Hierarchical graph definitions allow a modular description of graphs using modules for the specification of repeated substructures. Beside this modularity, hierarchical graph de...
Abstract. We show that subsumption problems in EL and related description logics can be expressed as uniform word problems in classes of semilattices with monotone operators. We us...
Hybrid logics are a principled generalization of both modal logics and description logics. It is well-known that various hybrid logics without binders are decidable, but decision p...
This paper presents ontology-based architecture for pattern recognition in the context of static source code analysis. The proposed system has three subsystems: parser, OWL ontolog...
Abstract. WSML presents a framework encompassing different language variants, rooted in Description Logics and (F-)Logic Programming. So far, the precise relationships between thes...
