Patent ID: 8244664

Claim:
A computer-implemented method, comprising: receiving a subject graph, wherein the subject graph includes two or more subject nodes, and wherein each subject node corresponds to a subject; and determining an objective influence measure based on the subject graph for each first subject node of the subject graph, wherein the determination is based at least on part on a function of inward scores and outward scores, wherein inward scores are computed from one or more paths leading to the first subject of a length of at least one, and wherein outward scores are computed from one or more paths leading from the first subject of a length of at least one, wherein the computation of objective influence measure for the first subject node performed using the inward scores and the outward scores is a minimum-spend eigenvector centrality of the first subject node, wherein the minimum-spend eigenvector centrality is determined by an iterative computation of eigenvector centrality.
