WebCommunity Detection using Girvan-Newman. #. This example shows the detection of communities in the Zachary Karate Club dataset using the Girvan-Newman method. We plot the change in modularity as important edges are removed. Graph is coloured and plotted based on community detection when number of iterations are 1 and 4 respectively. Webity. We then propose the weighted modularity formulation and prove that the metric does not su er from resolution limitation. We then ﬁnally present a community detection approach based on the maximization of the weighted modularity metric. 2.1. Traditional Modularity The idea of modularity was originally proposed by Newman
