On fuzzy Semantic Web Services

Semantic Web Services (SWSs) extend Web Services in the context of Semantic Web, providing a well-defined semantics in order to make them computer-interpretable, use-apparent, and agent-ready. However, current Semantic Web technologies are not appropriate to deal with imprecise and vague knowledge, inherent to several real world domains. In this paper, we introduce the notion of fuzzy Semantic Web Services, or OWL-S SWSs with a fuzzy domain ontology. This way, both service providers and users can use fuzzy logic to advertise services and request their needs, respectively. In particular, we present an architecture for developing fuzzy SWSs, as well as a framework for fuzzy ontology generation.
