Flow betweenness centrality
WebDefinition. Freeman et al. define the raw or unnormalized flow betweenness of a vertex, v ∈ V (G) as: where f (i, j, G) is the maximum flow from i to j within G (under the assumption … WebCurrent-flow Centrality. Typically, geodesic (shortest) paths are considered in the definition of both closeness and betweenness. These are optimal paths with the lowest number of edges or, if the graph is weighted, paths with the smallest sum of edge weights. There are two drawbacks of this approach:

WebAbstract. We consider variations of two well-known centrality measures, betweenness and closeness, with a different model of information spread. Rather than along shortest paths only, it is assumed that information spreads efficiently like an electrical current. We prove that the current-flow variant of closeness centrality is identical with ...
WebCompute current-flow betweenness centrality for edges using subsets of nodes. Current-flow betweenness centrality uses an electrical current model for information spreading in contrast to betweenness centrality which uses shortest paths.
