Global Search and Distributed Repositories: Science.World

Slide01

Walter Warnick, Director
Office of Scientific and Technical Information (OSTI)
U.S. Department of Energy (DOE)

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

Slide02

Accelerating science knowledge diffusion accelerates science progress

Slide03

Science depends on the diffusion of knowledge

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."

Slide04

Sequential diffusion is too slow!

"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

Slide05

Often the knowledge scientists need resides in distant communities

Acoustics
Agricultural Engineering
Astrodynamics
Bioinformatics
Condensed Matter Physics
Cognitive Neuroscience
Cosmology
Cryogenics
Cybernetics
Geology
Genomics
Immunology
Limnology
Materials Science
Meteorology
Nanoscience
Oceanography
Plasma Physics
Radiology
Seismology
Spectroscopy
Stereochemistry

Slide06

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

Slide07

Got documents? Need discovery?

Slide08

No time for "door-to-door" searching

Slide09

Current early models for global discovery

Science.gov

E-print Network

Science Conferences

Slide10

Deep Web

Current models include only a few international sources
Only small parts of the deep Web are metasearchable

Slide11

Energy Technology Data Exchange

Slide12

Current ETDE Member Countries

Brazil
Canada
Denmark
Finland
France
Germany
Korea, Republic of
Mexico
The Netherlands
Norway
Portugal
Spain
Sweden
Switzerland
United Kingdom
United States

Slide13

ETDE's Distributed Searching Strategy

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

Slide14

Example of International Federated Searching

Slide15

"Distributed Search Results"

Slide16

Distributed Search Results (cont.)

Slide17

"Distributed Search Results, Documents from ETDEWEB"

Slide18

Distributed Search Results, Documents from CORDIS
Information Service and IEA Energy Information Centre

Slide19

"Distributed Search Results, Documents from the Science.gov Web site"

Slide20

Distributed Search Results, Documents from Nordic Energy Index and the Danish Energy R&D Projects

Slide21

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)

Slide22

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.
