摘　　要：针对一些知识管理系统存在本体进化和知识推送精确度低、效率差的问题,将知识管理的社会性融入到应用技术之中,描绘一种新的知识管理概念模型,给出基于知识本体进化和信息检索联动发展的分布式知识管理系统(ERKMS),同时提出相应的本体进化算法。通过一个非洲旅游线路相关知识推送的实例,结合查全率、查准率、F函数,以及本文提出的丢弃率和判准率共5项指标衡量ERKMS的性能,验证证明,ERKMS具有较好的本体进化和知识推送的效率。Aim at the problem of low accuracy and poor efficiency of ontology evolution and knowledge push in theknowledge management system,takes the social attributes into the application technology of the knowledge management.Describes a new conceptual model of knowledge management, proposes a distributed knowledge management system（ERKMS）based on joint development of ontology evolution and information retrieval, and puts forward the appropriateontology evolutionary algorithm. Through an African tour line road knowledge push instance, combines recall, precision, Ffunctions, as well as the discard rate and accurately determine rate,total of five performance indicators to measure ERKMS.Experiment shows that ERKMS has a better efficiency of ontology evolution and knowledge push.
