Description

Graph clustering based on edge betweenness centrality

Usage

1
betweenness.centrality.clustering(g, threshold = -1, normalize = TRUE)

Arguments

g

an instance of the graph class with edgemode “undirected”

threshold

threshold to terminate clustering process

normalize

boolean, when TRUE, the edge betweenness centrality is scaled by 2/((n-1)(n-2)) where n is the number of vertices in g; when FALSE, the edge betweenness centrality is the absolute value

Details

To implement graph clustering based on edge betweenness centrality.

The algorithm is iterative, at each step it computes the edge betweenness centrality and removes the edge with maximum betweenness centrality when it is above the given threshold. When the maximum betweenness centrality falls below the threshold, the algorithm terminates.

See documentation on Clustering algorithms in Boost Graph Library for details.

Value

A list of

no.of.edges

number of remaining edges after removal

edges

remaining edges

edge.betweenness.centrality

betweenness centrality of remaining edges
