Straccia U. Towards a Fuzzy Description Logic for the Semantic Web. The document will be submitted to Conference: European Semantic Web Conference 2005, Technical report, 2004.
In this paper we present a fuzzy version of ${cal SHOIN}(D)$, the corresponding Description Logic of the ontology description language OWL DL. We show that the representation and reasoning capabilities of fuzzy ${cal SHOIN}(D)$ go clearly beyond classical ${cal SHOIN}(D)$. We present its syntax and semantics. Interesting features are that concrete domains are fuzzy and entailment and subsumption relationships may hold to some degree in the unit interval $[0,1]$.
