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!

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)

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

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...

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

Evolutionary System Model
• Getty project using commercial technology
• Museum-style Web collection

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!!

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

Federation Techniques
• Structure Federation using SGML
• Syntactic Federation using multiple views
• Semantic Federation using term suggestion
• examples from DLI Testbed

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

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)
