We discuss a declarative characterization of inheritance in logic programming. Our approach is inspired both by existing literature on denotational models for inheritance and by e...
We integrate a logic programming language into Meta-S, a flexible and extendable constraint solver cooperation system, by treating resolution as constraint solver. This new approac...

It is well-known that knowledgebases may contain inconsistencies. We provide a measure to quantify the inconsistency of a knowledgebase, thereby allowing for the comparison of the...
In this paper, consistency is understood in the standard way, i.e. as the absence of a contradiction. The basic constructive logic BK c4 , which is adequate to this sense of consis...
A propositional system of modal logic is second-order if it contains quantifiers p and p, which, in the standard interpretation, are construed as ranging over sets of possible worl...
