Abstract

In the area of data and knowledge management, ontology-based query answering (OB QA) is becoming more and more a relevant task [2,3]. In fact, many organizations and autonomous contributors are generating the so called "Web of Data", making publicly available Semantic Web repositories built either from scratch or by translation of existing data in ontological form. Contemporarily, database technology providers --- such as Oracle, Ontotext, and Ontoprise --- have started to build ontological reasoning modules on top of their existing software. Ontological reasoning is also the goal of several research-based systems, such as Quest, Owlgres, Owlim, and QuOnto, just to cite a few.
