The link relationship is used to divide communities in traditional community detection algorithms, which has the disadvantage of detecting the non-link relationship and is bad for the division accuracy. In this paper, it analyzes the text information in nodes and extracts the hidden topic information to determine the relationship of the communities on topic. Based on this, it designs an optimized Dirichlet allocation model to divide the communities by topics. Furthermore,a community detecting algorithm of o...
