Abstract—The semantic web can be considered as a semantic expansion for the web and the ontologies act as the backbone of semantic web. Over these years an increasing number of ontologies have been developed. The development of new ontologies does not tap the full potential of existing knowledge sources and ongoing ontology engineering methodologies do not address ontology reuse to a satisfactory extent yet. Selecting the desired ontology from existing ontologies is essential for ontology reuse. Several works has been done for ontology selection. However, in these cases, it is almost impossible to find an ontology that includes all the concepts matched by the search terms at the semantic level. To deal with this, the proposed work uses combination of Content Based Ontology Ranking and Ontology Rank model consisting of selection standards and metrics based on better semantic matching capabilities. The model proposed presents two novel features different from previous research models. First, it enhances the ontology selection and ranking method practically and effectively by enabling semantic matching of taxonomy or relational linkage between concepts. Second, it identifies what measures should be used to rank ontologies in the given context and what weight should be assigned to each selection measure. Experimental result provides better result when compare with the existing ranking system.
