document: GoGetIt ! : a tool for generating structure-driven web crawlers We present GoGetIt ! , a tool for generating structure-driven crawlers that requires a minimum effort from the users . The tool takes as input a sample page and an entry point to a Web site and generates a structure-driven crawler based on navigation patterns , sequences of patterns for the links a crawler has to follow to reach the pages structurally similar to the sample page . In the experiments we have performed , structure-driven crawlers generated by GoGetIt ! were able to collect all pages that match the samples given , including those pages added after their generation .
