WebThe eigenvector centrality has an interesting, circular definition: nodes are considered more important if they themselves are connected to important nodes. For this and many other centrality measures, we also don’t care about the scale of these importance scores - for instance, scores of $[2, 1]$ would be interpreted the same as \([20, 10 ... 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. [7] [8]
