminating the web services. In this paper, a user preference based web service ranking (UPWSR) algorithm is proposed to rank web services based on user preferences and QoS aspect of the web service. When the user's request cannot be fulfilled by a single atomic service, several existing services should be composed and delivered as a composition. The proposed framework allows the user to specify the local and global constraints for composite web services which improves flexibility. UPWSR algorithm identifies best fit services for each task in the user request and, by choosing the number of candidate services for each task, reduces the time to generate the composition plans. To tackle the problem of web service composition, QoS aware automatic web service composition (QAWSC) algorithm proposed in this paper is based on the QoS aspects of the web services and user preferences. The proposed framework allows user to provide feedback about the composite service which improves the reputation of the services.

    W3C standardized Web Services are becoming an increasingly popular middleware technology used to facilitate the open exchange of chemical data. While several projects in existence use Web Services to wrap existing commercial and open-source tools that mine chemical structure data, no Web Service infrastructure has yet been developed to compute thermochemical properties of substances. This work presents an infrastructure of Web Services for thermochemical data retrieval. Several examples are presented to demonstrate how our Web Services can be called from Java, through JavaScript using an AJAX methodology, and within commonly used commercial applications such as Microsoft Excel and MATLAB for use in computational work. We illustrate how a JANAF table, widely used by chemists and engineers, can be quickly reproduced through our Web Service infrastructure.

    The transition of the World Wide Web from a paradigm of static Web pages to one of dynamic Web services provides new and exciting opportunities for bioinformatics with respect to data dissemination, transformation, and integration. However, the rapid growth of bioinformatics services, coupled with non-standardized interfaces, diminish the potential that these Web services offer. To face this challenge, we examine the notion of a Web service class that defines the functionality provided by a collection of interfaces. These descriptions are an integral part of a larger framework that can be used to discover, classify, and wrapWeb services automatically. We discuss how this framework can be used in the context of the proliferation of sites offering BLAST sequence alignment services for specialized data sets.

    For advanced web search engines to be able not only to search for semantically related information dispersed over different web pages, but also for semantic services providing certain functionalities, discovering semantic services is the key issue. Addressing four problems of current solution, this book presents the following contributions. A novel service model independent of semantic service description models is proposed, which clearly defines all elements necessary for service discovery and selection. It takes service selection as its gist and improves efficiency. Corresponding selection algorithms and their implementation as components of the extended Semantically Enabled Service-oriented Architecture in the Web Service Modeling Environment are detailed. Many applications of semantic web services, e.g. discovery, composition and mediation, can benefit from a general approach for building application ontologies. With application ontologies thus built, services are discovered in the same way as with single...

    Use of web services also on mobile devices becomes increasingly relevant. However, realizing such mobile web services based on the standard protocol stack is often inappropriate for resource-restricted mobile devices in dynamic networks. On the other hand, using specialized alternative protocols restricts compatibility with traditional service applications. Thus, existing approaches often do not allow to integrate heterogeneous service instances dynamically, as it is, e.g., required for executing mobile service-based business processes.

    2016-10-01

    The study investigated veterinary medicine librarians' experience with and perceptions of research data services. Many academic libraries have begun to offer research data services in response to researchers' increased need for data management support. To date, such services have typically been generic, rather than discipline-specific, to appeal to a wide variety of researchers. An online survey was deployed to identify trends regarding research data services in veterinary medicine libraries. Participants were identified from a list of contacts from the MLA Veterinary Medical Libraries Section. Although many respondents indicated that they have a professional interest in research data services, the majority of veterinary medicine librarians only rarely or occasionally provide data management support as part of their regular job responsibilities. There was little consensus as to whether research data services should be core to a library's mission despite their perceived importance to the advancement of veterinary research. Furthermore, most respondents stated that research data services are just as or somewhat less important than the other services that they provide and feel only slightly or somewhat prepared to offer such services. Lacking a standard definition of "research data" and a common understanding of precisely what research data services encompass, it is difficult for veterinary medicine librarians and libraries to define and understand their roles in research data services. Nonetheless, they appear to have an interest in learning more about and providing research data services.

Our probabilistic topic model is a latent variable model that exploits local correlation labels. Indeed, exploiting label correlations is a challenging and crucial problem especially in multi-label learning context. Moreover, several existing systems can recommend tags for web services based on existing manual tags. In most cases, the manual tags have better quality. We also develop three strategies to automatically recommend the best tags for web services. We also propose, in this paper, WS-Portal; An Enriched Web Services Search Engine which contains 7063 providers, 115 sub-classes of category and 22236 web services crawled from the Internet. In WS-Portal, severals technologies are employed to improve the effectiveness of web service discovery (i.e. web services clustering, tags recommendation, services rating and monitoring. Our experiments are performed out based on real-world web services. The comparisons of Precision@n, Normalised Discounted Cumulative Gain (NDCGn values for our approach indicate that the method presented in this paper outperforms the method based on the CorrLDA in terms of ranking and quality of generated tags.

    2005-03-01

    Full Text Available Abstract Background The population genetic pattern known as "isolation by distance" results from spatially limited gene flow and is a commonly observed phenomenon in natural populations. However, few software programs exist for estimating the degree of isolation by distance among populations, and they tend not to be user-friendly. Results We have created Isolation by Distance Web Service (IBDWS a user-friendly web interface for determining patterns of isolation by distance. Using this site, population geneticists can perform a variety of powerful statistical tests including Mantel tests, Reduced Major Axis (RMA regression analysis, as well as calculate FST between all pairs of populations and perform basic summary statistics (e.g., heterozygosity. All statistical results, including publication-quality scatter plots in Postscript format, are returned rapidly to the user and can be easily downloaded. Conclusion IBDWS population genetics analysis software is hosted at http://phage.sdsu.edu/~jensen/ and documentation is available at http://www.bio.sdsu.edu/pub/andy/IBD.html. The source code has been made available on Source Forge at http://sourceforge.net/projects/ibdws/.

    Every research laboratory has a wealth of biomedical data locked up, which, if shared with other experts, could dramatically improve biomedical and healthcare research. With the PhysiomeSpace service, it is now possible with a few clicks to share with selected users biomedical data in an easy, controlled and safe way. The digital library service is managed using a client-server approach. The client application is used to import, fuse and enrich the data information according to the PhysiomeSpace resource ontology and upload/download the data to the library. The server services are hosted on the Biomed Town community portal, where through a web interface, the user can complete the metadata curation and share and/or publish the data resources. A search service capitalizes on the domain ontology and on the enrichment of metadata for each resource, providing a powerful discovery environment. Once the users have found the data resources they are interested in, they can add them to their basket, following a metaphor popular in e-commerce web sites. When all the necessary resources have been selected, the user can download the basket contents into the client application. The digital library service is now in beta and open to the biomedical research community.

    Full Text Available Abstract Background To aid in bioinformatics data processing and analysis, an increasing number of web-based applications are being deployed. Although this is a positive circumstance in general, the proliferation of tools makes it difficult to find the right tool, or more importantly, the right set of tools that can work together to solve real complex problems. Results Magallanes (Magellan is a versatile, platform-independent Java library of algorithms aimed at discovering bioinformatics web services and associated data types. A second important feature of Magallanes is its ability to connect available and compatible web services into workflows that can process data sequentially to reach a desired output given a particular input. Magallanes' capabilities can be exploited both as an API or directly accessed through a graphic user interface. The Magallanes' API is freely available for academic use, and together with Magallanes application has been tested in MS-Windows™ XP and Unix-like operating systems. Detailed implementation information, including user manuals and tutorials, is available at http://www.bitlab-es.com/magallanes. Conclusion Different implementations of the same client (web page, desktop applications, web services, etc. have been deployed and are currently in use in real installations such as the National Institute of Bioinformatics (Spain and the ACGT-EU project. This shows the potential utility and versatility of the software library, including the integration of novel tools in the domain and with strong evidences in the line of facilitate the automatic discovering and composition of workflows.

    WANG Leichun; GUAN Jihong; ZHOU Shuigeng

    2004-01-01

    In recent years, Web services and Peer-to-Peer (or simply P2P) appear as two of the hottest research topics in network computing. On the one hand, by adopting a decentralized, network-based style, P2P technologies can make P2P systems enhance overall reliability and fault-tolerance, increase autonomy, and enable ad-hoc communication and collaboration. On the other hand, Web services provides a good approach to integrate various heterogeneous systems and applications into a cooperative environment. This paper presents the techniques of combining Web services and P2P technologies into GIS to construct a new generation of GIS, which is more flexible and cooperative. As a case study, an ongoing project JGWS is introduced, which is an experimental GIS Web services platform built on JXTA. This paper also explores the schemes of building GIS Web services in a P2P environment.

  1. Correlated Topic Model for Web Services Ranking

    Directory of Open Access Journals (Sweden)

    Mustapha AZNAG

    2013-07-01

    Full Text Available With the increasing number of published Web services providing similar functionalities, it’s very tedious for a service consumer to make decision to select the appropriate one according to her/his needs. In this paper, we explore several probabilistic topic models: Probabilistic Latent Semantic Analysis (PLSA, Latent Dirichlet Allocation (LDA and Correlated Topic Model (CTM to extract latent factors from web service descriptions. In our approach, topic models are used as efficient dimension reduction techniques, which are able to capture semantic relationships between word-topic and topic-service interpreted in terms of probability distributions. To address the limitation of keywords-based queries, we represent web service description as a vector space and we introduce a new approach for discovering and ranking web services using latent factors. In our experiment, we evaluated our Service Discovery and Ranking approach by calculating the precision (P@n and normalized discounted cumulative gain (NDCGn.

  2. MAPI: towards the integrated exploitation of bioinformatics Web Services

    2011-10-01

    Full Text Available Abstract Background Bioinformatics is commonly featured as a well assorted list of available web resources. Although diversity of services is positive in general, the proliferation of tools, their dispersion and heterogeneity complicate the integrated exploitation of such data processing capacity. Results To facilitate the construction of software clients and make integrated use of this variety of tools, we present a modular programmatic application interface (MAPI that provides the necessary functionality for uniform representation of Web Services metadata descriptors including their management and invocation protocols of the services which they represent. This document describes the main functionality of the framework and how it can be used to facilitate the deployment of new software under a unified structure of bioinformatics Web Services. A notable feature of MAPI is the modular organization of the functionality into different modules associated with specific tasks. This means that only the modules needed for the client have to be installed, and that the module functionality can be extended without the need for re-writing the software client. Conclusions The potential utility and versatility of the software library has been demonstrated by the implementation of several currently available clients that cover different aspects of integrated data processing, ranging from service discovery to service invocation with advanced features such as workflows composition and asynchronous services calls to multiple types of Web Services including those registered in repositories (e.g. GRID-based, SOAP, BioMOBY, R-bioconductor, and others.

  7. Efficient Web Services Policy Combination

    Science.gov (United States)

    Vatan, Farrokh; Harman, Joseph G.

    2010-01-01

    Large-scale Web security systems usually involve cooperation between domains with non-identical policies. The network management and Web communication software used by the different organizations presents a stumbling block. Many of the tools used by the various divisions do not have the ability to communicate network management data with each other. At best, this means that manual human intervention into the communication protocols used at various network routers and endpoints is required. Developing practical, sound, and automated ways to compose policies to bridge these differences is a long-standing problem. One of the key subtleties is the need to deal with inconsistencies and defaults where one organization proposes a rule on a particular feature, and another has a different rule or expresses no rule. A general approach is to assign priorities to rules and observe the rules with the highest priorities when there are conflicts. The present methods have inherent inefficiency, which heavily restrict their practical applications. A new, efficient algorithm combines policies utilized for Web services. The method is based on an algorithm that allows an automatic and scalable composition of security policies between multiple organizations. It is based on defeasible policy composition, a promising approach for finding conflicts and resolving priorities between rules. In the general case, policy negotiation is an intractable problem. A promising method, suggested in the literature, is when policies are represented in defeasible logic, and composition is based on rules for non-monotonic inference. In this system, policy writers construct metapolicies describing both the policy that they wish to enforce and annotations describing their composition preferences. These annotations can indicate whether certain policy assertions are required by the policy writer or, if not, under what circumstances the policy writer is willing to compromise and allow other assertions to take

    Huang, Maojun

    2007-11-01

    Web map is the hybrid of map and the World Wide Web (known as Web). It is usually created with WebGIS techniques. With the rapid social development, web maps oriented the public are facing pressure that dissatisfy the increased demanding. The geocoding database plays a key role in supporting query services effectively. The traditional geocoding method is laborious and time-consuming. And there is much online spatial information, which would be the supplementary information source for geocoding. Therefore, this paper discusses how to improve query services by web mining. The improvement can be described from three facets: first, improving location query by discovering and extracting address information from the Web to extend geocoding database. Second, enhancing the ability of optimum path query of public traffic and buffer query by spatial analyzing and reasoning on the extended geocoding database. Third, adjusting strategies of collecting data according to patterns discovered by web map query mining. Finally, this paper presents the designing of the application system and experimental results.

    Directory of Open Access Journals (Sweden)

    Marlena Siwiak

    Full Text Available Although translation is the key step during gene expression, it remains poorly characterized at the level of individual genes. For this reason, we developed Transimulation - a web service measuring translational activity of genes in three model organisms: Escherichia coli, Saccharomyces cerevisiae and Homo sapiens. The calculations are based on our previous computational model of translation and experimental data sets. Transimulation quantifies mean translation initiation and elongation time (expressed in SI units, and the number of proteins produced per transcript. It also approximates the number of ribosomes that typically occupy a transcript during translation, and simulates their propagation. The simulation of ribosomes' movement is interactive and allows modifying the coding sequence on the fly. It also enables uploading any coding sequence and simulating its translation in one of three model organisms. In such a case, ribosomes propagate according to mean codon elongation times of the host organism, which may prove useful for heterologous expression. Transimulation was used to examine evolutionary conservation of translational parameters of orthologous genes. Transimulation may be accessed at http://nexus.ibb.waw.pl/Transimulation (requires Java version 1.7 or higher.

    2008-11-01

    Running TRANSP between NSTX shots requires rapid data preparation and job submittal. A web service with a graphical user interface and data visualization has been developed to meet these goals. The underlying data preparation system has a command line interface written in Python and runs on a PPPL compute server. The display client is a Java program (ElVis) that sends requests to the data preparation system. As the run data is prepared, graphs are created and sent to the client for display. Flux surface plots are displayed and animated over time. The most commonly used control options are implemented in the UI as buttons and text fields. A time slice or time dependent run can be prepared. The command line interface is available in the client program for expert users to apply advanced settings, to prototype new UI buttons, and to run scripts. The client program contains a simple text editor for modifying the TRANSP namelist. When data preparation is complete the run is submitted to the TRANSP production system. The initial version has been deployed and is being tested in the control room setting. Results will be discussed in the poster presentation. Work performed at PPPL under the auspices of U.S. DOE Contract DE-AC02-76CH03073.

  5. Domain-specific Web Service Discovery with Service Class Descriptions

    Energy Technology Data Exchange (ETDEWEB)

    Rocco, D; Caverlee, J; Liu, L; Critchlow, T J

    2005-02-14

    This paper presents DynaBot, a domain-specific web service discovery system. The core idea of the DynaBot service discovery system is to use domain-specific service class descriptions powered by an intelligent Deep Web crawler. In contrast to current registry-based service discovery systems--like the several available UDDI registries--DynaBot promotes focused crawling of the Deep Web of services and discovers candidate services that are relevant to the domain of interest. It uses intelligent filtering algorithms to match services found by focused crawling with the domain-specific service class descriptions. We demonstrate the capability of DynaBot through the BLAST service discovery scenario and describe our initial experience with DynaBot.

    2008-06-01

    Full Text Available One can hardly find any aspect of human life that has not been affected one way or another by the Internet. Most of the Internet’s impact is because of the changes it has brought about in the areas of communication and availability of information. Facilitating information availability and information communication are among core activities of libraries. Since the advent of the Internet, libraries have tried to adopt this technology and make the best of it for their services. The Internet has been considered by librarians both as a source of concern and as a gate to fascinating opportunities. It is of much interest to see how librarians have reacted to this technology in its early days and how they have perceived it and made effort to apply it in their libraries. The book ‘American Libraries and the Internet’ by Bin Li, a research-based book, aims to answer questions such as: how do librarians define their roles in the changing environment? How do they understand and appropriate the Web in their profession and workplace? How have they perceived the World Wide Web from its early period of its implementation? And finally how the Web is appropriated and used in libraries?

  10. Cross Support Transfer Service (CSTS) Framework Library

    Science.gov (United States)

    Ray, Timothy

    2014-01-01

    Within the Consultative Committee for Space Data Systems (CCSDS), there is an effort to standardize data transfer between ground stations and control centers. CCSDS plans to publish a collection of transfer services that will each address the transfer of a particular type of data (e.g., tracking data). These services will be called Cross Support Transfer Services (CSTSs). All of these services will make use of a common foundation that is called the CSTS Framework. This library implements the User side of the CSTS Framework. "User side" means that the library performs the role that is typically expected of the control center. This library was developed in support of the Goddard Data Standards program. This technology could be applicable for control centers, and possibly for use in control center simulators needed to test ground station capabilities. The main advantages of this implementation are its flexibility and simplicity. It provides the framework capabilities, while allowing the library user to provide a wrapper that adapts the library to any particular environment. The main purpose of this implementation was to support the inter-operability testing required by CCSDS. In addition, it is likely that the implementation will be useful within the Goddard mission community (for use in control centers).

It identifies a number of methodologies and opportunities that are open to libraries and takes the view that it is never wise to waste a good crisis, because all threats are really opportunities in disguise. The article looks at the initial economic context for European research libraries and then examines ways in which libraries can tackle the threats which the current financial crisis poses. Joint procurement is one way in which libraries can achieve value for money, and the paper examines the role of JIS C Collections in the UK. Innovation through collaboration and shared services are also ways in which libraries can innovate/make savings in a cost-effective way by sharing the burden of costs around the partnership. The paper gives two examples: one which is now well established, the DART-Europe portal for Open Access e-theses; and one which is in the early stages of being discussed — a cloud-based solution for true collaborative cataloguing amongst the UK’s research and national libraries.

  13. A Semantic Matchmaker for Ranking Web Services

    Institute of Scientific and Technical Information of China (English)

    Bin Xu; Po Zhang; Juan-Zi Li; Wen-Jun Yang

    2006-01-01

    This paper is concerned with the matchmaker for ranking web services by using semantics. So far several methods of semantic matchmaker have been proposed. Most of them, however, focus on classifying the services into predefined categories rather than providing a ranking result. In this paper, a new method of semantic matchmaker is proposed for ranking web services. It is proposed to use the semantic distance for estimating the matching degree between a service and a user request. Four types of semantic distances are defined and four algorithms are implemented respectively to calculate them. Experimental results show that the proposed semantic matchmaker significantly outperforms the keywordbased baseline method.

    2012-09-01

    Full Text Available The recent introduction of the WebGL API for leveraging the power of 3D graphics accelerators within Web browsers opens the possibility to develop advanced graphics applications without the need for an ad-hoc plug-in. There are several contexts in which this new technology can be exploited to enhance user experience and data fruition, like e-commerce applications, games and, in particular, Cultural Heritage. In fact, it is now possible to use the Web platform to present a virtual reconstruction hypothesis of ancient pasts, to show detailed 3D models of artefacts of interests to a wide public, and to create virtual museums. We introduce SpiderGL, a JavaScript library for developing 3D graphics Web applications. SpiderGL provides data structures and algorithms to ease the use of WebGL, to define and manipulate shapes, to import 3D models in various formats, and to handle asynchronous data loading. We show the potential of this novel library with a number of demo applications and give details about its future uses in the context of Cultural Heritage applications.

    ESO Reflex is a prototype graphical workflow system, based on Taverna, and primarily intended to be a flexible way of running ESO data reduction recipes along with other legacy applications and user-written tools. ESO Reflex can also readily use the Taverna Web Services features that are based on the Apache Axis SOAP implementation. Taverna is a general purpose Web Service client, and requires no programming to use such services. However, Taverna also has some restrictions: for example, no numerical types such integers. In addition the preferred binding style is document/literal wrapped, but most astronomical services publish the Axis default WSDL using RPC/encoded style. Despite these minor limitations we have created simple but very promising test VO workflow using the Sesame name resolver service at CDS Strasbourg, the Hubble SIAP server at the Multi-Mission Archive at Space Telescope (MAST) and the WESIX image cataloging and catalogue cross-referencing service at the University of Pittsburgh. ESO Reflex can also pass files and URIs via the PLASTIC protocol to visualisation tools and has its own viewer for VOTables. We picked these three Web Services to try to set up a realistic and useful ESO Reflex workflow. They also demonstrate ESO Reflex abilities to use many kind of Web Services because each of them requires a different interface. We describe each of these services in turn and comment on how it was used

    U-Compare is a text mining platform that allows the construction, evaluation and comparison of text mining workflows. U-Compare contains a large library of components that are tuned to the biomedical domain. Users can rapidly develop biomedical text mining workflows by mixing and matching U-Compare's components. Workflows developed using U-Compare can be exported and sent to other users who, in turn, can import and re-use them. However, the resulting workflows are standalone applications, i.e., software tools that run and are accessible only via a local machine, and that can only be run with the U-Compare platform. We address the above issues by extending U-Compare to convert standalone workflows into web services automatically, via a two-click process. The resulting web services can be registered on a central server and made publicly available. Alternatively, users can make web services available on their own servers, after installing the web application framework, which is part of the extension to U-Compare. We have performed a user-oriented evaluation of the proposed extension, by asking users who have tested the enhanced functionality of U-Compare to complete questionnaires that assess its functionality, reliability, usability, efficiency and maintainability. The results obtained reveal that the new functionality is well received by users. The web services produced by U-Compare are built on top of open standards, i.e., REST and SOAP protocols, and therefore, they are decoupled from the underlying platform. Exported workflows can be integrated with any application that supports these open standards. We demonstrate how the newly extended U-Compare enhances the cross-platform interoperability of workflows, by seamlessly importing a number of text mining workflow web services exported from U-Compare into Taverna, i.e., a generic scientific workflow construction platform.

  3. BOWS (bioinformatics open web services) to centralize bioinformatics tools in web services.

    2015-06-02

    Bioinformaticians face a range of difficulties to get locally-installed tools running and producing results; they would greatly benefit from a system that could centralize most of the tools, using an easy interface for input and output. Web services, due to their universal nature and widely known interface, constitute a very good option to achieve this goal. Bioinformatics open web services (BOWS) is a system based on generic web services produced to allow programmatic access to applications running on high-performance computing (HPC) clusters. BOWS intermediates the access to registered tools by providing front-end and back-end web services. Programmers can install applications in HPC clusters in any programming language and use the back-end service to check for new jobs and their parameters, and then to send the results to BOWS. Programs running in simple computers consume the BOWS front-end service to submit new processes and read results. BOWS compiles Java clients, which encapsulate the front-end web service requisitions, and automatically creates a web page that disposes the registered applications and clients. Bioinformatics open web services registered applications can be accessed from virtually any programming language through web services, or using standard java clients. The back-end can run in HPC clusters, allowing bioinformaticians to remotely run high-processing demand applications directly from their machines.

    2010-07-01

    Biomedical applications have become increasingly complex, and they often require large-scale high-performance computing resources with a large number of processors and memory. The complexity of application deployment and the advances in cluster, grid and cloud computing require new modes of support for biomedical research. Scientific Software as a Service (sSaaS) enables scalable and transparent access to biomedical applications through simple standards-based Web interfaces. Towards this end, we built a production web server (http://ws.nbcr.net) in August 2007 to support the bioinformatics application called MEME. The server has grown since to include docking analysis with AutoDock and AutoDock Vina, electrostatic calculations using PDB2PQR and APBS, and off-target analysis using SMAP. All the applications on the servers are powered by Opal, a toolkit that allows users to wrap scientific applications easily as web services without any modification to the scientific codes, by writing simple XML configuration files. Opal allows both web forms-based access and programmatic access of all our applications. The Opal toolkit currently supports SOAP-based Web service access to a number of popular applications from the National Biomedical Computation Resource (NBCR) and affiliated collaborative and service projects. In addition, Opal's programmatic access capability allows our applications to be accessed through many workflow tools, including Vision, Kepler, Nimrod/K and VisTrails. From mid-August 2007 to the end of 2009, we have successfully executed 239,814 jobs. The number of successfully executed jobs more than doubled from 205 to 411 per day between 2008 and 2009. The Opal-enabled service model is useful for a wide range of applications. It provides for interoperation with other applications with Web Service interfaces, and allows application developers to focus on the scientific tool and workflow development.

    Full Text Available Evaluating the e-service quality is essential to organizations. The future of e-libraries has a vital place in universities. Libraries need to use websites as means to provide access to information resources, news and events. The importance of assessing e-service quality of libraries is significant. Previous researchers have developed many methods for assessing e-service quality. However, most of them only focus on the independent hierarchical structure. In this paper, we would like to figure out the criteria for assessing the service quality of library websites from university students’ viewpoints. According to interdependent criteria, the analytic network process (ANP approach is employed to (i generate the priority weights of each criterion; (ii measure the service quality of university library websites. 12 web-based service criteria are identified according to 3144 university students’ viewpoints based on fuzzy Delphi method. On the basis of past studies, we divide 12 criteria into 3 perspectives, namely, system, efficiency, and information quality to measure the service quality of university library websites. On the basis of 3 perspectives and 12 important criteria, service quality of university library websites could be measured more effectively. Moreover, the practical application to measure the service quality of the old and new versions of one university library website presented in Section 5 is generic and also suitable to be exploited for Taiwanese universities.

    Full Text Available The veracity and secrecy of medical information which is transacted over the Internet is vulnerable to attack. But the transaction of such details is mandatory in order to avail the luxury of medical services anywhere, anytime. Especially in a web service enabled system for hospital management, it becomes necessary to address these security issues. It is mandatory that the services guarantee message delivery to software applications, with a chosen level of quality of service (QoS. This paper presents a VDM++ based specification for modelling a security framework for web services with non repudiation to ensure that a party in a dispute cannot repudiate, or refute the validity of a statement or contract and it is ensured that the transaction happens in a reliable manner. This model presents the procedure and technical options to have a secure communication over Internet with web services. Based on the model the Medi - Helper is developed to use the technologies of WS-Security, WS-Reliability and WS-Policy, WSRN in order to create encrypted messages so that the Patient’s medical records are not tampered with when relayed over Internet, and are sent in a reliable manner.

    Geospatial Catalogue Web Service is a vital service for sharing and interoperating volumes of distributed heterogeneous geospatial resources, such as data, services, applications, and their replicas over the web. Based on the Grid technology and the Open Geospatial Consortium (0GC) s Catalogue Service - Web Information Model, this paper proposes a new information model for Geospatial Catalogue Web Service, named as GCWS which can securely provides Grid-based publishing, managing and querying geospatial data and services, and the transparent access to the replica data and related services under the Grid environment. This information model integrates the information model of the Grid Replica Location Service (RLS)/Monitoring & Discovery Service (MDS) with the information model of OGC Catalogue Service (CSW), and refers to the geospatial data metadata standards from IS0 19115, FGDC and NASA EOS Core System and service metadata standards from IS0 191 19 to extend itself for expressing geospatial resources. Using GCWS, any valid geospatial user, who belongs to an authorized Virtual Organization (VO), can securely publish and manage geospatial resources, especially query on-demand data in the virtual community and get back it through the data-related services which provide functions such as subsetting, reformatting, reprojection etc. This work facilitates the geospatial resources sharing and interoperating under the Grid environment, and implements geospatial resources Grid enabled and Grid technologies geospatial enabled. It 2!so makes researcher to focus on science, 2nd not cn issues with computing ability, data locztic, processir,g and management.

    2012-04-01

    Full Text Available Semantic Web Services (SWS are Web Service (WS descriptions augmented with semantic information. SWS enable intelligent reasoning and automation in areas such as service discovery, composition, mediation, ranking and invocation. This paper applies SWS to a previous protocol adapter which, operating within clearly defined constraints, maps SOAP Web Services to RESTful HTTP format. However, in the previous adapter, the configuration element is manual and the latency implications are locally based. This paper applies SWS technologies to automate the configuration element and the latency tests are conducted in a more realistic Internet based setting.

    2007-01-01

    An effective assemble-oriented framework for grid Web service based on open grid service architecture was proposed, in which Web service semantics network constructed by software reuse was designed to enhance the locating of assemble-oriented service resources. The successful Web services assembled structure was exploited to design semantics network, the logical and the physical structure of the resource was separated in Web service, and the logical resource derived from type ID of Web service was combined. Experiment results show that the success ratio of Web service request comes to 100% while providing completely assembly semantics set. This model provides guarantee of the reliability of assemble Web service and establishes the foundation of web service automatic interaction, customizing application service and dynamic service configuration.

  11. Web Service Interface for Data Collection

    Directory of Open Access Journals (Sweden)

    Ruchika

    2012-05-01

    Full Text Available Data collection is a key component of an information system. The widespread penetration of ICT tools in organizations and institutions has resulted in a shift in the way the data is collected. Data may be collected in printed-form, by e-mails, on a compact disk, or, by direct upload on the management information system. Since web services are platform-independent, it can access data stored in the XML format from any platform. In this paper, we present an interface which uses web services for data collection. It requires interaction between a web service deployed for the purposes of data collection, and the web address where the data is stored. Our interface requires that the web service has pre-knowledge of the address from where the data is to be collected. Also, the data to be accessed must be stored in XML format. Since our interface uses computer-supported interaction on both sides, it eases the task of regular and ongoing data collection. We apply our framework to the Education Management Information System, which collects data from schools spread across the country.

    2013-01-01

    Libraries in the USA and globally are undergoing quiet revolution. Libraries are moving away from a philosophy that is collection-centered to one focused on service. Technology is key to that change. The Patron Driven Library explores the way technology has moved the focus from library collections to services, placing the reader at the center of library activities. The book reveals the way library users are changing, and how social networking, web delivery of information, and the uncertain landscape of e-print has energized librarians to adopt technology to meet a different model of the library while preserving core values. Following an introduction, the first part begins with the historical milieu, and moves on to current challenges for financing and acquiring materials, and an exploration of why the millennial generation is transformational. The second part examines how changes in library practice can create a culture for imagining library services in an age of information overflow. The final chapter asks: ...

  20. RECOMMENDATION FOR WEB SERVICE COMPOSITION BY MINING USAGE LOGS

    Directory of Open Access Journals (Sweden)

    Vivek R

    2016-03-01

    Full Text Available Web service composition has been one of the most researched topics of the past decade. Novel methods of web service composition are being proposed in the literature include Semantics-based composition, WSDLbased composition. Although these methods provide promising results for composition, search and discovery of web service based on QoS parameter of network and semantics or ontology associated with WSDL, they do not address composition based on usage of web service. Web Service usage logs capture time series data of web service invocation by business objects, which innately captures patterns or workflows associated with business operations. Web service composition based on such patterns and workflows can greatly streamline the business operations. In this research work, we try to explore and implement methods of mining web service usage logs. Main objectives include Identifying usage association of services. Linking one service invocation with other, Evaluation of the causal relationship between associations of services.

  1. Data as a Service: A Seismic Web Service Pipeline

    Science.gov (United States)

    Martinez, E.

    2016-12-01

    Publishing data as a service pipeline provides an improved, dynamic approach over static data archives. A service pipeline is a collection of micro web services that each perform a specific task and expose the results of that task. Structured request/response formats allow micro web services to be chained together into a service pipeline to provide more complex results. The U.S. Geological Survey adopted service pipelines to publish seismic hazard and design data supporting both specific and generalized audiences. The seismic web service pipeline starts at source data and exposes probability and deterministic hazard curves, response spectra, risk-targeted ground motions, and seismic design provision metadata. This pipeline supports public/private organizations and individual engineers/researchers. Publishing data as a service pipeline provides a variety of benefits. Exposing the component services enables advanced users to inspect or use the data at each processing step. Exposing a composite service enables new users quick access to published data with a very low barrier to entry. Advanced users may re-use micro web services by chaining them in new ways or injecting new micros services into the pipeline. This allows the user to test hypothesis and compare their results to published results. Exposing data at each step in the pipeline enables users to review and validate the data and process more quickly and accurately. Making the source code open source, per USGS policy, further enables this transparency. Each micro service may be scaled independent of any other micro service. This ensures data remains available and timely in a cost-effective manner regardless of load. Additionally, if a new or more efficient approach to processing the data is discovered, this new approach may replace the old approach at any time, keeping the pipeline running while not affecting other micro services.

  3. Evolution of web services in bioinformatics.

    Science.gov (United States)

    Neerincx, Pieter B T; Leunissen, Jack A M

    2005-06-01

    Bioinformaticians have developed large collections of tools to make sense of the rapidly growing pool of molecular biological data. Biological systems tend to be complex and in order to understand them, it is often necessary to link many data sets and use more than one tool. Therefore, bioinformaticians have experimented with several strategies to try to integrate data sets and tools. Owing to the lack of standards for data sets and the interfaces of the tools this is not a trivial task. Over the past few years building services with web-based interfaces has become a popular way of sharing the data and tools that have resulted from many bioinformatics projects. This paper discusses the interoperability problem and how web services are being used to try to solve it, resulting in the evolution of tools with web interfaces from HTML/web form-based tools not suited for automatic workflow generation to a dynamic network of XML-based web services that can easily be used to create pipelines.

    As more Earth science software tools and services move to the web--the design and usability of those tools become ever more important. A good user interface is becoming expected and users are becoming increasingly intolerant of websites and web applications that work against them. The Earthdata UI Pattern Library attempts to give these scientists and developers the design tools they need to make usable, compelling user interfaces without the associated overhead of using a full design team. Patterns are tested and functional user interface elements targeted specifically at the Earth science community and will include web layouts, buttons, tables, typography, iconography, mapping and visualization/graphing widgets. These UI elements have emerged as the result of extensive user testing, research and software development within the NASA Earthdata team over the past year.

  8. QOS Aware Formalized Model for Semantic Web Service Selection

    Directory of Open Access Journals (Sweden)

    Divya Sachan

    2014-10-01

    Full Text Available Selecting the most relevant Web Service according to a client requirement is an onerous task, as innumerous number of functionally same Web Services(WS are listed in UDDI registry. WS are functionally same but their Quality and performance varies as per service providers. A web Service Selection Process involves two major points: Recommending the pertinent Web Service and avoiding unjustifiable web service. The deficiency in keyword based searching is that it doesn’t handle the client request accurately as keyword may have ambiguous meaning on different scenarios. UDDI and search engines all are based on keyword search, which are lagging behind on pertinent Web service selection. So the search mechanism must be incorporated with the Semantic behavior of Web Services. In order to strengthen this approach, the proposed model is incorporated with Quality of Services (QoS based Ranking of semantic web services.

  9. Smart: Semantically Mashup Rest Web Services

    Directory of Open Access Journals (Sweden)

    Rima Kilany

    2013-10-01

    Full Text Available A mashup is a combination of information from more than one source, mixed up in a way to create something new, or at least useful. Anyone can find mashups on the internet, but these are always specifically designed for a predefined purpose. To change that fact, we implemented a new platform we called the SMART platform. SMART enables the user to make his own choices as for the REST web services he needs to call in order to build an intelligent personalized mashup, from a Google-like simple search interface, without needing any programming skills. In order to achieve this goal, we defined an ontology that can hold REST web services descriptions. These descriptions encapsulate mainly, the input type needed for a service, its output type, and the kind of relation that ties the input to the output. Then, by matching the user input query keywords, with the REST web services definitions in our ontology, we can find registered services individuals in this ontology, and construct the raw REST query for each service found. The wrap up from the keywords, into semantic definitions, in order to find the matching service individual, then the wrap down from the semantic service description of the found individual, to the raw REST call, and finally the wrap up of the result again into semantic individuals, is done for two main purposes: the first to let the user use simple keywords in order to build complex mashups, and the second to benefit from the ontology’s inference engine in a way, where services instances can be tied together into an intelligent mashup, simply by making each service output individuals, stand as the next service input.

  15. Library 2.0, information and digital literacies in the light of the contradictory nature of Web 2.0

    Directory of Open Access Journals (Sweden)

    Tibor Koltay

    2010-12-01

    Full Text Available Desk research was done to examine the importance of raising awareness of differences between professional content and content produced by the amateurs of the Web 2.0. The commercial nature of Web 2.0 was briefly explained. Questions related to amateurism have been raised and amateur contents characterizing Web 2.0 were contrasted to professional ones. The results show that some principles can be laid down. First of all, the need in literacies of students, teaching staff and researchers is different from that of other categories of users, when the former are fulfilling their professional roles. These needs can be satisfied mainly by services that traditionally have been provided by academic and special libraries, while making use of Web 2.0 tools could mean moving towards the goals of public library users. Second, information literacy and digital literacy alongside with adequately defined Library 2.0 are expedient in the era of Web 2.0 to support user needs by the provision of appropriate library resources and services.

    High Energy Physics (HEP) and other scientific communities have adopted Service Oriented Architectures (SOA) as part of a larger Grid computing effort. This effort involves the integration of many legacy applications and programming libraries into a SOA framework. The Grid Analysis Environment (GAE) is such a service oriented architecture based on the Clarens Grid Services Framework and is being developed as part of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at European Laboratory for Particle Physics (CERN). Clarens provides a set of authorization, access control, and discovery services, as well as XMLRPC and SOAP access to all deployed services. Two implementations of the Clarens Web Services Framework (Python and Java) offer integration possibilities for a wide range of programming languages. This paper describes the Java implementation of the Clarens Web Services Framework called JClarens. and several web services of interest to the scientific and Grid community that hav...

  18. A Service Design Oriented Web Services Composite Platform

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    In order to realize flexible, adaptable, extensible, efficient, and user-friendly service composition, we propose a service design oriented Web Service composite platform (SDOWSCP) and a service composition mechanism called composed-service-requestor-oriented service composition (OBSDOSC). SDOWSCP imports ontology into UDDI to define and annotate services in a flexible and intuitive manner and employs a concept of bond as a solution to the process heterogeneity. OBSDOSC is proposed in order to do some efforts to overcome some defects which current design tools usually have such as not user-friendly and too professional. This paper proposes a pattern which describes the basic features of semi-automatic composite mode, discusses the whole lifetime of composed service and highlights how to lessen the descriptive heterogeneity and process heterogeneity and how to facilitate the design of composing a service.

  19. Focused Crawling of the Deep Web Using Service Class Descriptions

    Energy Technology Data Exchange (ETDEWEB)

    Rocco, D; Liu, L; Critchlow, T

    2004-06-21

    Dynamic Web data sources--sometimes known collectively as the Deep Web--increase the utility of the Web by providing intuitive access to data repositories anywhere that Web access is available. Deep Web services provide access to real-time information, like entertainment event listings, or present a Web interface to large databases or other data repositories. Recent studies suggest that the size and growth rate of the dynamic Web greatly exceed that of the static Web, yet dynamic content is often ignored by existing search engine indexers owing to the technical challenges that arise when attempting to search the Deep Web. To address these challenges, we present DynaBot, a service-centric crawler for discovering and clustering Deep Web sources offering dynamic content. DynaBot has three unique characteristics. First, DynaBot utilizes a service class model of the Web implemented through the construction of service class descriptions (SCDs). Second, DynaBot employs a modular, self-tuning system architecture for focused crawling of the DeepWeb using service class descriptions. Third, DynaBot incorporates methods and algorithms for efficient probing of the Deep Web and for discovering and clustering Deep Web sources and services through SCD-based service matching analysis. Our experimental results demonstrate the effectiveness of the service class discovery, probing, and matching algorithms and suggest techniques for efficiently managing service discovery in the face of the immense scale of the Deep Web.

    The Tasmanian Partnership for Advanced Computing (TPAC) has developed a rich web-based application that publishes large catalogs of scientific datasets. The TPAC Digital Library provides a user interface for viewing, searching, and accessing the catalog data collections, as well as enabling data services for user access. The product also provides management functions for librarians of digital data collections. The search features allow files to be selected graphically based on geospatial extent, or by file name, variable name, attribute value, and by tag. Alternatively, there is a file manager style interface that provides a direct route to the data. The interface is specifically geared towards discovery and access of earth science data files, which makes it intuitive and easy to navigate. Files can be downloaded, or accessed through OPeNDAP, GridFTP, WCS, Matlab and other interfaces. The digital library can harvest metadata from THREDDS, Hyrax, IPCC catalogs and other instances of the digital library. The product is freely available under an open-source license, and is currently deployed by a small but active user base. It has existed since 2005, and remains under constant development by TPAC and other contributors (including the Australian Bureau of Meteorology). Current development initiatives will allow interoperability with library service protocols, as well as other data archive organizations and scientific bodies for data reference transparency. There is a project in progress that will allow the data collection’s owner to attach attribute information, access rights, and meta-data to the data collection to conform to various user community and service standards. Future releases will allow publishers to attach media rich information about the data collection, as well as additional information about scientific results, and papers and web pages that reference the data collection. The presentation will discuss the current implementation, and future directions.

    2015-12-01

    Both the National Research Council Decadal Survey and the latest Intergovernmental Panel on Climate Change Assessment Report stressed the need for the comprehensive and innovative evaluation of climate models with the synergistic use of global satellite observations in order to improve our weather and climate simulation and prediction capabilities. The abundance of satellite observations for fundamental climate parameters and the availability of coordinated model outputs from CMIP5 for the same parameters offer a great opportunity to understand and diagnose model biases in climate models. In addition, the Obs4MIPs efforts have created several key global observational datasets that are readily usable for model evaluations. However, a model diagnostic evaluation process requires physics-based multi-variable comparisons that typically involve large-volume and heterogeneous datasets, making them both computationally- and data-intensive. In response, we have developed a novel methodology to diagnose model biases in contemporary climate models and implementing the methodology as a web-service based, cloud-enabled, provenance-supported climate-model evaluation system. The evaluation system is named Climate Model Diagnostic Analyzer (CMDA), which is the product of the research and technology development investments of several current and past NASA ROSES programs. The current technologies and infrastructure of CMDA are designed and selected to address several technical challenges that the Earth science modeling and model analysis community faces in evaluating and diagnosing climate models. In particular, we have three key technology components: (1) diagnostic analysis methodology; (2) web-service based, cloud-enabled technology; (3) provenance-supported technology. The diagnostic analysis methodology includes random forest feature importance ranking, conditional probability distribution function, conditional sampling, and time-lagged correlation map. We have implemented the

    Lee, S.; Pan, L.; Zhai, C.; Tang, B.; Jiang, J. H.

    2014-12-01

    We have developed a cloud-enabled web-service system that empowers physics-based, multi-variable model performance evaluations and diagnoses through the comprehensive and synergistic use of multiple observational data, reanalysis data, and model outputs. We have developed a methodology to transform an existing science application code into a web service using a Python wrapper interface and Python web service frameworks. The web-service system, called Climate Model Diagnostic Analyzer (CMDA), currently supports (1) all the observational datasets from Obs4MIPs and a few ocean datasets from NOAA and Argo, which can serve as observation-based reference data for model evaluation, (2) many of CMIP5 model outputs covering a broad range of atmosphere, ocean, and land variables from the CMIP5 specific historical runs and AMIP runs, and (3) ECMWF reanalysis outputs for several environmental variables in order to supplement observational datasets. Analysis capabilities currently supported by CMDA are (1) the calculation of annual and seasonal means of physical variables, (2) the calculation of time evolution of the means in any specified geographical region, (3) the calculation of correlation between two variables, (4) the calculation of difference between two variables, and (5) the conditional sampling of one physical variable with respect to another variable. A web user interface is chosen for CMDA because it not only lowers the learning curve and removes the adoption barrier of the tool but also enables instantaneous use, avoiding the hassle of local software installation and environment incompatibility. CMDA will be used as an educational tool for the summer school organized by JPL's Center for Climate Science in 2014. In order to support 30+ simultaneous users during the school, we have deployed CMDA to the Amazon cloud environment. The cloud-enabled CMDA will provide each student with a virtual machine while the user interaction with the system will remain the same

    2014-08-01

    Full Text Available Web services allow communication between heterogeneous systems in a distributed environment. Their enormous success and their increased use led to the fact that thousands of Web services are present on the Internet. This significant number of Web services which not cease to increase has led to problems of the difficulty in locating and classifying web services, these problems are encountered mainly during the operations of web services discovery and substitution. Traditional ways of search based on keywords are not successful in this context, their results do not support the structure of Web services and they consider in their search only the identifiers of the web service description language (WSDL interface elements. The methods based on semantics (WSDLS, OWLS, SAWSDL… which increase the WSDL description of a Web service with a semantic description allow raising partially this problem, but their complexity and difficulty delays their adoption in real cases. Measuring the similarity between the web services interfaces is the most suitable solution for this kind of problems, it will classify available web services so as to know those that best match the searched profile and those that do not match. Thus, the main goal of this work is to study the degree of similarity between any two web services by offering a new method that is more effective than existing works.

    The purpose of Enterprise Application Integration (EAI) is to enable the interoperability between two or more enterprise software systems. These systems, for example, can be an Enterprise Resource Planning (ERP) system, an Enterprise Asset Management (EAM) system or a Condition Monitoring system. Traditional EAI approach, based on point-to-point connection, is expensive, vendor specific with limited modules and restricted interoperability with other ERPs and applications. To overcome these drawbacks, the Web Service based EAI has emerged. It allows the integration without point to point linking and with less costs. Many approaches of Web service based EAI are combined with ORACLE, SAP, PeopleSoft, WebSphere, SIEBEL etc. as a system integration platform. The approach still has the restriction that only predefined clients can access the services. This means clients must know exactly the protocol for calling the services and if they don't have the access information they never can get the services. This is because these Web services are based on syntactic service description. In this paper, a semantic based EAI approach, that allows the uninformed clients to access the services, is introduced. The semantic EAI is designed with the Web services that have semantic service descriptions. The Semantic Web Services(SWS) are described in Web Ontology Language for Services(OWL-S), a semantic service ontology language, and advertised in Universal Description, Discovery and Integration (UDDI). Clients find desired services through the UDDI and get services from service providers through Web Service Description Language(WSDL)

    2005-04-01

    It is a well-known fact that the retail industry always works on razorthin margins and the key to survival lies in optimization of resources both in space and time dimensions as well as maximization of customer satisfaction. Access to timely and even real-time information to a wide variety of channel and trading partners, sales personnel, line managers, store managers etc. is the key to achieving this. Web services technology holds out a lot of promise for the retail industry in this respect. It is a platform-neutral, easy to deploy set of standards for achieving business data and process integration, without going for proprietary point to point connections. It promises to connect the information providers and information consumers across a wide variety of platforms, devices and on an on-demand basis. Being based on service-oriented architecture (SOA) principles it can also form the enabling service interface layer for other emerging technologies like BAM, BPM, mobile and RFID. In this paper, we attempt to understand information-flow needs in the retail industry and also suggest a roadmap approach by which the retail enterprise could exploit the potential of web services at minimal risk.

  10. Pragmatic Computing - A Semiotic Perspective to Web Services

    Liu, Kecheng

    The web seems to have evolved from a syntactic web, a semantic web to a pragmatic web. This evolution conforms to the study of information and technology from the theory of semiotics. The pragmatics, concerning with the use of information in relation to the context and intended purposes, is extremely important in web service and applications. Much research in pragmatics has been carried out; but in the same time, attempts and solutions have led to some more questions. After reviewing the current work in pragmatic web, the paper presents a semiotic approach to website services, particularly on request decomposition and service aggregation.

    Lee, S.; Pan, L.; Zhai, C.; Tang, B.; Jiang, J. H.

    2013-12-01

    The latest Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report stressed the need for the comprehensive and innovative evaluation of climate models with newly available global observations. The traditional approach to climate model evaluation, which compares a single parameter at a time, identifies symptomatic model biases and errors but fails to diagnose the model problems. The model diagnosis process requires physics-based multi-variable comparisons that typically involve large-volume and heterogeneous datasets, making them both computationally- and data-intensive. To address these challenges, we are developing a parallel, distributed web-service system that enables the physics-based multi-variable model performance evaluations and diagnoses through the comprehensive and synergistic use of multiple observational data, reanalysis data, and model outputs. We have developed a methodology to transform an existing science application code into a web service using a Python wrapper interface and Python web service frameworks (i.e., Flask, Gunicorn, and Tornado). The web-service system, called Climate Model Diagnostic Analyzer (CMDA), currently supports (1) all the datasets from Obs4MIPs and a few ocean datasets from NOAA and Argo, which can serve as observation-based reference data for model evaluation and (2) many of CMIP5 model outputs covering a broad range of atmosphere, ocean, and land variables from the CMIP5 specific historical runs and AMIP runs. Analysis capabilities currently supported by CMDA are (1) the calculation of annual and seasonal means of physical variables, (2) the calculation of time evolution of the means in any specified geographical region, (3) the calculation of correlation between two variables, and (4) the calculation of difference between two variables. A web user interface is chosen for CMDA because it not only lowers the learning curve and removes the adoption barrier of the tool but also enables instantaneous use

    2016-07-01

    Full Text Available Purpose: A research was made into user satisfaction with regard to the quality of library services in one of the Slovenian public libraries. The aim was to establish the type of service quality level actually expected by the users, and to determine their satisfaction with the current quality level of available library services.Methodology: The research was performed by means of the SERVQUAL measuring tool which was used to determine the size and direction of the gap between the detected and the expected quality of library services among public library users.Results: Different groups of users provide different assessments of specific quality factors, and a library cannot satisfy the expectations of each and every user if most quality factors display discrepancies between the estimated perception and expectations. The users expect more reliable services and more qualified library staff members who would understand and allocate time for each user’s individual needs. The largest discrepancies from the expectations are detected among users in the under-35 age group and among the more experienced and skilled library users. The results of factor analysis confirm the fact that a higher number of quality factors can be explained by three common factors affecting the satisfaction of library users. A strong connection between user satisfaction and their assessment of the integral quality of services and loyalty has been established.Research restrictions: The research results should not be generalised and applied to all Slovenian public libraries since they differ in many important aspects. In addition, a non-random sampling method was used.Research originality/Applicability: The conducted research illustrates the use of a measuring tool that was developed with the aim of determining the satisfaction of users with the quality of library services in Slovenian public libraries. Keywords: public library, user satisfaction, quality of library services, user

    Full Text Available The purpose of this study is to improve library promotional marketing for the disabled by identifying requirements of public library disability services. This study aimed to investigate librarian service providers' awareness of library programs for the disabled in order to prepare a systematic plan for promoting such library services. Research methods used are a literature analysis and survey. First, the ratio of respondents with experience promoting activities and services for the disabled was less than 50%. Second, regarding methods for promoting library disability services, the respondents used library homepages, press releases, library user guides, library newsletters, and library pamphlets in that order. Third, when asked what kind of PR media the library disability service providers had experience with and how often they use it, library boards and banners were the most common response. Fourth, suggested improvements to the current design and content of PR materials included: clearer word choice (or greater understandability, more detailed descriptions, simpler layouts, and more interesting or eye-catching content in that order. Fifth, the library disability services which are in the most need of public relations were guide information for library disability services, Library and Information Service (DOI services and search services, using alternative materials and the library collection, and aiding the information search. Overall, when evaluating the promotion of disability services in Korea, the library's public relations for disabled services needs to improve because currently neither librarians nor the disabled community they are targeting has frequent or quality experience with it. Thus, the policy department for the library disability services must develop a variety of promotional strategies adjusted for each type of the disability and distribute PR materials to service providers individually, making sure to utilize effective PR

  13. The Semantics of Web Services: An Examination in GIScience Applications

    Directory of Open Access Journals (Sweden)

    Xuan Shi

    2013-09-01

    Full Text Available Web service is a technological solution for software interoperability that supports the seamless integration of diverse applications. In the vision of web service architecture, web services are described by the Web Service Description Language (WSDL, discovered through Universal Description, Discovery and Integration (UDDI and communicate by the Simple Object Access Protocol (SOAP. Such a divination has never been fully accomplished yet. Although it was criticized that WSDL only has a syntactic definition of web services, but was not semantic, prior initiatives in semantic web services did not establish a correct methodology to resolve the problem. This paper examines the distinction and relationship between the syntactic and semantic definitions for web services that characterize different purposes in service computation. Further, this paper proposes that the semantics of web service are neutral and independent from the service interface definition, data types and platform. Such a conclusion can be a universal law in software engineering and service computing. Several use cases in the GIScience application are examined in this paper, while the formalization of geospatial services needs to be constructed by the GIScience community towards a comprehensive ontology of the conceptual definitions and relationships for geospatial computation. Advancements in semantic web services research will happen in domain science applications.

    2011-07-01

    Full Text Available College students are accessing virtual libraries whether they are on campus or learning from a distance. Academic institutions serving virtual patrons must remain focused on meeting the needs of those library users by continually examining their preferences, their searching behavior, and the information they seek. The purpose of this research was to determine if virtual patrons are satisfied with the resources and services being provided by a university’s online library. Following a web-based survey, demographic characteristics of students were analyzed to determine if any influenced students’ satisfaction. Using analysis of variance, correlation, and descriptive statistics, several demographic factors were found to influence student satisfaction with the library’s online resources: age, gender, achieved educational level, student status, and computer experience. One factor, computer experience, was found to influence student satisfaction with the library’s online services.Overall, students reported satisfaction with the university’s online library resources and services. Comments submitted to open-ended questions regarding areas for improvement to the online library provide library administrators with avenues for development to increase awareness of library services, focus improvement in navigation, and enhance student satisfaction.

    Ukraine Virtual Observatory (UkrVO) has been a member of the International Virtual Observatory Alliance (IVOA) since 2011. The virtual observatory (VO) is not a magic solution to all problems of data storing and processing, but it provides certain standards for building infrastructure of astronomical data center. The astronomical databases help data mining and offer to users an easy access to observation metadata, images within celestial sphere and results of image processing. The astronomical web services (AWS) of UkrVO give to users handy tools for data selection from large astronomical catalogues for a relatively small region of interest in the sky. Examples of the AWS usage are showed.

    Behavioural properties are analyzed for web service contracts formulated in Business Process Execution Language (BPEL) and Choreography Description Language (CDL). The key result reported is an automated technique to check consistency between protocol aspects of the contracts. The contracts...... are abstracted to (timed) automata and from there a simulation is set up, which is checked using automated tools for analyzing networks of finite state processes. Here we use the Concurrency Work Bench. The proposed techniques are illustrated with a case study that include otherwise difficult to analyze fault...

  1. Building a biomedical ontology recommender web service.

    2010-06-22

    Researchers in biomedical informatics use ontologies and terminologies to annotate their data in order to facilitate data integration and translational discoveries. As the use of ontologies for annotation of biomedical datasets has risen, a common challenge is to identify ontologies that are best suited to annotating specific datasets. The number and variety of biomedical ontologies is large, and it is cumbersome for a researcher to figure out which ontology to use. We present the Biomedical Ontology Recommender web service. The system uses textual metadata or a set of keywords describing a domain of interest and suggests appropriate ontologies for annotating or representing the data. The service makes a decision based on three criteria. The first one is coverage, or the ontologies that provide most terms covering the input text. The second is connectivity, or the ontologies that are most often mapped to by other ontologies. The final criterion is size, or the number of concepts in the ontologies. The service scores the ontologies as a function of scores of the annotations created using the National Center for Biomedical Ontology (NCBO) Annotator web service. We used all the ontologies from the UMLS Metathesaurus and the NCBO BioPortal. We compare and contrast our Recommender by an exhaustive functional comparison to previously published efforts. We evaluate and discuss the results of several recommendation heuristics in the context of three real world use cases. The best recommendations heuristics, rated 'very relevant' by expert evaluators, are the ones based on coverage and connectivity criteria. The Recommender service (alpha version) is available to the community and is embedded into BioPortal.

    To solve the problem of the information share and services integration in population information system, we propose a multi-layer tree hierarchical architecture. The com mand (Web Service Call) is recursively multicast from top layer of tree to bottom layer of tree and statistical data are gathered from bottom layer to top layer. We implemented the architecture by using Web Services technology. In our implementation, client program is the requestor of Web Services,and all leaf nodes of the last layer are only the provider of Web Services. For those nodes of intermediate layers, every node is not only the provider of Web Services, but also the dispatcher of Web Services. We take population census as an example to describe the working flow of the architecture.

    2003-01-01

    In June 2000, the Biomedical Library at the University of South Alabama introduced Prospero, an electronic desktop document delivery service. From June 2000 to November 2002, Prospero delivered 28% of interlibrary loan requests and 72% of document delivery requests. In November 2002, the library conducted a user satisfaction survey of the Prospero service. Forty-two surveys were used. Fifteen responses were received from affiliated faculty, staff, and students, who generally expressed satisfaction with the service. Twenty-seven responses were received from unaffiliated users, comprised of medical libraries, individual users, and businesses. Based on the survey results, the library deemed the Prospero service a success. To better support users, the library's Web page was updated to include hardware and software requirements for successful use of the Prospero service, as well as screen shots of the Prospero process.

    2011-01-01

    Full Text Available Purpose: Providing services to library users with special needs makes libraries for the blind and partially sighted different from other types of libraries. In spite of the Slovenian Library Act which defines them as special libraries providing public library service,they have not become a part of the public library system yet. The national program for culture issued by the Ministry of Culture in 2008 stated that the solution should be proposed by the year 2011.Methodology/approach: The Centre for library system development at the National and University library made an analysis of the current state and identified the weaknesses of the Slovenian library system and services for the blind. The solutions and best practices from abroad, national legislation and professional guidelines for libraries serving the blind were also explored. The concept of providing library services to the blind as public services was elaborated.Results: The Centre for library system development suggested an integrated system with the central library providing library services i.e. reproduction of library materials in alternative techniques, and directing other libraries in providing services and developing new activities for the blind. Public libraries, already providing services to users with special needs should be encouraged to seek their own solutions.Originality/practical implications: The suggested concept of the national library for the blind is harmonized with the Slovenian library system and it could be realized with the cooperation of all the stakeholders involved.

    Frobert, L.; Kamb, L.; Trani, L.; Spinuso, A.; Bossu, R.; Van Eck, T.

    2011-12-01

    NERIES (2006-2010) was an Integrated Infrastructure Initiative (I3) project in the Sixth Framework Program (FP6) of the European Commission (EC), aiming at networking the European seismic networks, improving access to data, allowing access to specific seismic infrastructures and pursuing targeted research developing the next generation of tools for improved service and data analysis. During this project, a web portal was developed using web services to access data and a Visual Web Applications to display them. However these web services were not conform to any standard, making them difficult to consume by any new user interface. Therefore, for the NERA project, the follow-up of NERIES, we have proposed the use of web services standards to access our data. We have decided to use standards defined by the Open Geospatial Consortium (OGC). The OGC defines standards for the Web service interfaces to access geo-tagged data. The events and seismic stations are also geo-tagged making these web services suitable for our purpose. Using standard web services gives us the opportunity to distribute our data across all conformant consumers to these standards through various programming languages and applications We have implemented a preliminary version of web services conforming to the Web Map Service (WMS) and Web Feature Service (WFS) standard to access our catalog of seismic events (nearly 200 000 events). To visualize them we have made four examples demo on our web site using different technologies (Adobe Flash, JavaScript, Java with Nasa World Wind and UDig a desktop GIS application). In the future we hope to implement other OGC Web services standard like : - Sensor Observation Service (SOS) to provide seismic waveform records; - Web Notification Service (WNS); - Catalog Service for the Web (CSW) to provide a search engine of all our web services; - Web Processing Service (WPS) to process data between different services. The power of the use of OGC standards is the easy

    Composing existing web services for enterprise applications may enable higher level of reuse. However the composition processes are mostly static and lack of support for runtime redesign. In this paper, we describe our approach to the extension of the OWL-S ontology framework for dynamic web service composition. We raise the level of abstraction and propose an abstract service layer so that web services can be composed at the abstract service level instead of the concrete level. Each abstract service is attached with an instance pool including all instances of the abstract service to facilitate fail-over and dynamic compositions.

  1. A web services choreography scenario for interoperating bioinformatics applications

    Directory of Open Access Journals (Sweden)

    Cheung David W

    2004-03-01

    Full Text Available Abstract Background Very often genome-wide data analysis requires the interoperation of multiple databases and analytic tools. A large number of genome databases and bioinformatics applications are available through the web, but it is difficult to automate interoperation because: 1 the platforms on which the applications run are heterogeneous, 2 their web interface is not machine-friendly, 3 they use a non-standard format for data input and output, 4 they do not exploit standards to define application interface and message exchange, and 5 existing protocols for remote messaging are often not firewall-friendly. To overcome these issues, web services have emerged as a standard XML-based model for message exchange between heterogeneous applications. Web services engines have been developed to manage the configuration and execution of a web services workflow. Results To demonstrate the benefit of using web services over traditional web interfaces, we compare the two implementations of HAPI, a gene expression analysis utility developed by the University of California San Diego (UCSD that allows visual characterization of groups or clusters of genes based on the biomedical literature. This utility takes a set of microarray spot IDs as input and outputs a hierarchy of MeSH Keywords that correlates to the input and is grouped by Medical Subject Heading (MeSH category. While the HTML output is easy for humans to visualize, it is difficult for computer applications to interpret semantically. To facilitate the capability of machine processing, we have created a workflow of three web services that replicates the HAPI functionality. These web services use document-style messages, which means that messages are encoded in an XML-based format. We compared three approaches to the implementation of an XML-based workflow: a hard coded Java application, Collaxa BPEL Server and Taverna Workbench. The Java program functions as a web services engine and interoperates

  3. Using JavaScript and the FDSN web service to create an interactive earthquake information system

    Science.gov (United States)

    Fischer, Kasper D.

    2015-04-01

    The FDSN web service provides a web interface to access earthquake meta-data (e. g. event or station information) and waveform date over the internet. Requests are send to a server as URLs and the output is either XML or miniSEED. This makes it hard to read by humans but easy to process with different software. Different data centers are already supporting the FDSN web service, e. g. USGS, IRIS, ORFEUS. The FDSN web service is also part of the Seiscomp3 (http://www.seiscomp3.org) software. The Seismological Observatory of the Ruhr-University switched to Seiscomp3 as the standard software for the analysis of mining induced earthquakes at the beginning of 2014. This made it necessary to create a new web-based earthquake information service for the publication of results to the general public. This has be done by processing the output of a FDSN web service query by javascript running in a standard browser. The result is an interactive map presenting the observed events and further information of events and stations on a single web page as a table and on a map. In addition the user can download event information, waveform data and station data in different formats like miniSEED, quakeML or FDSNxml. The developed code and all used libraries are open source and freely available.

  4. Creating OGC Web Processing Service workflows using a web-based editor

    Science.gov (United States)

    de Jesus, J.; Walker, P.; Grant, M.

    2012-04-01

    The OGC WPS (Web Processing Service) specifies how geospatial algorithms may be accessed in an SOA (Service Oriented Architecture). Service providers can encode both simple and sophisticated algorithms as WPS processes and publish them as web services. These services are not only useful individually but may be built into complex processing chains (workflows) that can solve complex data analysis and/or scientific problems. The NETMAR project has extended the Web Processing Service (WPS) framework to provide transparent integration between it and the commonly used WSDL (Web Service Description Language) that describes the web services and its default SOAP (Simple Object Access Protocol) binding. The extensions allow WPS services to be orchestrated using commonly used tools (in this case Taverna Workbench, but BPEL based systems would also be an option). We have also developed a WebGUI service editor, based on HTML5 and the WireIt! Javascript API, that allows users to create these workflows using only a web browser. The editor is coded entirely in Javascript and performs all XSLT transformations needed to produce a Taverna compatible (T2FLOW) workflow description which can be exported and run on a local Taverna Workbench or uploaded to a web-based orchestration server and run there. Here we present the NETMAR WebGUI service chain editor and discuss the problems associated with the development of a WebGUI for scientific workflow editing; content transformation into the Taverna orchestration language (T2FLOW/SCUFL); final orchestration in the Taverna engine and how to deal with the large volumes of data being transferred between different WPS services (possibly running on different servers) during workflow orchestration. We will also demonstrate using the WebGUI for creating a simple workflow making use of published web processing services, showing how simple services may be chained together to produce outputs that would previously have required a GIS (Geographic

    2011-12-01

    The IRIS Data Management Center (DMC) has developed a suite of web services that provide access to the DMC's time series holdings, their related metadata and earthquake catalogs. In addition, services are available to perform simple, on-demand time series processing at the DMC prior to being shipped to the user. The primary goal is to provide programmatic access to data and processing services in a manner usable by and useful to the research community. The web services are relatively simple to understand and use and will form the foundation on which future DMC access tools will be built. Based on standard Web technologies they can be accessed programmatically with a wide range of programming languages (e.g. Perl, Python, Java), command line utilities such as wget and curl or with any web browser. We anticipate these services being used for everything from simple command line access, used in shell scripts and higher programming languages to being integrated within complex data processing software. In addition to improving access to our data by the seismological community the web services will also make our data more accessible to other disciplines. The web services available from the DMC include ws-bulkdataselect for the retrieval of large volumes of miniSEED data, ws-timeseries for the retrieval of individual segments of time series data in a variety of formats (miniSEED, SAC, ASCII, audio WAVE, and PNG plots) with optional signal processing, ws-station for station metadata in StationXML format, ws-resp for the retrieval of instrument response in RESP format, ws-sacpz for the retrieval of sensor response in the SAC poles and zeros convention and ws-event for the retrieval of earthquake catalogs. To make the services even easier to use, the DMC is developing a library that allows Java programmers to seamlessly retrieve and integrate DMC information into their own programs. The library will handle all aspects of dealing with the services and will parse the returned

  7. Persistence and availability of Web services in computational biology.

    Directory of Open Access Journals (Sweden)

    Sebastian J Schultheiss

    Full Text Available We have conducted a study on the long-term availability of bioinformatics Web services: an observation of 927 Web services published in the annual Nucleic Acids Research Web Server Issues between 2003 and 2009. We found that 72% of Web sites are still available at the published addresses, only 9% of services are completely unavailable. Older addresses often redirect to new pages. We checked the functionality of all available services: for 33%, we could not test functionality because there was no example data or a related problem; 13% were truly no longer working as expected; we could positively confirm functionality only for 45% of all services. Additionally, we conducted a survey among 872 Web Server Issue corresponding authors; 274 replied. 78% of all respondents indicate their services have been developed solely by students and researchers without a permanent position. Consequently, these services are in danger of falling into disrepair after the original developers move to another institution, and indeed, for 24% of services, there is no plan for maintenance, according to the respondents. We introduce a Web service quality scoring system that correlates with the number of citations: services with a high score are cited 1.8 times more often than low-scoring services. We have identified key characteristics that are predictive of a service's survival, providing reviewers, editors, and Web service developers with the means to assess or improve Web services. A Web service conforming to these criteria receives more citations and provides more reliable service for its users. The most effective way of ensuring continued access to a service is a persistent Web address, offered either by the publishing journal, or created on the authors' own initiative, for example at http://bioweb.me. The community would benefit the most from a policy requiring any source code needed to reproduce results to be deposited in a public repository.

  8. A New Approach to Development of Composite Web Services

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    With the requirement for complex Web Services steadily increasing, there is a growing interest for reusing basic, existing Web Services to composite new ones. We present a composite Web Services development approach driven by model driven architecture (MDA): using UML(Unified Modeling Language) class diagram to model structure PIM(Plateform Independent Platform) and UML activity diagram to model behavior PIM, then by model transformation converting the PIMs to specific Web Services specification platforms and execution platform to get the corresponding PSMs (platform specific models). The main contributions of this paper are the all-around solution to Web Services composition development and the transformation rules for structure and behavior model of Web Services between PIMs and PSMs.

    2013-03-01

    Full Text Available This article presents a model for creating a strong, user-centered web presence by pairing usability testing and the design process. Four rounds of usability testing were conducted throughout the process of building a new academic library web site. Participants were asked to perform tasks using a talk-aloud protocol. Tasks were based on guiding principles of web usability that served as a framework for the new site. Results from this study show that testing throughout the design process is an effective way to build a web site that not only reflects user needs and preferences, but can be easily changed as new resources and technologies emerge.

    2011-01-01

    Full Text Available Problem statement: With fast spreading of web services technology over the Internet, the quality aspects of a web service has received significant attention to the practitioners. The quality of web service includes both functional and nonfunctional details. In order to provide the correct and meaningful information to web service consumer, sometimes there is a need to compose existing web services in order to create new web service. Approach: We have proposed a Quality of Service (QoS broker based process model for Dynamic Web Service Composition (DWSC. The QoS broker in the proposed model is responsible for web service collection, selection, optimization and composition based on the service consumer’s requirements. It also verifies and certifies the functional and QoS specifications provided by service provider at the time of web service registration before publishing it in Universal Description, Discovery and Integration (UDDI registry. The detailed working of QoS broker is also presented in the study with functionality of each component. We will also discuss the process flowchart for new web service registration and web service composition at runtime. Results: The proposed QoS broker based model for dynamic web service composition solves the problems associated with quality of web service.

    Web-based workflow systems have gained considerable momentum in sequence-oriented bioinformatics. In structural bioinformatics, however, such systems are still relatively rare; while commercial stand-alone workflow applications are common in the pharmaceutical industry, academic researchers often still rely on command-line scripting to glue individual tools together. In this work, we address the problem of building a web-based system for workflows in structural bioinformatics. For the underlying molecular modelling engine, we opted for the BALL framework because of its extensive and well-tested functionality in the field of structural bioinformatics. The large number of molecular data structures and algorithms implemented in BALL allows for elegant and sophisticated development of new approaches in the field. We hence connected the versatile BALL library and its visualization and editing front end BALLView with the Galaxy workflow framework. The result, which we call ballaxy, enables the user to simply and intuitively create sophisticated pipelines for applications in structure-based computational biology, integrated into a standard tool for molecular modelling.  ballaxy consists of three parts: some minor modifications to the Galaxy system, a collection of tools and an integration into the BALL framework and the BALLView application for molecular modelling. Modifications to Galaxy will be submitted to the Galaxy project, and the BALL and BALLView integrations will be integrated in the next major BALL release. After acceptance of the modifications into the Galaxy project, we will publish all ballaxy tools via the Galaxy toolshed. In the meantime, all three components are available from http://www.ball-project.org/ballaxy. Also, docker images for ballaxy are available at https://registry.hub.docker.com/u/anhi/ballaxy/dockerfile/. ballaxy is licensed under the terms of the GPL. © The Author 2014.

    Taylor, M.; Platon, R.; Chipperfield, A.; Draper, P.; McIlwrath, B.; Giaretta, D.

    Web Services are gaining great popularity in the Grid community, and with good reason. The Starlink project is adopting Web Services as the method of interapplication communication. This is being done natively in new Java-based applications while older applications are being wrapped to provide Web Service interfaces. We are in this way providing interoperability between the generations of software in a heterogeneous, distributed manner and allowing the software to be usable in a distributed environment such as the GRID.

  16. A web service for service composition to aid geospatial modelers

    2012-04-01

    The identification of appropriate mechanisms for process reuse, chaining and composition is considered a key enabler for the effective uptake of a global Earth Observation infrastructure, currently pursued by the international geospatial research community. In the Earth and Space Sciences, such a facility could primarily enable integrated and interoperable modeling, for what several approaches have been proposed and developed, over the last years. In fact, GEOSS is specifically tasked with the development of the so-called "Model Web". At increasing levels of abstraction and generalization, the initial stove-pipe software tools have evolved to community-wide modeling frameworks, to Component-Based Architecture solution, and, more recently, started to embrace Service-Oriented Architectures technologies, such as the OGC WPS specification and the WS-* stack of W3C standards for service composition. However, so far, the level of abstraction seems too low for implementing the Model Web vision, and far too complex technological aspects must still be addressed by both providers and users, resulting in limited usability and, eventually, difficult uptake. As by the recent ICT trend of resource virtualization, it has been suggested that users in need of a particular processing capability, required by a given modeling workflow, may benefit from outsourcing the composition activities into an external first-class service, according to the Composition as a Service (CaaS) approach. A CaaS system provides the necessary interoperability service framework for adaptation, reuse and complementation of existing processing resources (including models and geospatial services in general) in the form of executable workflows. This work introduces the architecture of a CaaS system, as a distributed information system for creating, validating, editing, storing, publishing, and executing geospatial workflows. This way, the users can be freed from the need of a composition infrastructure and

    Full Text Available Cloud Computing is a paradigm shift in the field of Computing. It is moving at an incredible fast pace and one of the fastest evolving domains of computer science today. It consist set of technology and service models that concentrates on the internet base use and delivery of IT applications, processing capability, storage and memory space. There is a shift from the traditional in-house servers and applications to the next generation of cloud computing applications. With many of the computer giants like Google, Microsoft, etc. entering into the cloud computing arena, there will be thousands of applications running on the cloud. There are several cloud environments available in the market today which support a huge consumer-base. Eventually this will lead to a multitude of standards, technologies and products being provided on the cloud. Consumers will need certain degrees of flexibility to use the cloud application/services of their choice and at the same time will need these applications/services to communicate with each other. This paper emphasizes cloud computing and provides a solution to achieve Interoperability, which is in the form of Web Services. The paper will also provide a Live Case Study where interoperability comes into play - Connecting Google App Engine and Microsoft Windows Azure Platform, two of the leading Cloud Platforms available today. GAE and WAP are two Cloud Frameworks which have very little in common, making interoperability an absolute necessary.

    Based on the analysis of research status of domestic and international GIS web service aggregation and development tendency of public platform of GIS web service, the paper designed software architecture of GIS web service aggregation based on GIS web service group. Firstly, using heterogeneous GIS services model, the software architecture converted a variety of heterogeneous services to a unified interface of GIS services, and divided different types of GIS services into different service groups referring to description of GIS services. Secondly, a service aggregation process model was designed. This model completed the task of specific service aggregation instance, by automatically selecting member GIS Web services in the same service group. Dynamic capabilities and automatic adaptation of GIS Web services aggregation process were achieved. Thirdly, this paper designed a service evaluation model of GIS web service aggregation based on service group from three aspects, i.e. GIS Web Service itself, networking conditions and service consumer. This model implemented effective quality evaluation and performance monitoring of GIS web service aggregation. It could be used to guide the execution, monitor and service selection of aggregation process. Therefore, robustness of aggregated GIS web service was improved. Finally, the software architecture has been widely used in public platform of GIS web service and a number of geo-spatial framework constructions for digital city in Sichuan Province, and aggregated various GIS web services such as World Map(National Public Platform of Geo-spatial Service), ArcGIS, SuperMap, MapGIS, NewMap etc. Applications of items showed that this software architecture was practicability.

    2012-02-01

    Full Text Available Web service technology provides basic infrastructure for deploying collaborative business processes. Web Service security standards and protocols aim to provide secure communication and conversation between service providers and consumers. Still, for a client calling a Web service it is difficult to ascertain that a particular service instance satisfies—at execution time—specific non-functional properties. In this paper we introduce the notion of certified Web service assurance, characterizing how service consumers can specify the set of security properties that a service should satisfy. Also, we illustrate a mechanism to re-check non-functional properties when the execution context changes. To this end, we introduce the concept of context-aware certificate, and describe a dynamic, context-aware service discovery environment.

    2011-06-01

    Full Text Available Abstract Background Many bioinformatics algorithms and data sets are deployed using web services so that the results can be explored via the Internet and easily integrated into other tools and services. These services often include data from other sites that is accessed either dynamically or through file downloads. Developers of these services face several problems because of the dynamic nature of the information from the upstream services. Many publicly available repositories of bioinformatics data frequently update their information. When such an update occurs, the developers of the downstream service may also need to update. For file downloads, this process is typically performed manually followed by web service restart. Requests for information obtained by dynamic access of upstream sources is sometimes subject to rate restrictions. Findings SideCache provides a framework for deploying web services that integrate information extracted from other databases and from web sources that are periodically updated. This situation occurs frequently in biotechnology where new information is being continuously generated and the latest information is important. SideCache provides several types of services including proxy access and rate control, local caching, and automatic web service updating. Conclusions We have used the SideCache framework to automate the deployment and updating of a number of bioinformatics web services and tools that extract information from remote primary sources such as NCBI, NCIBI, and Ensembl. The SideCache framework also has been used to share research results through the use of a SideCache derived web service.

    Directory of Open Access Journals (Sweden)

    Dmitry Repchevsky

    Full Text Available Despite of the variety of available Web services registries specially aimed at Life Sciences, their scope is usually restricted to a limited set of well-defined types of services. While dedicated registries are generally tied to a particular format, general-purpose ones are more adherent to standards and usually rely on Web Service Definition Language (WSDL. Although WSDL is quite flexible to support common Web services types, its lack of semantic expressiveness led to various initiatives to describe Web services via ontology languages. Nevertheless, WSDL 2.0 descriptions gained a standard representation based on Web Ontology Language (OWL. BioSWR is a novel Web services registry that provides standard Resource Description Framework (RDF based Web services descriptions along with the traditional WSDL based ones. The registry provides Web-based interface for Web services registration, querying and annotation, and is also accessible programmatically via Representational State Transfer (REST API or using a SPARQL Protocol and RDF Query Language. BioSWR server is located at http://inb.bsc.es/BioSWR/and its code is available at https://sourceforge.net/projects/bioswr/under the LGPL license.

    2005-01-01

    Tests involving a large number of test cases and test scenarios are always time- and effort-intensive, and use ad hoc approaches. Test management is needed to control the complexity and the quality of the testing of large software systems. The reporting mechanism is critical for monitoring the testing progress, analyzing test results, and evaluating the test effectiveness for a disciplined testing process throughout the testing lifecycle. This paper presents an XML-based report generation method for large system testing. The service-oriented architecture enables flexible test report generation, presentation, and exchange to facilitate collaboration in a distributed environment. The results show that proper reporting can effectively improve the visibility of the testing process and that this web-based approach is critical to enhance communication among multiple testing groups.

    2013-01-01

    Existing Web service selection approaches usually assume that preferences of users have been provided in a quantitative form by users.However,due to the subjectivity and vagueness of preferences,it may be impractical for users to specify quantitative and exact preferences.Moreover,due to that Quality of Service (QoS) attributes are often interrelated,existing Web service selection approaches which employ weighted summation of QoS attribute values to compute the overall QoS of Web services may produce inaccurate results,since they do not take correlations among QoS attributes into account.To resolve these problems,a Web service selection framework considering user's preference priority is proposed,which incorporates a searching mechanism with QoS range setting to identify services satisfying the user's QoS constraints.With the identified service candidates,based on the idea of Principal Component Analysis (PCA),an algorithm of Web service selection named PCAoWSS (Web Service Selection based on PCA) is proposed,which can eliminate the correlations among QoS attributes and compute the overall QoS of Web services accurately.After computing the overall QoS for each service,the algorithm ranks the Web service candidates based on their overall QoS and recommends services with top QoS values to users.Finally,the effectiveness and feasibility of our approach are validated by experiments,i.e.the selected Web service by our approach is given high average evaluation than other ones by users and the time cost of PCA-WSS algorithm is not affected acutely by the number of service candidates.

    Granell, Carlos; Tamayo, Alain; Huerta, Joaquín

    2012-01-01

    Recent distributed computing trends advocate the use of Representational State Transfer (REST), which aligns to the same principles than shape the Web, to alleviate the inherent complexity of the Web services standards in building service-oriented web applications. In this paper, we focus on the particular case of geospatial services interfaced by the OGC Web Processing Service (WPS) specification, geoprocessing services on top of service oriented architectures, in order to assess whether WPS-based geoprocessing services can be viewed from the architectural principles exposed in REST. Our concluding remarks suggest that the adoption of REST principles, to specially harness the built-in mechanisms of the HTTP application protocol, may be beneficial in scenarios where ad hoc composition of geoprocessing services are required, common for most non-expert users of geospatial information infrastructures.

    Healthcare digital libraries (DLs) increasingly make use of dedicated services to access functionality and/or data. Semantic (web) services enhance single services and facilitate compound services, thereby supporting advanced applications on top of a DL. The traditional process management approach tends to focus on process definition at build time rather than on actual service events in run time, and to anticipate failures in order to define appropriate strategies. This paper presents a novel approach where service coordination is distributed among a set of agents. A dedicated component plans compound semantic services on demand for a particular application. In failure, the planner is reinvoked to define contin- gency strategies. Finally, matchmaking is effected at runtime by choosing the appropriate service provider. These combined technologies will provide key support for highly flexible next-generation DL applications. Such technologies are under development within CASCOM.

    Full Text Available Web Service is an emerging technology for the agricultural field to improve crop productivity in aspect of quality and quantity. India is known as an agricultural country and majority of Indian population lives in rural areas. The Indian Farmers are facing a lot of difficulties to increase production of crops. Now a day lots ofresearch has been done in this area, but still farmers are unable to achieve upper-bound yield due to lack of knowledge about this research. So to overcome this problem we are proposing a novel framework that is “Krishi-Services” to make various services and information available at their door steps. For the development of country and the betterment of rural people in the remote area, we are using information technology to collect information from various online sources and thereby making farmers aware of recent technologies.

  12. Integration of Library Services with Internet of Things Technologies

    Full Text Available The SELIDA framework is an integration layer of standardized services that takes an Internet-of-Things approach for item traceability in the library setting. The aim of the framework is to provide tracing of RFID tagged physical items among or within various libraries. Using SELIDA we are able to integrate typical library services—such as checking in or out items at different libraries with different Integrated Library Systems—without requiring substantial changes, code-wise, in their structural parts. To do so, we employ the Object Naming Service mechanism that allows us to retrieve and process information from the Electronic Product Code of an item and its associated services through the use of distributed mapping servers. We present two use case scenarios involving the Koha open source ILS and we briefly discuss the potential of this framework in supporting bibliographic Linked Data.

    In today's businesses, service-oriented architectures represent the main paradigm for IT infrastructures. Indeed, the emergence of Internet made it possible to set up an exploitable environment to distribute applications on a large scale, and this, by adapting the notion of "service". With the integration of this paradigm in Business to Business Domain (B2B), the number of web services becomes very significant. Due to this increase, the discovery and selection of web services meeting customer...
