In this paper we propose a framework for semantic Web service discovery that communicates between multi agent system and Web services without changing their existing specifications and implementations by providing a broker. We explained that the ontology management in the broker creates the user ontology and merges it with general ontology (i.e. WordNet, Yago, Wikipedia …) and recommends the created WSDL based on generalized ontology to selected Web service provider to increase their retrieval probability in the related queries. In the future works, we solve inconsistencies during the merge and will improve matching process and will implement the recommendation component.
