“…There are several techniques that have been developed for detecting communities in networks. A number of them are based on modularity-optimization, hierarchical clustering, label propagation, region density, core clustering [33], game theory, information theory (infomap) [34,35,36,37,38], and biological evolution (genetics) [39,40,41]. Metrics such as the modularity score [20,42,40], Normalized Mutual Information index (NMI) [43,44], and Jaccard Index [43] are used to compare the quality of communities obtained with different approaches.…”
