ONTOSEARCH2: Searching ontologies semantically
Edward Thomas, Jeff Z. Pan, Derek H. Sleeman · 2007
Abstract. While the Web makes an increasing number of ontologies widely available for applications, how to discover ontologies becomes a more challenging issue. Existing approaches are mainly based on keywords and metadata information of ontologies, rather than semantic entailments of ontologies. In this paper, we present an ontology search engine, ONTOSEARCH2, which provides three approaches to searching ontologies semantically. These approaches take advantage of ON-TOSEARCH2’s efficient query answering capability. 1
