Slide 2: Why

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

Surface Web vs Deep Web 2005.  Link to larger image.
  • Size: Estimated to be 8+ billion (Google) to 45 billion ( 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)

  1. Organize and host 2 meetings
  2. Create a summary matrix comparing national and international science portals to identify key characteristics and issues
  3. Mobilize a proof of concept trial for a "cross science" portals search
  4. Develop a plan of action

ICSTI Immediately funded 1 and 2

  • 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

US DOE/BL Agreement.  Link to larger image.

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

  • Invited others to join in developing governance documents-Feb 2008

Slide 10: How Does the WorldWide Science Gateway work?

How Does the WorldWide Science Gateway work? Link to larger image.

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 search engine to launch simultaneous searching of the databases and portals of participating nations.

Results are returned in relevance-ranked order.
