Kendall’s tau between ranking scores provided by different methods and the real spreading abilities.

Here we focus on the ranks of the top- ( = 20 and 50) nodes with maximal out-degrees. We abbreviate ClusterRank, LeaderRank, PageRank and Out-degree centrality by CR, LR, PR and DR, respectively.

本研究聚焦于出度（out-degree）最大的前20和前50节点的排名。我们将聚类排名（ClusterRank）、领导者排名（LeaderRank）、网页排名（PageRank）与出度中心性（Out-degree centrality）分别缩写为CR、LR、PR及DR。
