模糊重叠社区质量评价

Fuzzy Overlapping Community Quality Metrics

Mingming Chen, Boleslaw K. Szymanski

摘要:

模块性被广泛用于有效地度量由社区发现算法发现的不相交社区结构的强度。提出了几种模块度的重叠扩展来度量重叠社区结构的质量。然而,所有这些扩展的不同之处仅在于它们定义归属系数和归属函数的方式。然而,缺乏对不同扩展的系统比较。为了填补这一空白,我们概述了重叠的模块化扩展,并将其推广到一个统一的定义,使不同的归属系数和归属函数的应用程序,以选择最好的。此外,我们扩展了本地化的模块化,模块化密度,和八个本地社区质量指标,使他们的使用重叠的社区。在大量的真实网络和合成网络上使用重叠扩展模块性、重叠模块性密度和局部度量的实验结果表明,当使用两个节点的归属系数的乘积作为归属函数时,获得了最好的结果。此外,研究结果可用于指导研究人员在测量重叠社区结构的质量时采用哪些指标。

英文摘要:

Modularity is widely used to effectively measure the strength of the disjoint community structure found by community detection algorithms. Several overlapping extensions of modularity were proposed to measure the quality of overlapping community structure. However, all these extensions differ just in the way they define the belonging coefficient and belonging function. Yet, there is lack of systematic comparison of different extensions. To fill this gap, we overview overlapping extensions of modularity and generalize them with a uniform definition enabling application of different belonging coefficients and belonging functions to select the best. In addition, we extend localized modularity, modularity density, and eight local community quality metrics to enable their usages for overlapping communities. The experimental results on a large number of real networks and synthetic networks using overlapping extensions of modularity, overlapping modularity density, and local metrics show that the best results are obtained when the product of the belonging coefficients of two nodes is used as the belonging function. Moreover, the results may be used to guide researchers on which metrics to adopt when measuring the quality of overlapping community structure.
