Sorry for the late contribution – I was offline when this was officially due. These are a few use case interests from my research interests and also from consulting. References point to some examples of work I or colleagues have done in these areas. The last point is work led by McIlraith in our group at Stanford. - search – from simple things like structured search like retrieving tech reports, calendar entries[0], etc. The search should include both free text search and utilizing markup information and ontology definitions. This moves into conceptual search. An early example of simple and more complicated conceptual search using ontologies, markup, and free text search is FindUR [1-3] - intelligent interoperable e-commerce. Use ontologies for all levels of support including simple things like integrity checks, more complicated support such as ontology merging and mapping to “standard” upper level ontologies such as UNSPSC, etc. Simple early versions of this include electronic yellow pages such as Directory Westfield. More complicated versions of this include real configuration and solutions across complicated domains. Early examples of ontology-enhanced configuration includes work on PROSE/QUESTAR [5]. - Explainable query answering systems using background ontologies and markup to both answer queries as well as to provide followup questions. One way of visualizing this might be “ask jeeves done with knowledge representation” (instead of through a lot of hard coding). - Personalized assistant. One example I like is an assistant supporting the logistics of travel – both making travel reservations and also integrating that into appropriate systems like my palm pilot, expense forms, etc. I have a bit of this in a presentation for ICC2001 (but Mike Dean’s detailed example is another excellent example of this issue). - Web services. One of the focuses of KSL, Stanford's research over the last 1.5 years has been the confluence of the Semantic Web and Web Services -- self-contained Web-accessible programs, and devices, together with distributed computing architectures. As with DAML+OIL (in the guise of DAML-S), we would like to use WOL to create ontologies of Web Service properties and capabilities. Such annotations would be used to automate Web service discovery, Web service invocation and Web service composition and interoperation.
