摘要
为了分析社会网络中影响结构洞节点测量的因素,首先阐述了现有的7种定量衡量结构洞节点的方法,然后构建了4组12个具有不同结构特征的模拟网络。在模拟网络上对结构洞节点的度量指标进行深入而全面的分析和比较。同时,在人人网社会网络上进行实证分析。实验结果表明,这7种度量指标均难以准确度量结构洞节点,不同指标间存在着一定的相关性。在7种度量指标中,介数中心性能相对取得较好的效果。
In order to analyze different factors that affected structural holes measurement in social networks, seven exist- ing methods to measure structural hole nodes were analyzed. Four groups of 12 simulated networks were built. Measure indexes for structural hole nodes were deeply and overall analyzed and compared in the simulated network, which were testified and analyzed in social network of Renren websites. The experimental results showed that seven existing meth- ods perform poorly on identifying the structural hole nodes and some methods were highly correlated. Among these sev- en methods, betweenness centrality was relatively more effective.
