双模网络中的三元闭包:重新定义全局和局部聚类系数

Triadic closure in two-mode networks: Redefining the global and local clustering coefficients

Tore Opsahl

摘要:

由于绝大多数网络测量都是针对单模式网络定义的,因此通常必须将双模式网络投影到单模式网络上才能进行分析。在此转换过程中会出现许多问题,特别是在分析节点联系人之间的联系时。例如,投影随机双模网络的全局和局部聚类系数所获得的值偏离相应的经典单模网络的期望值。此外,无论是局部聚类系数和约束(结构洞)是负相关的节点的双模度。为了克服这些问题,本文提出了重新定义的聚类系数的双模网络。

英文摘要:

As the vast majority of network measures are defined for one-mode networks, two-mode networks often have to be projected onto one-mode networks to be analyzed. A number of issues arise in this transformation process, especially when analyzing ties among nodes' contacts. For example, the values attained by the global and local clustering coefficients on projected random two-mode networks deviate from the expected values in corresponding classical one-mode networks. Moreover, both the local clustering coefficient and constraint (structural holes) are inversely associated to nodes' two-mode degree. To overcome these issues, this paper proposes redefinitions of the clustering coefficients for two-mode networks.
