Abstract
Exemplary methods for assigning relative rank values to a plurality of linked documents are provided. In one embodiment, the method comprises constructing or modeling a nodal network according to a connectivity graph of a linked database and determining conductance of inter-nodal links based on a link structure of the nodal network and rank values of end-nodes. The method may further comprise computing rank values of nodes in the nodal network through an iterative process, and obtaining quality scores for documents from the rank values of the nodes. The method may also include obtaining the quality scores for groups of documents.
