1. Revolutionary System Models, The Net, & The Public Interest The Interspace Prototype (1997-2000) Digital Libraries Initiative (1994-1998) Worm Community System (1990-1993) Telesophy System (1984-1989) www.canis.uiuc.edu

2. Revolutionary System Models, The Net, & The Public Interest Bruce Schatz Digital Library Research Program and NCSA University of Illinois at Urbana-Champaign schatz@uiuc.edu, http://canis.uiuc.edu NRC CSTB Workshop on Advancing the Public Interest through Knowledge and Distributed Intelligence National Academy of Sciences, September 25, 1997

3. Revolutionary System Models Where do new Systems come from? –Systems projects can Build Models –Models can inspire Mass Infrastructure Sponsor determines Purpose of Systems –Public Interest is not Commercial –Revolutionary Systems is not Commercial NSF technology + Foundation sponsorship can build revolutionary system models!

4. 1965 1975 1985 1995 2000 2010 ARPANETInternet Interspace The Third Wave of Net Evolution PROTOCOLSIPFTP HTTP CORBACP SERVICES Distributed Files Global Hypermedia Distributed Objects Global Semantics FUNCTIONAccessOrganization Analysis UNITSPacketsFilesLinksObjectsConcepts Distributed Paths Categories SMP

5. Evolution of the Net The Present: Access –The Net fetches documents The Future: Organization –The Net searches repositories The Millennium: Analysis –The Net correlates information From the Internet (data transmission) to the Interspace (information manipulation)

6. System Model Timeline 1984 Telesophy proposed at Bellcore – revolutionary system prototype developed 1989 Schatz systems advisor at NCSA –20th Anniversary ARPANET Symposium 1994 NCSA Mosaic gains many users –Mosaic 1M, Netscape 50M, Explorer 100M 1999 Web achieves Telesophy functionality –browsing & sharing multimedia documents

8. Advancing the Public Interest Industrial R&D labs have Vanished Commercial pressures push Advertising Where are Revolutionary Models today? At Universities, with public & private funds For example...

9. Global Cultural Memory Enable Everyone to understand –How They Have Lived and –How They Will Live The Structures of Everyday Life –recorded over space and time –correlated in a global information space Appreciate the Past and Predict the Future

10. Evolutionary System Model Getty project using commercial technology Museum-style Web collection curators to classify from big sources Champaign County Historical information county-level community repository 5000 Historical Societies in US

15. Revolutionary System Model A planet for every kid’s local environment Federating the planets into a universe Ordering all planets from kid’s POV Flying through the Kids Universe Finding similar kids from different POVs Connecting historically through museums this is feasible due to NSF technology!!

20. Research Issues in KDI Community Repositories [sovereign individual] –indexing all the knowledge of small groups Semantic Federation [transient centralization] –creating virtual libraries from distributed repositories Information Analysis [think globally, act locally] –correlating across repositories to solve problems The World of a Billion Repositories: The Interspace of the 21st Century http://www.canis.uiuc.edu/keytalks.html

21. Community System browse and share all the knowledge of a community data results (database management)(electronic mail) literature news (information retrieval) (bulletin boards ) knowledge (hypertext annotations) Formal Informal

22. Worm Community System WCS Information: Literature Biosis, Medline, newsletter, meetings Data Genes, Maps, Sequences, strains, people WCS Functionality Browsingsearch, navigation Filteringselection, analysis Sharinglinking, publishing WCS: 250 users at 50 labs across the Internet

29. Federation Techniques Structure Federation using SGML Syntactic Federation using multiple views Semantic Federation using term suggestion examples from DLI Testbed http://dli.grainger.uiuc.edu

35. Analysis Enviroments Concept Spaces for interactive suggestion Category Maps for semantic clustering Information Spaceflight for navigation examples from DLI Research http://canis.uiuc.edu/interspace/

43. Interspace Prototype semantic retrieval concept spaces semantic interoperability vocabulary switching semantic indexing object categorization semantic clustering category maps information spaceflight region visualization analysis environment path correlations

44. KDI Implications Sovereign Individual –community repositories for custom indexing Transient Centralization –community curators as relationship bonders Think Globally, Act Locally –vocabulary switches for correlation infrastructure Situational Analysis –dynamic categorization for problem solving Zen of the Net –at one with the knowledge of the world (mushin)
