Abstract

Aiming at the problem that the traditional community dividing algorithms ignore the real-world network characteristics and the accuracy of community dividing is low, this paper proposed a weighted network overlapping community dividing algorithm based on node membership. The algorithm proposed a weighted network model and obtained a weighted network that could describe the real network structure through the model. It defined the core community by the network topology structure, and the core community played an important role in the accuracy of community division. The algorithm calculated the degree of membership between the node and the core community, and compared it with the threshold of membership to expand the core community. According to the optimization idea of the extended modularity, by continuously adjusting the thres-hold of membership until obtained the optimal community structure, it divided the overlapping community. Compared with the existing algorithms on the artificial network dataset and the real-world network dataset, the experimental result verifies that the proposed algorithm can accurately and effectively detect overlapping communities.
