In other words, instead of looking for edges that are more likely to be in a community, it looks for edges to remove in between communities (Girvan and Newman, 2002). Using the bipartite graph we made, we used a Python library called igraph and found 23 communities. http://duoduokou.com/python/30746842762691031508.html dvd wmp 再生できない
