Semantic Web Tools for Authoring and Using Analysis Results Richard Fikes Robert McCool Deborah McGuinness Sheila McIlraith Knowledge Systems Laboratory Stanford University

Knowledge Systems Laboratory, Stanford University4 The Semantic Web  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 “ “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.”

Knowledge Systems Laboratory, Stanford University5 KD-D Project Objectives  Tools for authoring analysis reports as hyperwebs of Semantic Web documents  Automated services supporting analysis reports

Knowledge Systems Laboratory, Stanford University6 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

Knowledge Systems Laboratory, Stanford University7 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
