Design of Ontologies for Dialogue Interaction and Information Extraction
Annika Flycht-Eriksson · 2003
In this paper we discuss how information extraction can be integrated in a dialogue system, with the focus on ontologies as domain knowledge sources. The requirements of domain ontologies are analysed in light of the tasks performed in the two areas, and implications for the design and construction of domain ontologies are presented. One of the most important features of a domain ontology to be used for both dialogue interaction and information extraction is that it should incorporate both the users ’ conceptualisation of the domain and the conceptualisation present in the information sources. It is shown how this can be done and with the constructed ontology as a starting point more detailed design issues are considered. 1
