一种改进的有影响力用户识别的复合中心性度量

A Composite Centrality Measure for Improved Identification of Influential Users

Ahmad Zareie, Amir Sheikhahmadi, Rizos Sakellariou

摘要:

近年来,识别社交网络用户的传播能力并根据其影响力对其进行排名的问题引起了人们的广泛关注;为此目的,已经提出了不同的方法。这些方法中的大多数依赖于图中节点及其邻居的拓扑位置,以提供估计用户传播能力的度量。其中最著名的测度之一是k-shell,在此基础上又提出了其他测度,但由于同一k-shell指标可能被分配给不同度的节点,因此该测度的准确性较低。本文试图改进这一点,提出了一种复合中心性度量,它结合了节点的度和k壳指数。在各种真实和人工网络上的实验结果和评估表明,该措施优于其他国家的最先进的措施的单调性和准确性。

英文摘要:

In recent years, the problem of identifying the spreading ability and ranking social network users according to their influence has attracted a lot of attention; different approaches have been proposed for this purpose. Most of these approaches rely on the topological location of nodes and their neighbours in the graph to provide a measure that estimates the spreading ability of users. One of the most well-known measures is k-shell; additional measures have been proposed based on it. However, as the same k-shell index may be assigned to nodes with different degrees, this measure suffers from low accuracy. This paper is trying to improve this by proposing a composite centrality measure in that it combines both the degree and k-shell index of nodes. Experimental results and evaluations of the proposed measure on various real and artificial networks show that the proposed measure outperforms other state-of-the-art measures regarding monotonicity and accuracy.
