- Abstract:
-
The density-based graph clustering algorithm has been widely used in community detection. However, because it identifies a community by searching a partially dense subgraph in the network, many nodes do not constitute a dense subgraph and are therefore difficult to cluster. In this paper, we present a soft clustering algorithm based on dense subgraphs (BDSG) for detecting communities in complex networks. First, we propose a method for detecting the central communities. Next, we define the degree of community attribution of a node, and put forward a core community extended strategy. Finally, we obtain the clustering results of a network. Compared with the clique percolation method (CPM), k-dense algorithms from Zachary’s Karate Club, the dolphin social network, the American college football network, the email network, and the collaboration network, BDSG shows considerably better performance with respect to modularity and time efficiency. In addition, the proposed core community extended strategy may improve the effectiveness of the clustering-methods-based density, such as that in CPM, k-dense algorithms, and others.
