摘要： 在构件的描述与检索中引入本体，可以更好地表示构件间的语义信息。本体是对知识的表达，可以对知识进行有效的组织和管理，实现知识共享和重利用，从而充分有效地利用知识资源。但是知识不是一成不变的，基于本体描述的构件库系统中的本体库需要更新和维护。该文提出了一种本体演化理论框架，探讨了其研究方向和重点。

Abstract: By introducing ontology into the field of software-component description and retrieval, the semantic information among the components can be presented more precisely. Ontology is the representation of knowledge. It can make knowledge sharable and reusable by managing it efficiently. The utility of knowledge resource can be exploited more effectively.

This paper proposes a framework of ontology evolution from owl files, the research direction and key points are also discussed.

Key words: Ontology, Component description, Evolution model
