The paper describes a novel methodology to compute stable models in Answer Set Programming. The proposed approach relies on a bottom-up computation that does not require a prelimin...
Abstract. Tableau calculi are the state-of-the-art for reasoning in description logics (DL). Despite recent improvements, tableau-based reasoners still cannot process certain knowl...
Statecharts and Petri nets are two popular visual formalisms for modelling complex systems that exhibit concurrency. Both formalisms are supported by various design tools. To enabl...
In this paper we present an embedding of propositional production systems into µ-calculus, and first-order production systems into fixed-point logic, with the aim of using these...
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...
