In this paper, we describe an approach to semantic Web service modeling for e-business environment. Previous research has suggested a method to dynamically convert components to web service. And the semantic Web should enable greater access not only to content but also to services on the Web. It needs semantic service discovery for components. So, we add ontology-based framework to Web service generation system from components. In other words, we suggest a way to combine ontology framework and Web service generation dynamically. To do that, we use UML model to be a bridge between web Service and ontology. The UML Model is a useful tool to visualize and map from OWL and WSDL.
