1. A system for path-based ranking of unvisited Web pages for WWW crawler, comprising: a storage unit which stores all paths leading to visited web pages containing content relevant to a search as a good-path set and all paths leading to unvisited web pages as a partial-path set; a classifier and a labeler which classifies all the visited web pages and labels each web page with the labels of a class or classes it belongs to; a statistic modeler which trains a statistic model for generalizing common patterns among all ones of the good-path set; and an evaluator which evaluates the partial-path set with the statistic model to determine a similarity between the partial-path set and all ones of the good-path set and ranks the unvisited web pages with evaluation results, wherein highest ranked unvisited web pages are unvisited web pages most likely to contain content relevant to the search.
