Most of the systems presented to date deals with RDF format so they are limited in actually addressing the knowledge base features from the ontology based on OWL semantics. Now, there is a need that actual OWL features i.e. rules and axioms must be addressed to give precise answers to the user queries. This paper presents an interface to OWL ontology which also considers axioms and restrictions that can result in inferring results in understanding user queries and in selecting appropriate SPARQL queries for getting better interpretation and answers.
