Fuzzy Ontology Model and Its Application in Semantic Web Service Description and Discovery

Semantic Web service makes service representation and discovery more machine-understandable by adopting ontology semantics. However these representations are inadequate to descript and discover services imprecisely requested by human. Fuzzy ontology is an extension of the domain ontology. It is more suitable to describe the domain knowledge for uncertainty representation and reasoning. In this paper, we first construct a fuzzy ontology model based on domain ontology to facilitate fuzzy computation of Web service. Then its application to Web service description and discovery is presented. Finally, a framework is given to show how to use fuzzy ontology for Web service.
