正负链接网络中的社区发现

Community detection in networks with positive and negative links

V. A. Traag, Jeroen Bruggeman

摘要:

准确地检测复杂网络中的社区是进一步分析网络特征和动态特性之前的主要挑战。到目前为止,社区检测只考虑了正价值的链接,而许多实际网络也具有负链接。我们扩展了现有的波茨模型,将负链接,以及在一个类似的方法,在社会平衡理论中处理的符号图的聚类,但更一般。为了说明我们的方法,我们将其应用于国际联盟和争端网络。使用1993- 2001年的数据,结果表明,世界可以分为六个类似于亨廷顿文明的权力集团,除了一些值得注意的例外。

英文摘要:

Detecting communities in complex networks accurately is a prime challenge, preceding further analyses of network characteristics and dynamics. Until now, community detection took into account only positively valued links, while many actual networks also feature negative links. We extend an existing Potts model to incorporate negative links as well, resulting in a method similar to the clustering of signed graphs, as dealt with in social balance theory, but more general. To illustrate our method, we applied it to a network of international alliances and disputes. Using data from 1993--2001, it turns out that the world can be divided into six power blocs similar to Huntington's civilizations, with some notable exceptions.
