| Abstract: | The core algorithm of RoadRunner was analyzed. After analyzing the deficiencies of RoadRunner, a Web information extraction system based on similar pages was designed and implemented. The system architecture was introduced, then the key techniques, such as the method for getting similar Web pages, reliably dealing with Web nosy blocks and automatically deducing rules for extracting data items were presented. |
