Evaluation of extended error taxonomy for OWL2

Ontology Evaluation is one of the most critical phases in ontology engineering. Applications depending upon ontology can have serious and appalling problems if ontology itself is infected with errors. Therefore, ontology should be consistent, complete and errors free. An error taxonomy using OWL constructs and axioms was developed to overcome the possibility of occurring errors in ontology. Recently, some new features have been proposed in OWL2 specification to overcome the limitation of expressive power of OWL. In this paper we evaluate the extended error taxonomy of OWL with the new features of OWL2. We also evaluate that while using OWL2 features, occurrence of possibility of new types of errors get reduced or not. On the basis of different examples for each error, we conclude that the error taxonomy is also valid for OWL2. This is because of the fact that every OWL ontology is a valid OWL2 ontology and every OWL2 ontology (excluding new features) is also a valid OWL ontology. The zero level circulatory errors can also be removed if we use the reflexive property and self restriction (local reflexive) property of OWL2. Otherwise, we have to generate a warning omission for zero level circulatory error.
