Towards a Systematic Account of Different Semantics for Logic Programs
Pascal Hitzler
In [Hitzler and Wendt 2002, 2005], a new methodology has been proposed which allows to derive uniform characterizations of different declarative semantics for logic programs with n…
Default reasoning over domains and concept hierarchies
Pascal Hitzler
W.C. Rounds and G.-Q. Zhang (2001) have proposed to study a form of disjunctive logic programming generalized to algebraic domains. This system allows reasoning with information wh…
The Integration of Connectionism and First-Order Knowledge Representation and Reasoning as a Challenge for Artificial Intelligence
Sebastian Bader, Pascal Hitzler, Steffen Hoelldobler
Intelligent systems based on first-order logic on the one hand, and on artificial neural networks (also called connectionist systems) on the other, differ substantially. It would b…
Corollaries on the fixpoint completion: studying the stable semantics by means of the Clark completion
Pascal Hitzler
The fixpoint completion fix(P) of a normal logic program P is a program transformation such that the stable models of P are exactly the models of the Clark completion of fix(P). Th…
A uniform approach to logic programming semantics
Pascal Hitzler, Matthias Wendt
Part of the theory of logic programming and nonmonotonic reasoning concerns the study of fixed-point semantics for these paradigms. Several different semantics have been proposed d…
