Integrating Domain Knowledge into a Generic Ontology
Sofia Stamou, Informatics Dpt, Riga Feraiou, Dimitris Christodoulakis · 2004
In this paper we report on a combined ontology of various subject domains that evolved after merging ontological content that we harvested from the Suggested Upper Merged Ontology (SUMO), MultiWordNet Domains and BalkaNet. First, we present the process we followed for integrating SUMO and MWND into a common resource. Then we describe how we enriched the resulting joint ontology with an upper layer of domain concepts, which were borrowed from the topics used in popular Web directories to categorize Web pages. Finally, we address the integration of the enriched ontology with BalkaNet’s Inter-Lingual-Index (BILI). BILI comprises a subset of WordNet 2.0 synsets that have been linked to their semantic equivalents across six Balkan wordnets. Currently, BILI forms a combined ontology of multiple topics and can serve, among other, as a referential structured resource for categorizing documents into topics.
