Abstract: A community division quality evaluation method and system based on average mutual information. A community division quality evaluation method based on average mutual information is added on to the classic GN community division system. First, by means of calculating the average mutual information value for each community division, the optimal community division having the highest average mutual information value is selected. Then, the information entropies of the community structures before and after the optimal community division are respectively calculated, whence the optimized community structure is determined. Immediately afterwards, all nodes of the optimized community structure are traversed to find nodes having the same number of links to multiple communities. Finally, the total information entropies in the network when said nodes are placed in different communities are respectively calculated, and the community structure having the minimum total information entropy value, which is the optimal community structure, is output. The accuracy of community division results is thus effectively raised.
