We equip ordered logic programs with negation as failure, using a simple generalization of the preferred answer set semantics for ordered programs. This extension supports a conven...
In spite of the increasing effort spent on building ontologies for the Semantic Web, little attention has been paid to the impact of these ontologies on knowledge-based intelligen...
Abstract. Qualification has been recently introduced as a generalization of uncertainty in the field of Logic Programming. In this paper we investigate a more expressive language f...
In this paper, we use autoepistemic reasoning semantics to classify various semantics for disjunctive logic programs with default negation. We have observed that two different typ...
Abstract. In this PhD project, we deal with the issue of code duplication in logic programs. In particular semantical duplication or redundancy is generally viewed as a possible se...
