| 摘 要： | 以概念格理论为基础,利用形式概念分析的方法构建出社区知识热点主题概念格,以概念格中最大频繁项聚类挖掘社区用户知识需求的共性特征。在此基础上提出了社区用户知识需求的三项特征,即社会影响性、时间迁移性、需求层次性。并以此建立了社区用户知识需求模型。

| Abstract: | Based on concept lattice theory,this article constructs concept lattice of hot topic of community knowledge by formal concept analysis,and mines the common characteristics of knowledge needs of the user by most frequent item in the concept lattice clustering.On this basis,three characteristics of knowledge needs of community users were presented: social impact,time migration,demand hierarchy,and establishes the demand model of knowledge to community users. |
