The Semantic Web is a vision of the next generation Web, in which semantic markup will make Web resources more accessible to automatic processes. Description Logics (DLs) are of cr...
Abstract. WSML presents a framework encompassing different language variants, rooted in Description Logics and (F-)Logic Programming. So far, the precise relationships between thes...
This paper describes our current activities to supply extended reasoning support to knowledge engineers who are building terminologies using Description Logics (DL) reasoners. The...
We present lower bounds on the computational complexity of satisfiability and subsumption in several description logics. We interpret these lower bounds as coming from different...
