TY - CONF N2 - Both ontology content and ontology building tools evaluations play an important role before using ontologies in Semantic Web applications. In this paper we try to assess ontology evaluation functionalities of the following ontology platforms: OilEd, OntoEdit, Protégé-2000, and WebODE. The goal of this paper is to analyze whether such ontology platforms prevent the ontologist from making knowledge representation mistakes in concept taxonomies during RDF(S) and DAML+OIL ontology import, during ontology building and during ontology export to RDF(S) and DAML+OIL. Our study reveals that most of these ontology platforms only detect a few mistakes in concept taxonomies when importing RDF(S) and DAML+OIL ontologies. It also reveals that most of these ontology platforms only detect some mistakes in concept taxonomies during building ontologies. Our study also reveals that these platforms do not detect any taxonomic mistake when exporting ontologies to such languages.
