"In the context of new work on distributed computation, Semantic Web Services (SWSs) go beyond current services by adding ontologies and formal knowledge to support description, discovery, negotiation, mediation and composition. This formal knowledge is often strongly related to informal materials. For example, a service for multi-media content delivery over broadband networks might incorporate conceptual indices of the content, so that a smart VCR (such as next generation TiVO) can reason about programmes to suggest to its owner. Alternatively, a service for B2B catalogue publication has to translate between existing semi-structured catalogues and the more formal catalogues required for SWS purposes. To make these types of services cost-effective we need automatic knowledge harvesting from all forms of content that contain natural language text or spoken data."
The winner of the Semantic Web Challenge will be announced, papers and demos. Related to the Semantic Web Enabled Web Services homepage.
