Hybrid logics are a principled generalization of both modal logics and description logics, a standard formalism for knowledge representation. In this paper we give the first const...
Abstract. We present the design of our implemented modal logic programming system MProlog. This system is written in Prolog as a module for Prolog. Codes, libraries, and most featu...
We provide complete axiomatizations for several fragments of XPath: sets of equivalences from which every other valid equivalence is derivable. Specifically, we axiomatize downwar...
We introduce our implemented modal logic programming system MProlog. This system is written in Prolog as a module for Prolog. Codes, libraries, and most features of Prolog can be u...
This paper is devoted to the study of self-referential proofs and/or justifications, i.e., valid proofs that prove statements about these same proofs. The goal is to investigate wh...
