Abstract In order to study the features of microblog following relationship network, the analysis method based on complex network is applied to analyze the following relationship of Sina Microblog in this paper.Firstly,the K-core decomposition operation is performed on a microblog following relationship network to obtain a core user's relationship network. Secondly, the features of online community network and those of realistic society network can be received in the K-core network by computing the basic parameters of the K-core network, following ratio and degree correlation. Finally, a conclusion can be obtained that the community characteristic of the network structure is very obvious by community detecting on the K-core network and analysis of the node centrality, reciprocity and the role of brokerage. Experimetnal results show that the research work of this paper can provide effectively a fundamental empirical analysis for related applications.
