基于相关性的社区发现

Correlation-Based Community Detection

Zheng Chen, Zengyou He, Hao Liang, Can Zhao, Yan Liu

摘要:

从复杂网络中挖掘社区结构是一个跨领域的重要问题。许多现有的社区发现方法通过优化社区评价函数来检测社区。然而,这些函数中的大多数甚至在随机图上具有很高的值,并且可能无法检测大规模网络中的小社区(所谓的分辨率限制问题)。在本文中,我们引入了两个新的节点为中心的社区评价功能,通过相关性分析与社区发现。我们将进一步表明,相关性分析可以提供一个新的理论框架,它统一了一些现有的评价函数的背景下,基于相关性的优化问题。在此框架下,我们可以通过选择合适的相关函数来缓解分辨率极限问题并消除随机波动的影响。此外,我们将关联规则挖掘中的三个关键属性引入到社区发现中,以帮助我们选择合适的相关函数。基于我们引入的相关函数,我们提出了一个社区发现算法CBCD。我们提出的算法优于现有的国家的最先进的算法在合成基准网络和现实世界的网络。

英文摘要:

Mining community structures from the complex network is an important problem across a variety of fields. Many existing community detection methods detect communities through optimizing a community evaluation function. However, most of these functions even have high values on random graphs and may fail to detect small communities in the large-scale network (the so-called resolution limit problem). In this paper, we introduce two novel node-centric community evaluation functions by connecting correlation analysis with community detection. We will further show that the correlation analysis can provide a novel theoretical framework which unifies some existing evaluation functions in the context of a correlation-based optimization problem. In this framework, we can mitigate the resolution limit problem and eliminate the influence of random fluctuations by selecting the right correlation function. Furthermore, we introduce three key properties used in mining association rule into the context of community detection to help us choose the appropriate correlation function. Based on our introduced correlation functions, we propose a community detection algorithm called CBCD. Our proposed algorithm outperforms existing state-of-the-art algorithms on both synthetic benchmark networks and real-world networks.
