Webty (Q) as Fine-tuned Q while the one based on Modularity Density (Qds) is referred to as Fine-tuned Qds. Finally, we evaluate the greedy algorithm of modularity max-imization (denoted as Greedy Q), Fine-tuned Q, and Fine-tuned Qds by using seven community quality metrics based on ground truth communities. These evaluations WebApr 27, 2015 · A precise definition of the modularity from wikipedia: Modularity is the fraction of the edges that fall within the given groups minus the expected such fraction if edges were distributed at random. The value of the modularity lies in the range [−1/2,1). It is positive if the number of edges within groups exceeds the number expected on the ...
