Finding shows that there are 12 criteria for evaluation of ontology languages such as constructs and conceptualization of domain, specification perspective, expressiveness, formality, popularity and etc. All of ontology languages have 3 layers or features and their perspective are structural. Expressiveness in KIF and OWL Full is high and in RDF(s) and OWL DL is medium. Syntax and semantic criteria in all of languages is formal and OWL is the most popularity languages.
