Sound and Complete Inference Rules for SE-Consequence
The notion of strong equivalence on logic programs with answer set semantics gives rise to a consequence relation on logic program rules, called SE-consequence. We present a sound...

Yet Another Proof of the Strong Equivalence Between Propositional Theories and Logic Programs
Recently, the stable model semantics was extended to the syntax of arbitrary propositional formulas, which are beyond the traditional rule form. Cabalar and Ferraris, as well as Ca...

A Reasoner for Simple Conceptual Logic Programs
Open Answer Set Programming (OASP) can be seen as a framework to represent tightly integrated combined knowledge bases of ontologies and rules that are not necessarily DL-safe. The...
