1. A method of ranking the relevance of a node in a linked set of nodes, comprising:
- determining an authority-like weight for said node using a non-compound, non-normalized Forward operator; and
determining a hub-like weight for said node using a non-compound, non-normalized Backward operator, said steps of determining being mathematically decoupled.

Abstract
A method, system, and computer program product for hypertext link analysis that includes independently employing non-normalized backward and forward operators to obtain two independent weights for each document in a hypertext-linked graph, for subsequent ranking and analysis.
