摘　　要：企业知识管理系统中的知识地图面临知识存储分散、来源复杂、类型多样且不断变化等问题,严重影响了企业知识共享和知识重用。提出一种基于企业本体自动构建知识地图,并根据用户搜索动态维护和扩充知识地图的方法,最后对知识地图构建、扩充和利用进行了实例分析。Knowledge map in enterprise knowledge management system had many problems with knowledge such as scattered storage, complex sources, diverse types and frequent changes, so that knowledge sharing and reusing were impacted. An approach was proposed, in which the knowledge map was built based on the enterprise library and extended according to users＇ search behavior. And a sample analyze for building, extending and leveraging the knowledge map was presented.
