Re: BetweennessCentrality

[Antoine Dutot <antoine.dutot AT gmail.com>]

Hi Ann,

After the algorithm execution, each node contains a "Cb" attribute for the betweeness centrality value:

for(Node node: graph) {

    System.out.println("Centrality of "+node.getId()+" = "+node.getNumber("Cb"));

}

You can also display these values in the graph viewer:

graph.display();

for(Node node: graph) {

    node.setAttribute("ui.label", String.format("%f", node.getNumber("Cb")));

}

Hope this helps,

Antoine

Hi, I downloaded the greaphstream tool and I would like to calculate he betweenness centrality of the graph.  I used  betweennessCentrality to

Compute the betweenness centrality on the given graph for each node.

 

could you please  let me know what command I need to use to print the centrality values of the  nodes.

 

Thanks,

Ann
