Abstract. leanK is a "lean", i.e., extremely compact, Prolog implementation of a free variable tableau calculus for propositional modal logics. leanK 2.0 includes additio...
Forthcoming in the Journal of Aritificial Intelligence We introduce mathematical programming and atomic decomposition as the basic modal (T-Box) inference techniques for a large c...
This paper compares Propositional Dynamic Logic of Non-Regular Programs and Fixpoint Logic with Chop. It identifies a fragment of the latter which is equiexpressive to the former....
Abstract. Description Logics (DLs) are a family of logic based knowledge representation formalisms. Although they have a range of applications (e.g., configuration and information...
Abstract. The coupling of description logic reasoning systems with other reasoning formalisms (possibly over the Web) is becoming an important research issue and calls for advanced...
