Abstract: The traditional methods of description and retrieval of component database cannot describe the semantic relation of components, obstructing their application. Therefore, a description model of components was founded by means of ontology, in order to carry out semantic extension of component retrieval. The method that works out the similarity value between function of component and requirement of users was presented. It helps users to quickly and precisely find the components in need.

Key words: component retrieval, ontology, semantic, component description, similarity
