图相似性的建模与度量:中心距离的情况

Modeling and Measuring Graph Similarity: The Case for Centrality Distance

Matthieu Roy, Stefan Schmid, Gilles Trédan

摘要:

复杂网络拓扑结构的研究已经吸引了研究者们几十年的时间,今天我们已经对许多不同的复杂网络的类型和重现特性有了相当好的了解。然而,令人惊讶的是,今天对比较复杂图形的模型知之甚少,并定量地测量它们的相似性。本文提出了一种复杂网络的自然相似性度量:中心性距离,即两个图之间关于给定节点中心性的差异。中心距离允许考虑网络中不同节点的特定角色,并有许多有趣的应用。作为一个案例研究,我们考虑了更详细的接近中心,并表明,接近中心距离可以有效地区分随机生成的和实际的两个动态社交网络的进化路径。

英文摘要:

The study of the topological structure of complex networks has fascinated researchers for several decades, and today we have a fairly good understanding of the types and reoccurring characteristics of many different complex networks. However, surprisingly little is known today about models to compare complex graphs, and quantitatively measure their similarity. This paper proposes a natural similarity measure for complex networks: centrality distance, the difference between two graphs with respect to a given node centrality. Centrality distances allow to take into account the specific roles of the different nodes in the network, and have many interesting applications. As a case study, we consider the closeness centrality in more detail, and show that closeness centrality distance can be used to effectively distinguish between randomly generated and actual evolutionary paths of two dynamic social networks.
