复杂网络中心性测度之间的相关性

Correlations among centrality measures in complex networks

Chang-Yong Lee

摘要:

在本文中,我们实证研究了四个中心性措施之间的相关性,起源于社会科学,各种复杂网络。对于每个网络,我们计算的中心性措施,从偏相关性,以及措施之间的相关系数估计。我们发现,度和介数中心性是高度相关的,此外,介数遵循幂律分布,无论网络的类型。这一特点是进一步检查的介数的条件概率分布,给定的程度。条件分布也表现出幂律行为独立的程度,解释部分,如果不是全部,幂律分布的介数的起源。对随机网络的类似分析表明,这些特征在随机网络中没有发现。

英文摘要:

In this paper, we empirically investigate correlations among four centrality measures, originated from the social science, of various complex networks. For each network, we compute the centrality measures, from which the partial correlation as well as the correlation coefficient among measures is estimated. We uncover that the degree and the betweenness centrality are highly correlated; furthermore, the betweenness follows a power-law distribution irrespective of the type of networks. This characteristic is further examined in terms of the conditional probability distribution of the betweenness, given the degree. The conditional distribution also exhibits a power-law behavior independent of the degree which explains partially, if not whole, the origin of the power-law distribution of the betweenness. A similar analysis on the random network reveals that these characteristics are not found in the random network.
