图中的社区检测

Community detection in graphs

Santo Fortunato

摘要:

现代网络科学为我们理解复杂系统带来了重大进展。表示真实系统的图的最相关的特征之一是社区结构,或聚类,即。e.顶点在簇中的组织,许多边连接同一簇的顶点,相对较少的边连接不同簇的顶点。这样的集群,或社区,可以被认为是图中相当独立的部分,扮演着类似的角色,如,e。例如,在一个实施例中,人体内的组织或器官。检测社区在社会学、生物学和计算机科学中非常重要,这些学科通常将系统表示为图形。这个问题很难解决,尽管过去几年来,大量跨学科的科学家在这个问题上付出了巨大的努力,但仍然没有得到令人满意的解决。我们将尝试对这个主题进行全面的阐述,从问题的主要元素的定义,到大多数方法的介绍,特别关注统计物理学家设计的技术,从关键问题的讨论,如聚类的意义,以及如何测试和比较方法,到描述实际网络的应用。

英文摘要:

The modern science of networks has brought significant advances to our understanding of complex systems. One of the most relevant features of graphs representing real systems is community structure, or clustering, i. e. the organization of vertices in clusters, with many edges joining vertices of the same cluster and comparatively few edges joining vertices of different clusters. Such clusters, or communities, can be considered as fairly independent compartments of a graph, playing a similar role like, e. g., the tissues or the organs in the human body. Detecting communities is of great importance in sociology, biology and computer science, disciplines where systems are often represented as graphs. This problem is very hard and not yet satisfactorily solved, despite the huge effort of a large interdisciplinary community of scientists working on it over the past few years. We will attempt a thorough exposition of the topic, from the definition of the main elements of the problem, to the presentation of most methods developed, with a special focus on techniques designed by statistical physicists, from the discussion of crucial issues like the significance of clustering and how methods should be tested and compared against each other, to the description of applications to real networks.
