20080235163 | SYSTEM AND METHOD FOR ONLINE DUPLICATE DETECTION AND ELIMINATION IN A WEB CRAWLER - As part of the normal crawling process, a crawler parses a page and computes a de-tagged hash, called a fingerprint, of the page content. A lookup structure consisting of the host hash (hash of the host portion of the URL) and the fingerprint of the page is maintained. Before the crawler writes a page to a store, this lookup structure is consulted. If the lookup structure already contains the tuple (i.e., host hash and fingerprint), then the page is not written to the store. Thus, a lot of duplicates are eliminated at the crawler itself, saving CPU and disk cycles which would otherwise be needed during current duplicate elimination processes. | 09-25-2008 |
