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 ... WebApr 11, 2024 · In this study, considering the weight and direction of edges, the betweenness centrality of nodes was calculated. Compared with undirected or unweighted networks, this method can be used to demonstrate the importance of the betweenness centrality of nodes more accurately. Calculating the betweenness centrality of all nodes …
WebThe current-flow betweenness of a vertex v is defined as the amount of current that flows through v in this setup, averaged over all vertex pairs s and t. The current-flow betweenness of a vertex v is the average of the current flow over all source–target pairs: where n (n − 1)/2 is a normalizing constant, and I v(st) is the current flow ...

WebA class of centrality measures called betweenness centralities reflects degree of participation of edges or nodes in communication between different parts of the network. The original shortest-path betweenness centrality is based on counting shortest paths which go through a node or an edge.
