摘要： 社区结构是复杂网络的重要特征之一，该文通过构造基于兴趣的论坛用户网络，成功地将社区结构发现的理论与方法应用于论坛热点主题的自动发现，提出了极大社区的概念和反复挖掘极大社区的方法，发现网络结构和论坛主题在反复挖掘过程中均几乎保持不变。仿真结果表明，提取效果令人满意。

Abstract: Community structure is one of important characteristics of complex networks. Community finding algorithm is successfully applied in the detection of forum hot topic in this paper, and the following conclusions are obtained: the concept of maximal community and the method of repetitive dig of maximal community is proposed, and it is found that either network structure or forum hot topic is hardly changed. The simulation results show that the method works well.

Key words: complex network, community structure, maximal community, forum topic
