In this paper we describe a fuzzy Description Logic reasoner which implements resolution in order to provide reasoning services for expressive fuzzy DLs. The main innovation of thi...
We describe ongoing research to support the construction of terminologies with Description Logics. For the explanation of subsumption we search for particular concepts because of t...
We extend the theory about terminological default reasoning by using a logical base language that can represent spatioterminological phenomena. Based on this description logic lang...
