Interest
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

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

•
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

The Interspace of the 21st Century

Community System
results
data
(database management)
(electronic mail)
knowledge
(hypertext annotations)
literature
(information retrieval)
Formal
news
(bulletin boards)
Informal
browse and share all the knowledge of a community
Worm Community System
• WCS Information:
Literature Biosis, Medline, newsletter, meetings
Data
Genes, Maps, Sequences, strains, people
• WCS Functionality
Browsing
search, navigation
Filtering
selection, analysis
Sharing
linking, publishing
WCS: 250 users at 50 labs across the Internet
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
Analysis Enviroments
• Concept Spaces for interactive suggestion
• Category Maps for semantic clustering
• Information Spaceflight for navigation
• examples from DLI Research

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)
