duplicate edges and betweenness

Nov 20, 2013 at 9:32 PM
Hi, I have a dataset with many duplicate edges. Do the centrality measures (especially betweenness) take into account all of the duplicate edges in calculations, or do they just consider the duplicates as a single edge? I have just started with nodexl so apologise if this is a very simple question.

The calculations for betweenness centrality, closeness centrality, eigenvector centrality and PageRank ignore duplicate edges. You can have five edges between vertices A and B and the results for these calculations will be the same as if you had one edge between A and B.

(Don't worry about that being a simple question. I'm the NodeXL programmer, and I had to go look it up.)
