Abstract:    (5RP)

We describe a prototype implementation of a semantic filtering capability added to an existing XML-based publish and subscribe infrastructure. An ontology is used to provide vocabulary for expressing both 1) the semantic annotations that characterize the published documents and 2) the subscriptions specifying the class of documents to be routed to a given client. A description logic (DL) classifier is used to determine which subscribers an incoming document is routed to. We outline the key elements of the ontology for an enterprise activity reporting domain and give some sample annotations and subscriptions. This is the basis for describing a number of scenarios showing how this filtering capability could be used in practice. We critically analyze the suitability of a DL language and reasoner in general, and the particular implementation choices (OWL, FaCT and OilEd) for performing this task. A key result of the work is to demonstrate the importance of testing semantics-based technologies on practical problems. We discovered a number of new and interesting areas for future work, which in turn can direct the focus of the research community.    (5RQ)

Dr. Michael Uschold is a research scientist at Boeing Phantom Works, the advanced research and development organization of The Boeing Company. His interests center around the field concerned with the development and application of ontologies. This includes the emerging Semantic Web, semantic integration, knowledge management, and more recently, in the area of world modeling for autonomous vehicle navigation. For over two decades, Mike has been involved in a wide range of activities in these areas, including research, applications and teaching. Dr. Uschold is on the industrial advisory boards of various projects and initiatives related to the Semantic Web and other knowledge technologies. He is very active in organizing and participating in workshops and conferences on these topics.    (5RW)

He received his B.S. in mathematics and physics at Canisis College in Buffalo, N.Y in 1977, a Masters in computer science from Rutgers University in 1982, and a PhD in Artificial Intelligence from The University of Edinburgh in 1991. Before arriving at the Boeing Company in 1997, Dr. Uschold was a senior member of technical staff in the Artificial Intelligence Applications Institute (AIAI) at the University of Edinburgh. He has also been a lecturer and a research associate at the Department of AI at the University of Edinburgh.    (5RX)
