摘要 集体影响(CI)中心性是众多节点影响力度量方法的最新成果之一。该方法针对局部树状网络,将节点在网络全局连接中的重要性视为其影响力的表征,但其忽视了各节点邻域分布以及局部网络结构健壮程度的差异。故本文在CI中心性的基础上,对局部网络拓扑中目标节点的邻域鲁棒性、l阶邻居的度分布情况以及l阶邻域簇间连接强度等影响因素进行分析、定义和量化,构造出普适性更高的中心性度量方法NewCI,来评价节点影响力。通过在6个真实的复杂网络数据集进行的网络抗毁性实验,表明该中心性度量方法整体表现稳定,且对节点影响力的度量较于CI更为有效和准确。此外,综合考虑有效性、时间复杂度和执行效率,NewCI相比常用的中心性方法,具有更大的优势。

Abstract:Collective influence (CI) centrality is one of the latest achievements in the measurement of node influences, which is designed based on the locally tree-like network and regards the importance of nodes in the global connection as the representation of their influence. However, it ignores the neighborhood distribution of each node and the difference in the robustness of the local network structure. Therefore, based on CI centrality, the influencing factors in the local network topology such as the neighborhood robustness of the target node, the degree distribution of the l-order neighbors and the connection strength between clusters of the l-order neighborhood are analyzed, defined and quantified. Then, a more universal centrality measurement method called NewCI is proposed to evaluate the influence of nodes. The stability of its overall performance and its better effectiveness and accuracy over CI in node influence measurement are demonstrated by the network invulnerability experiments in six real complex network datasets. Considering the effectiveness, time complexity and execution efficiency, NewCI also has a greater advantage than other commonly used centrality method.
