Relationship-Centric Ontology Integration
Abstract
Informal ontologies can result from the successive extraction of RDF (Resource Description Framework) from XML and then OWL (Web Ontology Language) from RDF. This two-stage extraction affords separate and distinct opportunities for the development of an integrated ontology. Working directly with RDF, resulting integrated informal ontologies are shaped heavily by relationships. The RDF-centric approach also allows inconsistencies and redundancies to be resolved. In contrast, the class/property/individual bias inherent in informal ontologies represented via OWL affords a very different, more traditional perspective for ontology integration. Using a semantic framework developed for the Global Geodynamics Project (GGP), the RDF-centric approach for ontology integration is illustrated. And although this approach is effective and efficient on balance, the incorporation of feature-based annotations illustrates how integrated ontologies may challenge the computational completeness and decidability of the resulting representation in OWL.
