Abstract    (43Y)

The Computer Science field of Ontology has been progressing in a scatter-shot manner, and there has been little attempt to formalize the techniques used and lessons learned from research. OntoClean was one of the first attempts to build a formal foundation for ontological analysis, which helped identify the most common logical modeling mistakes and the justifications for why they are, in fact, mistakes. In this talk, I present an overview of the OntoClean methodology for ontological analysis, and highlight the common modeling problems with examples.    (43Z)

Chris Welty is a Research Scientist at the IBM T.J. Watson Research Center in New York. Previously, he taught Computer Science at Vassar College, taught at and received his Ph.D. from Rensselaer Polytechnice Institute, and accumulated over 14 years of teaching experience before moving to industrial research. Chris' principal area of research is Knowledge Representation, specifically ontologies and the semantic web, and he spends most of his time applying this technology to Information Retrieval and, in the past, Software Engineering. Dr. Welty serves on the steering committee of the Formal Ontology in Information Systems Conferences, as program chair of the Knowledge Representation Conference , on the advisory board of IJCAI-05 on the editorial boards of AI Magazine and The Journal of Web Semantics, was an editor in the W3C Web Ontology Working Group. Chris Welty's work on ontologies and ontology methodology has appeared in CACM, and numerous other publications.    (446)

Dr. Welty also was the first ACM SIGART Information Director, and was responsible for establishing the SIGART Electronic Information Service. He was the editor in chief of the former ACM SIGART intelligence Magazine, from its initial planning in 1996 through to its ultimate demise in 2001, and has been an active ACM member since 1990.    (447)
