Crawler (1B) them executes its crawling assignment by filtering the encountered content and extracting only that which is new or changed (4). Crawler (1B) then returns this content (4) to at least one data center and any interested web mining application (5). By using the crawlers (1A-E) to filter the data and only return or notify regarding, the fresh content, less bandwidth is needed to get the information to the web mining application (5).
