Study on component hierarchical retrieval based on ontology

The method of component description and retrieval is a hot subject of research in component-based software development. In order to describe the component more completely and accurately, an approach based facet and ontology is brought forward. The method proposed in the paper firstly choose the exactly type and application components, then choose components further through component´s functional match, at last users make final choose after looking over all the candidate components. The description method of components is the base for users to find the exact components. An implementation of the proposed approach shows that the users can select components quickly and precisely.
