Abstract: | Identification of communities in a complex network is one of the important problems in data mining of network data.The bacterial colony chemotaxis(BCC)strategy with fuzzy C-means(FCM)algorithm was used to maximize the modularity of a network.In the new algorithm,the initial cluster center of FCM algorithm was obtained by BCC algorithm.Then,the FCM algorithm was used for detecting communities in a complex network.The proposed algorithm outperformed most the existing methods in the literature as regards the optimal modularity found.Experimental results for real-word networks confirmed the feasibility and effectiveness of the proposed algorithm. |
