基于模糊局部维数的复杂网络影响节点识别

Identifying influential nodes based on fuzzy local dimension in complex networks

Tao Wen, Wen Jiang

摘要:

如何识别复杂网络中的影响节点是复杂网络研究的一个重要方面。本文提出了一种新的模糊局部维数(FLD)来对复杂网络中的影响节点进行排序,其中具有高模糊局部维数的节点具有高的影响能力。该方法利用模糊集的方法,重点研究了距离中心节点的距离对中心节点局部维数的影响,从而改变影响能力。为了证明该方法的有效性和准确性,本文应用了四个现实世界的网络。同时,利用易受感染(SI)模型模拟FLD等中心性度量的传播过程,并利用Kendall的tau系数描述中心性度量得到的影响节点与SI模型测量结果之间的相关性。从排序列表和仿真结果来看,该方法对影响节点的排序是有效和准确的。

英文摘要:

How to identify influential nodes in complex networks is an important aspect in the study of complex network. In this paper, a novel fuzzy local dimension (FLD) is proposed to rank the influential nodes in complex networks, where a node with high fuzzy local dimension has high influential ability. This proposed method focuses on the influence of the distance from the center node on the local dimension of center node by fuzzy set, resulting in a change in influential ability. In order to show this proposed method's effectiveness and accuracy, four real-world networks are applied in this paper. Meanwhile, Susceptible-Infected (SI) is used to simulate the spreading process by FLD and other centrality measures, and Kendall's tau coefficient is used to describe the correlation between the influential nodes obtained by centrality and the results measured by SI model. Observing from the ranking lists and simulated results, this method is effective and accurate to rank the influential nodes.
