WebEigenvector centrality is a measure of the influence a node has on a network. If a node is pointed to by many nodes (which also have high eigenvector centrality) then that node will have high eigenvector centrality. [6] The earliest use of eigenvector centrality is by Edmund Landau in an 1895 paper on scoring chess tournaments.

It is a generalization of the eigenvector centrality. The Katz centrality for node i is x i = α ∑ j A i j x j + β, where A is the adjacency matrix of graph G with eigenvalues λ. The parameter β controls the initial centrality and α < 1 λ max. tali vald

WebMar 7, 2011 · Eigenvector centrality is one method of computing the "centrality", or approximate importance, of each node in a graph. The assumption is that each node's centrality is the sum of the centrality values of the nodes that it is connected to. The nodes are drawn with a radius proportional to their centrality.
