Graph betweenness centrality
WebThe Betweenness Centrality algorithm first calculates the shortest path between every pair of nodes in a connected graph. Each node receives a score based on the number of these shortest paths that pass through the node. The more shortest paths that a node lies on, the higher its score.

WebFeb 4, 2024 · Betweenness Centrality is a way of detecting the amount of influence a node has over the flow of information in a graph. It is often used to find nodes that serve as a bridge from one part of a graph to another. In the following example, Alice is the main connection in the graph. If Alice is removed, all connections in the graph would be cut ...
