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。 The community structure is one of the most important characteristics of a complex network. By constructing interest-based forum user networks and successfully applying the theories and methods of community structure discovery to the automatic discovery of hot topic topics in the forum, the concept of community community The method of mining the great community, found that the network structure and forum topics in the process of mining repeatedly remained almost unchanged. Simulation results show that the extraction results are satisfactory.
