Supporting the Reuse of Global Unique Identifiers for Individuals in OWL/RDF Knowledge Bases

摘要

In the current state of Semantic Web knowledge representation, it is fairly common that individuals in ontologies have different identifiers even if they are meant to denote the same object in the real world. This makes data integration at the level of individuals quite difficult. In this demonstration, we show two plug-ins called 0kkam4N and Okkam4P developed for the NeOn Toolkit and Protege software respectively, which support the reuse of globally unique identifiers for individuals in OWL/RDF knowledge bases. The key idea is that users are given a chance to look for an existing URI in the publicly available Entity Name System for the corresponding individual in the local OWL/RDF knowledge bases. They are available and tested for the latest official release versions, the NeOn Toolkit 1.2 and Protege 3.4.
