Knowledge map creation in virtual communities of practice using hierarchical growing cell structures
基于层级成长单元结构算法的虚拟实践社区知识地图的构建

A knowledge map creation approach was proposed to increase the efficiencies of browsing and searching knowledge objects in virtual communities of practice.Growing cell structures algorithm was improved and hierarchical growing cell structures was proposed to cluster knowledge objects in virtual communities.Then topics were automatically selected for each cluster by the LabelSOM algorithm,and hierarchical knowledge map was created.Experimental results show that the clustering performance of the proposed appr...
