Critical review of the Journal Article: Ontologies describing concepts and relations in a specific domain are necessary for knowledge representation and knowledge exchange. Waterson and Preece define ontology as he Specification of Shared Knowledge. Ontologies (semantic data) facilitate the usability of e-technology and realize its full power. here are several Languages, Tools and Formalisms that accompany the term ontology. Among those languages, we enumerate XML (Extensible Markup Language), RDF (Resource Description Framework), RDFS (RDF Schema), DAML+OIL and OWL that are used in several contexts (compatibility with other concepts, expressiveness, etc.). Moreover, there exist several ontology formalisms with a definite advantages and drawbacks, which support particular features. Ontologies should be created for a specific function in the most appropriate formalism satisfying needs of a fine target community. (Slimani 2015)
