Study on Algorithm of Community Detection Based on Information Entropy

There are some faults of present community detection algorithm,which is based on the in degree,out degree and betweenness of nodes,we presented a algorithm based on Entropy to detect community structure.A community includes many information and it's Entropy.Members of a community have some common gains or interests,we think that if a member want to join a community,it can't make the entropy of the community exceed a threshold,otherwise it can't be the member of a exist community.Our experiments show the processing and the efficiency of our algorithms.
