WOW-Gers I have taken a stab at a categorization of the use cases - I find 3 natural categories, 1 almost a natural category (two ideas that might be related, but don't fit totally) and only a couple of loose ends I could not figure out exactly where to fit. In addition, some technical issues that might cross cut seem to come out. There are listed below. I would be happy if we could end up with 4 total groups -- winnowing my 4 categories down to 3, and developing the "cross cutting technologies" to become more focused (to be the base for the sort of "requirements" Peter Patel-Schneider argued for earlier) Please discuss and let's see if we can resolve by Thurs. Jim H ========== [Note WOL is only an acronym for Web Ontology Language at this point- does not represent commitment to this name] Use cases - rough categorization proposal: 1) Web Services WSDL is only a starting place, seems to stress interconnection, but not content. WOL has potential to be used for better advertising (via hierarchy/classification), for connecting advertisements to ontologies, and for exploring the compositionality of services. 2) Archives/CatalogsLarge data (or image) sets/web site management All of these areas focus on the use of ontologies in the management of large scale information sources. Includes need for matching, classification, default reasoning. "Traditional" metadata (i.e. document markup) would fall in this category. 3) Content Interoperability (a/k/a/ agent markup) RDF has advantage over XML in allowing easy merging of content found on different sites/resources, and the use of the combined sources. Use cases include linking of databases (DB schemas), coupling data to pages, linking instance data to ontologies. Also allows linking of ontology to ontology for mapping of vocabulary, etc. 4) Adaptation of content to user/device (real time/sensors?) Use of ontologies to help determine what info to show to whom when, or to be the information shown (i.e. in PalmDAML the user can browse the semantics separate from the source pages). The real-time and embedded sensor area seems to fit in best here - but I admit I'm pushing a little. Loose ends: open hypermedia contradiction/inconsistencies Technical issues that could be address in some or all versioning ontology-based search domain-mapping/ontology linking (how much is commited to by a link) ontology querying rapid creation of large ontologies ? -- Professor James Hendler hendler@cs.umd.edu Director, Semantic Web and Agent Technologies 301-405-2696 Maryland Information and Network Dynamics Lab. 301-405-6707 (Fax) AV Williams Building, Univ of Maryland College Park, MD 20742 http://www.cs.umd.edu/users/hendler
