The CIFF Proof Procedure for Abductive Logic Programming with Constraints
Abstract. We introduce a new proof procedure for abductive logic programming and present two soundness results. Our procedure extends that of Fung and Kowalski by integrating abduc...

Type Classes and Overloading in Higher-Order Logic
Type classes and overloading are shown to be independent concepts that can both be added to simple higher-order logics in the tradition of Church and Gordon, without demanding more...

Using Call/Exit Analysis for Logic Program Transformation
A technique for transformation of definite logic programs is presented. A first phase performs an analysis of the extended call/exit patterns of the source program. It is shown tha...

PSPACE Automata for Description Logics
Tree automata are often used for satisfiability testing in the area of description logics, which usually yields ExpTime complexity results. We examine conditions under which this ...
