Kleinberg's CentralityDefinitionSee HITS  Hypertext Induced Topic Selection Kleinberg's hub and authority scores. The authority scores of the vertices are defined as the principal eigenvector of t(A)*A, where A is the adjacency matrix of the graph. The hub scores of the vertices are defined as the principal eigenvector of A*t(A), where A is the adjacency matrix of the graph. Obviously, for undirected matrices the adjacency matrix is symmetric and the two scores are the same. [CSARDI, G. 2006] Requirements
