WebBetweenness Centrality is a way of detecting the amount of influence a node has over the flow of information in a network. It is typically used to find nodes that serve as a bridge from one part of a graph to another. The Betweenness Centrality algorithm first calculates the shortest path between every pair of nodes in a connected graph.
