Hi,

Computing Betweenness Centrality according to one node does not make sense, since BC of a node n is the number of shortest paths containing n divided by the total number of shortest paths.

Of course you can create your own centrality measure, but it will not be BC anymore.
Or I am missing something maybe...

Cheers.

Hi,

The Betweenness Centrality algorithm implemented in graphstream calculates centrality values for all nodes when we specify :

BetweennessCentrality bc = new BetweennessCentrality();
bc.betweennessCentrality(graph);

I believe the betweenness centrality value for each node is with respect to all other nodes in the graph. Is it possible to just compute betweenness centrality of all nodes in a graph with respect to just one node in graphstream?

For example: If there are 10 nodes having node id from 1 to 10 in a graph. When we calculate betweenness centrality of the entire graph, each node's betweenness value is with respect to every other node in the graph. Instead, I was wondering if there is a provision to compute betweenness value of each node through just one specific node.

Regards
