摘要: 传统的构件库描述和检索方法无法对构件的语义关系进行描述,阻碍了用户对构件的应用。采用本体论的方法建立构件属性的描述模型,实现构件查询基于本体的语义扩展。给出构件属性与用户需求之间相似度的计算方法,帮助用户迅速准确找到需要的构件。

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
