Hi,
does anyone know which algorithm for eigenvector centrality is used and if it is applicable to directed graphs? I cannot find any info on the GitHub page (https://github.com/gephi/gephi/wiki/Eig ... Centrality) and the link to the source code seems to be broken.
Kind regards,
Stefan

Re: Closeness and eigenvector centrality for directed graphs
Thanks. I built a small test model and found the answers: Closeness centrality of node A is based on the shortest path from A to other nodes in the network Eigenvector centrality of node A is based on the importance of nodes (not sure which metric is used for importance) that supply into A, into A's...

Closeness and eigenvector centrality for directed graphs
Hi all, does anyone know how the closeness centrality and eigenvector centrality metrics are calculated for a directed graph? Is it based on "sending" (outdegree) or "receiving" (indegree) connections? The Github page (https://github.com/gephi/gephi/wiki/Closeness-Centrality) does not help here unfo...

Re: All centrality measures showing either 0 or 1.
To be on the safe side: Did you check if the values are actually 0 and 1 or if it is just a question of number formatting? E.g., values could be shown as rounded to the next integer but actually have digits.

[SOLVED] Modularity algorithm
Dear community,
do you know which Modularity algorithm is used for Gephi 0.9.1? I would like to reference the algorithm in a scientific paper.
Kind regards,
Zapata
