ABSTRACT
The Semantic Web is many things: an ambitious vision for the future of the Internet; a lively research area; a set of standards activities at the World Wide Web Consortium; a technology base of Web-oriented knowledge representation languages, reasoners, and tools; and a growing collection of shared ontologies, knowledge bases, collaborative activities and communities supported by these technologies. The potential of the Semantic Web goes well beyond its applications to information discovery and querying. In particular, it encompasses the automation of Web-based activities and Web-accessible devices as well. When it becomes widespread, the ability to deploy, discover, and use online processing resources and devices, in an significantly automated fashion, will likely be viewed as a major transformation of the Web. Semantic Web services technology is the embodiment of this developing trend.
Work on Semantic Web Services is complementary (to a degree) with commercial work on Web services, and provides greater expressiveness in describing services in a way that software agents can reason about. This reasoning, in turn, can support more powerful and more fully automated approaches to Web service tasks such as service discovery, selection, invocation, execution, composition, monitoring, and recovery. This presentation will explain the concepts embodied in Semantic Web Services, show how it ties in with developing industry standards, and discuss some existing applications. A perspective will be given on the status of work in this field, tools under development to support its use, and next steps towards realizing its promise.
BIOGRAPHY
David Martin is a researcher in the Artificial Intelligence Center at SRI International, where he has been on the research staff since 1994. He has worked extensively in the field of agent-based systems, and was one of the principal designers of the Open Agent Architecture (OAA). He has also worked in the fields of software design environments, natural language processing, and Semantic Web. He was a Principal Investigator for SRI's DAML (DARPA Agent Markup Language) project, and served as chair of the research coalition that developed OWL-S, a service description language for the Semantic Web. He is also co-chair of the language subcommittee of The Semantic Web Services Initiative (SWSI).
