Straccia U. Towards a Fuzzy Description Logic for the Semantic Web (Preliminary Report). In: 2nd European Semantic Web Conference (ESWC-05) (Heraklion, Greece, 29 May - 1 June 2005). Proceedings, vol. LNCS 3532 pp. 167 - 181. (Lecture Notes in Computer Science). Springer Verlag, 2005.
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 SHOIN(D) go clearly beyond classical 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].
