Clustering Coefficient - Network Average Clustering Coefficient

Network Average Clustering Coefficient

The clustering coefficient for the whole network is given by Watts and Strogatz as the average of the local clustering coefficients of all the vertices :

A graph is considered small-world, if its average clustering coefficient is significantly higher than a random graph constructed on the same vertex set, and if the graph has approximately the same mean-shortest path length as its corresponding random graph.

A generalisation to weighted networks was proposed by Barrat et al. (2004), and a redefinition to bipartite graphs (also called two-mode networks) by Latapy et al. (2008) and Opsahl (2009).

This formula is not, by default, defined for graphs with isolated vertices; see Kaiser, (2008) and Barmpoutis et al. The networks with the largest possible average clustering coefficient are found to have a modular structure, and at the same time, they have the smallest possible average distance among the different nodes.

Famous quotes containing the words network and/or average:

    Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?
    George Eliot [Mary Ann (or Marian)

    Japanese food is very pretty and undoubtedly a suitable cuisine in Japan, which is largely populated by people of below average size. Hostesses hell-bent on serving such food to occidentals would be well advised to supplement it with something more substantial and to keep in mind that almost everybody likes french fries.
    Fran Lebowitz (b. 1975)
