Abstract: The Semantic Web should enhance the current World Wide Web with reasoning capabilities for enabling automated processing of possibly distributed information. In this paper we describe an architecture for Semantic Web reasoning and query answering in a very general setting involving several heterogeneous information sources, as well as domain ontologies needed for offering a uniform and source-independent view on the data. Since querying a Web source is very costly in terms of response time, we focus mainly on the query planner of such a system, as it may allow avoiding the access to query-irrelevant sources or combinations of sources based on knowledge about the domain and the sources. This work is part of a larger research project, ROTEL, aimed at combining Semantic Web and Natural Language technology.

Keywords: Semantic Web, constraint reasoning, intelligent information integration, ontologies, query planning.
