Kleinberg's Centrality


Definition


See 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.
