Providing Global Access to World Science: Overcoming
Standards Challenges Through Federated Search
CODATA 2008, Kyiv, Ukraine
Thomas F. Lahr US Geological Survey
Reston, VA USA
Co-Chair, US Science.gov Alliance
Alternate US Representative, WorldWideScience.org Alliance
Slide 2: Why WorldWideScience.org?
There is a need to find national scientific and technical information quickly and easily, but information is dispersed across thousands of web sites ("Surface Web") in addition to being found within databases or portals ("Deep Web").
Slide 3: Surface Web vs Deep Web 2005
Size: Estimated to be 8+ billion (Google) to 45 billion (About.com) web pages
Static, crawlable web pages
Large amounts of unfiltered information
Limited to what is easily found by search engines
Size: Estimated to be 5 to 500 times larger (BrightPlanet)
Dynamically generated content that lives inside databases
High-quality, managed, subject-specific content
Growing faster than surface web (BrightPlanet)
Slide 4: National Science Portals Collaboration and Coordination
2004 Vascoda (Germany) and Science.gov (US) and KISTI (Korea) Discussions and Meetings
2005 and 2006 IFLA Norway Korea – Ad Hoc Meetings of National Science Portals (hosted by GIOPS)
June 2006 ICSTI Meeting Washington DC
Frierson - "National Science Portals: New Potential Partnerships for Global Discovery"
Warnick - "Science.world" Portal
ICSTI Science Portals Forum Proposed
Slide 5: ICSTI Science Portals Forum Proposal
Organize and host 2 meetings
Create a summary matrix comparing national and international science portals to identify key characteristics and issues
Mobilize a proof of concept trial for a "cross science" portals search
Develop a plan of action
ICSTI Immediately funded 1 and 2
Slide 6: 1. Organize and host 2 meetings
January 2007 - ICSTI winter meeting in London
June 2007 - ICSTI meeting Nancy
Slide 7: 2. Create a summary matrix comparing national and international
science portals to identify key characteristics and issues
What is a portal?
How to define scope and coverage
Intellectual property rights management
Search techniques- browse taxonomies, site searching, deep web, metadata, data, publications Languages
Slide 8: US DOE/BL Agreement
In January 2007 the US Department of Energy and the British Library agreed to partner to develop a global science gateway to accelerate scientific discovery
Slide 9:
WorldWideScience.org
June 2007 demonstration
12 databases/10 countries
Invited others to join in developing governance documents-Feb 2008
Slide 10: How Does the WorldWide Science Gateway work?
The approach is to capitalize on existing "federated search" technology to search collections of science information distributed across the globe.
This enables much-needed access to both prominent as well as smaller, less well-known sources of highly valuable science.
Users simply submit a single query into the WorldWideScience.org search engine to launch simultaneous searching of the databases and portals of participating nations.
Results are returned in relevance-ranked order.
