1. A computer implemented method of scoring a document in a collection comprising:
- determining one or more metrics in a forward direction;
determining one or more backward metrics; and
scoring the document based at least in part on a combination of the metrics;
wherein the one or more backward metrics is determined, at least in part, using a dual graph; and
wherein the dual graph is constructed such that a random walk of a random surfer through a sequence of documents in the collection occurs with equal probability in the dual graph as a corresponding random walk through the same documents'"'"' corresponding dual-graph nodes in reverse order.

Abstract
Scoring a document is disclosed. One or more metrics is determined in a forward direction. One or more backwards metrics is determined. The document is scored based at least in part on a combination of the metrics.

7. A system for scoring a document in a collection comprising:
a processor, configured to; determine one or more metrics in a forward direction; determine one or more backward metrics; and score the document based at least in part on a combination of the metrics; wherein the one or more backward metrics is determined, at least in part, using a dual graph; and wherein the dual graph is constructed such that a random walk of a random surfer through a sequence of documents in the collection occurs with equal probability in the dual graph as a corresponding random walk through the same documents'"'"' corresponding dual-graph nodes in reverse order; and a memory, coupled with the processor, wherein the memory is configured to provide the processor with instructions. - View Dependent Claims (8, 9, 10, 11, 12)
