In this paper we develop a generic declarative diagnoser for normal logic programs that is based on tree search. The soundness and the completeness of the diagnoser are proved. The...
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...
In this paper we will present a formal framework, based on the notion of extraction calculus, which has been successfully applied to define procedures for extracting information fr...
Logic programming with negation offers a compelling approach to abductive reasoning. This paper shows a simple view of abduction in this context for the completion semantics, unde...
Abstract. In this paper, we propose an approach to translating any ALC ontology (possible inconsistent) into a logically consistent set of disjunctive datalog rules. We achieve thi...
