In this paper we propose an architecture for dialogue systems that incorporate information extraction, thereby providing natural and efficient access to unstructured information sources. A key feature of the architecture is the use of ontologies as shared domain knowledge sources. We discuss how ontologies can be used for various tasks. with focus on question analysis, dialogue interaction and information extraction.
