Abstract
A system and method for ranking hyperlinked documents, such as web pages, is provided wherein a stochastic backoff process is used to rank those hyperlinked documents. In more detail, the stochastic process is derived from a random walk through the pages of the web. First, a directed graph may be generated from a crawl wherein the nodes are documents in the crawl and a directed edge from one node A to another node B indicates the presence of a hyperlink from the corresponding document docA to document docB. Using a stochastic backoff process on this graph, a weight between 0 and 1 is assigned to each document so that the documents may be ranked according to the weights.
