摘要:

研究了复杂网络中的lobby指数(简称l指数)作为局部节点中心性度量。在生物网络(酵母相互作用蛋白质-蛋白质网络)和语言网络(Moby Thesaurus II)的情况下,将l-inde与度(局部度量)、介数和特征向量中心性(两个全局度量)进行比较。在这两个网络中,l-指数与介数的相关性较差,但与度和特征向量相关。作为一种局部度量,可以通过使用l-索引来利用,因为与度中心性相比,它携带了更多关于其邻居的信息,实际上与特征向量中心性相比,它需要更少的计算时间。结果表明,l-指数产生更好的结果比度和Eigenvector的措施排名的目的,成为合适的工具来执行这项任务。

英文摘要:

We study the lobby index (l-index for short) as a local node centrality measure for complex networks. The l-inde is compared with degree (a local measure), betweenness and Eigenvector centralities (two global measures) in the case of biological network (Yeast interaction protein-protein network) and a linguistic network (Moby Thesaurus II). In both networks, the l-index has poor correlation with betweenness but correlates with degree and Eigenvector. Being a local measure, one can take advantage by using the l-index because it carries more information about its neighbors when compared with degree centrality, indeed it requires less time to compute when compared with Eigenvector centrality. Results suggests that l-index produces better results than degree and Eigenvector measures for ranking purposes, becoming suitable as a tool to perform this task.
