    A proposition of knowledge management methodology for the purpose of reasoning with the use of an upper-ontology
    (2007) Szymański, Kamil; Dobrowolski, Grzegorz; Koźlak, Jarosław; Zygmunt, Anna
    This article describes a proposition of knowledge organization for the purpose of reasoning using an upper-ontology. It presents a model of integrated ontologies architecture which consists of a domain ontologies layer with instances, a shared upper-ontology layer with additional rules and a layer of ontologies mapping concrete domain ontologies with the upper-ontology. Thanks to the upper-ontology, new facts were concluded from domain ontologies during the reasoning process. A practical realization proposition is given as well. It is based on some popular Semantic Web technologies and tools, such as OWL, SWRL, nRQL, Protege and Racer.
