Thanks for the feedback. Zhang et al’s paper is interesting, and is commented on in the updated version of the paper that this blog post is based on. The main difference between their measure and the above measure is that they use 4-cycles, and therefore only measure two primary nodes tendency to for, repeated ties between themselves. The purpose of the above measure is to measure closure among three primary nodes (i.e., among a group).

Have you seen the following publications:

zhang et al (2008) Clustering coefficient and community structure of bipartite networks. Physica A

and cited in

Beguerisse Díaz et al (2010) for popularity in bipartite networks. Chaos. 20, 043101

May ask your opinion on these and the difference between them and the above?

Thank you for the reference. In an updated paper that’s already under revision, that reference is well incorporated.

Best,
