识别复杂网络中最具影响力的节点为理解传播动态和确保更有效的信息传播提供了坚实的基础。由于异构度分布，我们观察到，目前的中心性措施相关的节点排名的结果。本文介绍了全能节点的概念，它的行为就像全能球员具有良好的综合性能指标。然后，一个全面的距离量化节点的影响。实验结果表明，所提出的全方位距离可以作为一个更准确，稳定的指标的影响力节点。(C)2012爱思唯尔有限公司版权所有。
Identifying the most influential nodes in complex networks provides a strong basis for understanding spreading dynamics and ensuring more efficient spread of information. Due to the heterogeneous degree distribution, we observe that current centrality measures are correlated in their results of nodes ranking. This paper introduces the concept of all-around nodes, which act like all-around players with good performance in combined metrics. Then, an all-around distance is presented for quantifying the influence of nodes. The experimental results of susceptible-infectious-recovered (SIR) dynamics suggest that the proposed all-around distance can act as a more accurate, stable indicator of influential nodes.
