The latest ontology languages can be translated into a description logic (DL), thus providing them with a formal semantics and associated reasoning procedures. We introduce the or...
Abstract. Inconsistency handling in expressive description logics is an important problem because inconsistency may naturally occur in an open world. In this paper, we present the ...
Effective systems for expressive description logics require a heavily-optimised subsumption checker incorporating a range of optimisation techniques. Because of the correspondence...
Mechanical systems, of the kinds which are of interest for qualitative reasoning, are characterized by a set of real-valued parameters, each of which is a piecewise continuous fun...
We present an approach towards a formal dynamic semantics for UML using ASM. We aim to remain as close as possible to the standard definition of UML and to cover the operational pa...
