加权网络节点中心性的极值分析

Extrema Analysis of Node Centrality in Weighted Networks

Roger S. Passos, Douglas O. Cardoso

摘要:

网络科学的一个非常有趣的问题是评估给定网络的复杂程度。换句话说,这样的网络在多大程度上偏离了可以用来描述它的任何一般模式。在其他选择中,这些模式可以根据节点或边属性定义,作为中心性的各种模式之一。虽然有为加权图定义的中心性指数,但关于这个主题的讨论远未结束,特别是因为边权重在这方面的影响不仅在形式上而且在强度上都不同,这是迄今为止仍处于起步阶段的方法。对于前面提到的复杂性评估,情况更加严重:据我们所知,从加权图的中心性的角度来看,这在文献中从未得到过解决。本文详细介绍了一个丰富多彩的时尚一个健全的方法,涵盖这两个主题,以及实验证实其实用性和未来的趋势,在这方面。

英文摘要:

A very interesting matter of Network Science is assessing how complex a given network is. In other words, by how much does such a network departs from any general patterns which could be evoked for its description. Among other choices, these patterns can be defined in terms of node or edge properties, as one of the various modes of centrality. Although there are centrality indexes defined for weighted graphs, the discussions on this subject are far from over, especially because the influence of edge weights in this regard can vary not only in form but also in intensity, a still incipient approach so far. For the aforementioned complexity evaluation, the situation is even more acute: to the best of our knowledge, this was never addressed in the literature, from the standpoint of centrality in weighted graphs. This paper details in a colorful fashion a sound methodology covering both topics, as well as experiments confirming its practical applicability and future trends in this context.
