D1.2.10v2 Ontology repositories and content evaluation

Vrandecic, Denny; Sure-Vetter, York; Palma, Raul; Santana, Francisco

Abstract:
In this deliverable we present results obtained from the work described in the first version of this deliverable (D1.2.10) about ontology repositories. In particular, we provide an overview of the sustainability of the Ontology Metadata Vocabulary (OMV), the proposal of a hierarchy for the classification of ontology domains and evaluation results for the distributed ontology metadata repository (Oyster). Furthermore, we discuss the flow of knowledge between Oyster and the ontology metadata portal Onthology that rely on the content evaluation metrics described at the end of the deliverable. Therefore, the second part of the deliverable discusses how to properly define metrics for ontologies, and introduce the notions of ontology normalization for measuring, and of stable metrics. This will help to properly define better ontology metrics in subsequent research in this area. The normalization has been implemented in a prototype as part of the KAON2 OWL Tools (source code available for download at OntoWare.org). Parts of this work have been already accepted for publication at the European Semantic Web Conference (ESWC2007).
