4. The Semantic Web “The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” • Goal: Evolve the Web – • From sites designed for human consumption • To sites also understandable and usable by computer programs • What would that do for us? • Query answering rather than document retrieval • Services findable, usable, and composable by automated agents • Information exchange among independently designed programs • How are we getting there from here? • For documents – • Structure, ala XML • Ontologies to provide intended meaning of terms • For services – Computer interpretable descriptions

5. KD-D Project Objectives • Tools for authoring analysis reports as hyperwebs of Semantic Web documents • Automated services supporting analysis reports

6. Authoring Tools • Develop tools for authoring analysis reports as hyperwebs of Semantic Web documents • Tools to build knowledge base of supporting data and results • Tools to produce report as text version of knowledge base content • Develop automated services supporting analysis reports • Report templates that specify – • Syntactic structure of the document • Ontologies describing the meaning of the vocabulary used in the template • Sequence of entities (class instances) that the document will describe • Perspective for each entity description • Semantic search tools for effectively finding data relevant to a task • Interactive extraction tools for documents and typed text • Knowledge structuring and editing tools • Linking of analysis results to supporting data

7. Services Supporting Analysis Results • Develop tools for authoring analysis reports as hyperwebs of Semantic Web documents • Develop automated services supporting analysis reports • Monitor for changes in data supporting results Changes and updates to data reflected in reported results • Check results for incongruities with data and other results • Include query-answering agent with report • Integrate results from multiple authors using differing vocabularies

12. Kinds of Situations Templates for more specific situations 12 Knowledge Systems Laboratory, Stanford University

13. Election Analysis Template The more specific Election template 13 Knowledge Systems Laboratory, Stanford University

14. Search for documents about president Search for reference documents containing “president” 14 Knowledge Systems Laboratory, Stanford University

15. News Stories About President Two documents found Only current news stories about an election were considered 15 Knowledge Systems Laboratory, Stanford University

16. Found Documents Added To Template Description Entering a candidate Found documents entered into description 16 Knowledge Systems Laboratory, Stanford University

17. No Matches For Zivojinovic No politician named Zivojinovic was found in the knowledge base 17 Knowledge Systems Laboratory, Stanford University

18. Zivojinovic is a Movie Star System knows about a Movie Star named Zivojinovic 18 Knowledge Systems Laboratory, Stanford University

19. Zivojinovic is a Candidate Analyst says the Movie Star is a candidate Analyst can extend the template 19 Knowledge Systems Laboratory, Stanford University

20. Located In is a Property “located in” is a property in the knowledge base 20 Knowledge Systems Laboratory, Stanford University

21. Located In Yugoslavia Analyst enters “yugoslavia” as the location of the election 21 Knowledge Systems Laboratory, Stanford University

22. Description of Yugoslavia System recognizes “yugoslavia” as a known country 22 Knowledge Systems Laboratory, Stanford University

23. Located in Entity Yugoslavia System changes the location to the Yugoslavia knowledge base entity 23 Knowledge Systems Laboratory, Stanford University

24. Filled Out Template Completed template description of the election 24 Knowledge Systems Laboratory, Stanford University
