Background

• Who Are We? – BBN – Long-term Sherpa of the Semantic Web and other cool stuff

• Goals for Today– Discuss the opportunity to expand the Semantic Web

through Web 2.0– Some observations, insights, and possible directions

• Agenda– Web 2.0 Fly By– Semantic Web Opportunity– Semantic 2.0 Sauce– Semantic Web 2.0 Demonstration– Summary

Web 2.0 Fly ByWeb 2.0 is really an “after-the-fact” catch-all for a collectively

recognized phenomena

What does it all mean?

•Plays Nice with Others– Reinforcing and enhancing

•Network Assumed (Duh!)•Small, Simple, and Easy

– Do one small thing well - think UNIX shell scripts

– Not monolithic and comprehensive rather contributing

•Flexible Distribution– Processing, GUI, etc

– Optimizes resources, locality

– Easy Integration, Scripting, and Interfacing

•Mere Use often Produces Enrichment and Scale

– Participatory

– Forms Collective Intelligence/Enrichment

•A Better View into the Real Treasure - Data

And we are only getting started…

Clearly, Data is the fuel of Web 2.0

• “Data is the Next Intel Inside”• For the most part still remains imprisoned• Tough, Rewarding Data Challenges Ahead…

– Privacy– Control and Ownership– Distribution– Security/Trust– Digital Rights Management (DRM) (Yuk!)– Access– Integration

• "embraced and extended" their data suppliers • The race is on to own certain classes of core data • Free vs. Proprietary• (Oh, data has only begun to explode)

– Web 2.0 feeds the fire along with other catalysts

Semantic Web ContributionsYes, we can do that…

Data and Service Integration• Merge/Align• Deconfliction• Consistency• Trust• Re-Mixable

Policy• Security• Privacy• Distribution

Data and Service Transformation• Semantics• Tagging• Technical

Access• Query• Search

Logic• Discovery• Inference

Adding Semantic Sauce to Web 2.0

• Three Steps1. Recognize and Leverage Foundation

2. Collect and Corral Best Practices

3. Offer Services

Recognize and Leverage Foundation

A lot of solid progress…

• Standards– RDF, OWL, SPARQL, SWRL, …

• Platforms– Jena, Sesame, …

• Tools– Protégé, SWeDE

• Practices– SWBPD

Collect and Corral Best Practices

• Help with Transition

• Direction and Measurement

Offer Services

• Supporting Semantic Services– Internal enrichment to existing Web 2.0– Trust, Security, Segmented Distribution, Integration,…– Often subsets of existing Semantic Web applications

• Full Semantic Services– Adds to the diverse Web 2.0 palette– Semantic Themes (email, searching, organization, …)

• Semantic Scripting and Automation– Take tagging to the next level– Reduce/isolate low level complexity
