1. July, 04 What is the Semantic Web? (A mostly pictorial tour) Prof. James Hendler Hendler@cs.umd.edu http://www.cs.umd.edu/~hendler http://www.mindswap.org Presentations, Downloads and Demos:

2. July, 04 Information Convergence Convergence not just in devices, also in “information” Your personal information (phone, PDA,…) Calendar, photo, home page, files… Your “professional” life (laptop, desktop, … Grid) Web site, publications, files, databases, … Your “community” contexts (Web) Hobbies, blogs, fanfic, social networks… The Web teaches us that people will work to share How do we CREATE, SEARCH, and BROWSE in the non-text based parts of our lives?

3. July, 04 Getting there: Make Web content more “machine-readable!” Lassila et al, 2002

4. July, 04 The Semantic Wave (Berners-Lee, 03) YOU ARE HERE

5. July, 04 Now. RDF, RDFS and OWL are ready for prime time Designs are stable, implementations maturing Major Research investment translating into application development and commercial spinoffs Adobe 6.0 embraces RDF IBM releases tools, data and partnering HP extending Jena to OWL Tucana announces results for 1B triple queries Proprietary OWL ontologies for vertical markets c.f. pharmacology, HMO/health care,... Soft drinks Several new starts in SW space

6. July, 04 Now: huge potential Data integration identified as $100Bs world-wide market with significant govt interest creating a user-pull Ontology development efforts, in OWL, aimed at information mgt ongoing in US govt include –NIST, NLM, EPA, DHS, DoD, DOJ, FDA, NIH, USGS, NOAA Huge potential follow-on market - EAI for the small business making external data and info resources integrable Could do for integration what Visicalc (excel) did for report generation

7. July, 04 Now: Tools for tool builders Like the pre-MOSAIC WWW… …but, it is much easier to get started than it was even a year ago, Parsers, APIs, triple-stores http://www.daml.org/tools http://www.w3.org/RDF End to end no longer takes a “miracle” Prototype OWL website took three undergraduates about 1 month. End user tools just starting to emerge “Metaphors” growing

19. July, 04 Social networks: e.g. Friend of a Friend (FOAF) Say stuff about yourself (or others) in OWL files, link to who you “know” Jim Hendler Dr Jim Hendler be972c7a602683f7cf3c7a1fd0949c565debe4d3 http://www.cs.umd.edu/~jen/foaf.rdf Estimates of the number of Foaf users range from 2M-5M

31. July, 04 Longer term?: Adding Proof

32. July, 04 The “Policy Aware Web”

33. July, 04 Conclusion The Semantic Web is here The question isn’t if, but “how much” Semantic Web technologies have a promising future and an exciting potential The business case is emerging Enterprise integration on the Web Database, image, and services as 1st class Web citizens Portal technology “in the small” The future feed is exciting Rules and Proof -> “Policy Aware” Web
