Properties of ground-truth communities sorted by edge density.

CR stands for Conductance Ratio. High values of clustering, density and separability and low values of CR, conductance and Cohesiveness indicate good communities.CR代表电导比（Conductance Ratio）。较高的聚类、密度与可分离性取值，搭配较低的CR、电导（conductance）以及凝聚度（Cohesiveness）取值，意味着对应的社区结构质量优异。
