βNodeRank:一种对社交网络节点重要性评估的方法

βNode Rank-based node importance evaluation method for social networks

现有基于Page Rank算法的社交网络节点重要性评估方法聚焦在社交网络节点出入度、边权值上,忽略了社交网络节点所在网络结构上位置差异的因素。分析现有基于Page Rank算法的方法对社交网络节点重要性评估缺陷,提出改进评估方法βNode Rank。通过原理分析和实验分析对改进方法的优势进行比较,结果表明改进方法在社交网络节点重要性评估上更加合理。

The available PageRank algorithm based node importance evaluation methods for social network mainly focus on the node access degree and edge weight of social network,but ignores the effect of location difference of the social network node on network structure.An improved node importance evaluation method for social network is proposed on the basis ofβNodeRank by analyzing the node importance evaluation defects of social network based on the available PageRank algorithm.The advantage of this improved method is analyzed with principle analysis and experiment analysis,and the results show that the method is reasonable for node importance evaluation of social network.
