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。 For some knowledge management systems, there is the problem of low precision and poor efficiency of ontology evolution and knowledge push, and the sociality of knowledge management is integrated into the application technology. A new concept model of knowledge management is delineated. Based on ontology evolution and Information Retrieval linkage development of distributed knowledge management system (ERKMS), while the corresponding ontology evolution algorithm. Through an instance of knowledge push in African travel routes, the performance of ERKMS is measured by five indicators, including recall rate, precision ratio, F function, and the discard rate and the resolution rate proposed in this paper. The verification proves that ERKMS has good The evolution of ontology and the efficiency of knowledge push.
