复杂网络的中心化

Centralization of Complex Networks

复杂网络的中心化有助于发现复杂网络中的重要节点,因而具有重要的应用价值。本文系统介绍了复杂网络中常用的几种中心化指标,通过定量比较指出了不同中心化指标的特点及应用场合;同时本文还介绍了针对社会网络、病毒传播网络、交通网络和恐怖分子网络等几种不同类型的复杂网络的中心化过程,指出了复杂网络的中心化的实际意义。

Centralization of complex networks, which can help us find important nodes in complex networks, is of great practical value in many applications. In this paper, the characteristics of several common centrality indices are analyzed and compared to point out the situations in which these indices can be applied. At the same time, the centralization process of several typical complex networks, such as social networks, epidemic spreading networks, traffic networks and terrorist networks, are introduced to point out the practical significance of centralization of complex networks.
