动态属性复杂网络中社团的一种刻画方法

A Method for Characterizing Communities in Dynamic Attributed Complex Networks

Günce Keziban Orman, Vincent Labatut, Marc Plantevit, Jean-François Boulicaut

摘要:

人们已经提出了许多方法来检测社区,不仅在平原,而且在属性,有向甚至动态复杂网络。在其最简单的形式中,社区结构采取节点集的分区的形式。从建模的角度来看,要有一定的效用,这种划分必须相对于所研究的系统的属性来表征。然而,如果大多数现有的作品集中在定义的方法来检测社区,只有很少的尝试来解决这个解释问题。此外,现有的方法要么在它们处理的数据类型方面受到限制,要么在它们输出的结果的性质方面受到限制。在这项工作中,我们提出了一种方法来有效地支持这样的表征任务。我们首先定义了一个基于序列的网络表示,结合时间信息,拓扑措施,节点属性。然后,我们描述了如何识别该数据集的最新序列模式,并使用它们来表征社区。我们还展示了如何检测社区中的异常行为,并突出异常值。最后,作为一个例子,我们将我们的方法应用于科学合作网络。

英文摘要:

Many methods have been proposed to detect communities, not only in plain, but also in attributed, directed or even dynamic complex networks. In its simplest form, a community structure takes the form of a partition of the node set. From the modeling point of view, to be of some utility, this partition must then be characterized relatively to the properties of the studied system. However, if most of the existing works focus on defining methods for the detection of communities, only very few try to tackle this interpretation problem. Moreover, the existing approaches are limited either in the type of data they handle, or by the nature of the results they output. In this work, we propose a method to efficiently support such a characterization task. We first define a sequence-based representation of networks, combining temporal information, topological measures, and nodal attributes. We then describe how to identify the most emerging sequential patterns of this dataset, and use them to characterize the communities. We also show how to detect unusual behavior in a community, and highlight outliers. Finally, as an illustration, we apply our method to a network of scientific collaborations.
