International Council for Scientific and Technical Information (ICSTI) [exit federal site] Public Conference:

PARTNERING IN SCIENCE INFORMATION: NECESSITIES OF CHANGE

Lister Hill Center Auditorium at the National Library of Medicine
Bethesda, Maryland
7–8 June 2006 (Slide 1)

Accelerating science knowledge diffusion accelerates science progress. Link to larger image.

Slide 2: Accelerating science knowledge diffusion accelerates science progress


Slide 3: Science depends on the diffusion of knowledge

Science depends on the diffusion of knowledge. Link to larger image.

Isaac Newton expressed this thought most eloquently in 1676, when he wrote:

"If I have seen further than others, it is by standing on the shoulders of giants."

"The calculus of innovation is really quite simple:

  • Knowledge drives innovation;
  • Innovation drives productivity;
  • Productivity drives our economic growth.

That's all there is to it."

– William R. Brody
President, The Johns Hopkins University
Member, Council on Competitiveness
U.S. Competitiveness: The Innovation Challenge
Testimony to the House Committee on Science
July 21, 2005

Slide 6: The Deep Web Is HUGE!

  • 99% of scientific documents in databases in Deep Web
  • Deep Web is not accessible to search engines and robots
Challenge: Metasearch has scaling issues

ETDE's Distributed Searching Strategy

  • ETDEWEB's new distributed search feature makes R&D information from 39 databases and more than 1,800 Websites available with one search
  • Science.gov
  • Science Conferences

Overcoming Challenges. Link to larger image.

Slide 21: Overcoming Challenges

  • Scalability
  • Different languages
  • Ongoing viability of the deep Web resources themselves (managing the perception that Science.world eliminates the need to maintain individual deep Web databases)
  • Including "user authenticated" systems (which, in many cases, are some of the best)

Conclusion. Link to larger image.

Slide 22: Conclusion

The U.S. Department of Energy is a willing collaborator in pursuing the vision of Science.world.

We welcome other interested parties to begin a dialogue and a plan of action for making this vision a reality.
