Abstract: The most popular modularity optimization may fail to identify communities smaller than a scale.A natural density of networks is proposed for describing the degree of interconnectedness of modules.The density modularity function is constructed to evaluate the community structure partitioning based on the natural density.Three cases study proves that the density modularity function can overcome the resolution limit of NG’s modularity.The density modularity has been tested on both artificial networks and classical real-world networks.Computational results demonstrate the effectiveness of the density modularity.

Dynamic identifying protein functional modules based on adaptive density modularity in protein-protein interaction networks
TL;DR: This paper designs a new algorithm ADM (Adaptive Density Modularity) to detect protein functional modules based on adaptive density modularity, and reveals that the performance of ADM algorithm is superior to many state-of-the-art proteinfunctional modules detection techniques in aspect of the accuracy of prediction.
