使用多标准方法评估社区分区

Using multiple-criteria methods to evaluate community partitions

Remy Cazabet, Rathachai Chawuthai, Hideaki Takeda

摘要:

社区发现是复杂网络中研究最多的问题之一。尽管到目前为止已经提出了数百种方法,但对于什么是好的社区仍然没有一个普遍接受的正式定义。因此,这些算法产生的解决方案的质量的评价和比较的问题仍然是一个悬而未决的问题,尽管不断取得进展的主题。在这篇文章中,我们将探讨如何使用多标准评估可以解决一些社区评估的现有问题,特别是多个同等相关的解决方案的不同粒度的问题。在探索了几种方法之后,我们引入了一个新的质量函数,称为MDensity,并提出了一种方法,该方法可以与广泛使用的社区发现度量,模块化,和精度/召回方法,无处不在的信息检索。

英文摘要:

Community detection is one of the most studied problems on complex networks. Although hundreds of methods have been proposed so far, there is still no universally accepted formal definition of what is a good community. As a consequence, the problem of the evaluation and the comparison of the quality of the solutions produced by these algorithms is still an open question, despite constant progress on the topic. In this article, we investigate how using a multi-criteria evaluation can solve some of the existing problems of community evaluation, in particular the question of multiple equally-relevant solutions of different granularity. After exploring several approaches, we introduce a new quality function, called MDensity, and propose a method that can be related both to a widely used community detection metric, the Modularity, and to the Precision/Recall approach, ubiquitous in information retrieval.
