It is meant to test the level of clustering in a network. Have a look at Newman and Girvan’s paper where they propose the edge betweenness method, and defined a quality measure, Q. Also you can look at Krackhardt’s work on ties inside versus ties outside.

Best,
Tore

I want to use this method to evaluate clustering quality, I mean I would like to know the quality of clustering results, is it appropriate?

The clustering measure varies from 0 to 1. In a directed network, this simply imples that no two-path is closed by a third tie from the first to the third node on the path.

I have a directed NW and clutering_w is giving me 0. As I understood from your paper, you included transitivity in this extended generalized metric.

Any suggestions?

Do you have a JAVA version of the algorithm?

Thanks
