加权有向网络的PageRank中心性和算法及其在世界投入产出表中的应用

PageRank centrality and algorithms for weighted, directed networks with applications to World Input-Output Tables

Panpan Zhang, Tiandong Wang, Jun Yan

摘要:

PageRank(PR)是一种评估网络中节点相对重要性的基本工具。在本文中,我们提出了一种措施,加权PageRank(WPR),从经典的PR扩展的加权,有向网络与可能的非均匀的节点特定的信息是依赖或独立的网络结构。引入了利用节点度和强度的调整参数。本文提出了一种基于R程序的大规模网络加权比计算方法。我们已经在广泛使用的模拟网络模型上测试了所提出的WPR,发现它优于文献中的其他竞争措施。通过将所提出的WPR应用于从世界投入产出表生成的真实网络数据,我们已经看到了与全球经济趋势一致的结果,这使得它成为分析中的首选措施。

英文摘要:

PageRank (PR) is a fundamental tool for assessing the relative importance of the nodes in a network. In this paper, we propose a measure, weighted PageRank (WPR), extended from the classical PR for weighted, directed networks with possible non-uniform node-specific information that is dependent or independent of network structure. A tuning parameter leveraging node degree and strength is introduced. An efficient algorithm based on R program has been developed for computing WPR in large-scale networks. We have tested the proposed WPR on widely used simulated network models, and found it outperformed other competing measures in the literature. By applying the proposed WPR to the real network data generated from World Input-Output Tables, we have seen the results that are consistent with the global economic trends, which renders it a preferred measure in the analysis.
