基于团合并的网络社区检测

Detecting Communities in Networks by Merging Cliques

Bowen Yan, Steve Gregory

摘要:

已经提出了许多算法来检测网络中的不相交社区(相对密集连接的子图)。一种流行的技术是优化模块化,这是一种衡量分区质量的标准,即内部和社区间边缘的数量。最大化模块度的贪婪近似算法可以非常快速和有效。我们提出了一个新的算法,开始检测不相交的集团,然后合并这些优化模块化。我们表明,这比其他类似的算法在模块化和执行速度方面表现更好。

英文摘要:

Many algorithms have been proposed for detecting disjoint communities (relatively densely connected subgraphs) in networks. One popular technique is to optimize modularity, a measure of the quality of a partition in terms of the number of intracommunity and intercommunity edges. Greedy approximate algorithms for maximizing modularity can be very fast and effective. We propose a new algorithm that starts by detecting disjoint cliques and then merges these to optimize modularity. We show that this performs better than other similar algorithms in terms of both modularity and execution speed.
