Abstract: How to build knowledge management system is becoming a hotpoint of current research. The reconfiguration and evolution ability to adapt the change of environment are the hard points of research. To get the reconfiguration, the KM system based on the domain ontology can be built. However, as the time goes by, the structure and the content of the domain knowledge change. Hence the ontology evolution, knowledge evolution and the consistent model become the key problems that must be resolved. The key issues of ontology evolution and version management are analyzed. The strategy and the algorithm are introduced. Then a framework for ontology evolution is propsed and this framework is adopted into the knowledge management system.The application of this framework and the directions of future research are introduced.

Key words: knowledge management system, ontology evolution, version management, consistent

摘要： 如何建立知识管理系统的研究是目前的一个研究热点，其中系统的可重构(可配置)性以及适应环境变化的进化能力是研究中的难点。通过基于企业本体来建立知识管理系统的方法，可以实现系统的可重构性。但是随时间变化，企业领域知识的结构、内容也在不停变化，因而本体进化、知识进化方法及一致性模型的研究成为必须要解决的问题。该文分析了本体进化及版本管理的一些关键问题，讨论了相应策略和算法，给出一个本体进化管理框架并引入到知识管理系统的开发中，并介绍了实际的应用情况和今后的研究方向。
