cwcatd — Clear Web automatic categorization daemon
cwcatd [-hv] [-d ] dbglev-f cfgfile
The cwcatd daemon handles automatic categorization of WWW servers. If categories for a requested URL are not found in the Clear Web database, the http-proxy(8) or the icap-server(8) can optionally request automatic categorization of the URL. These requests are appended to a queue that is processed by daemon cwcatd.
The daemon reads uncategorized URLs from the queue. For each URL, it tries to download the referenced web page. The downloaded page is passed to an automatic categorizer, which tries to assign categories according to a heuristic applied to the page content. If it succeeds, the result is stored in a local database.
Future requests to a locally categorized server will get categories assigned according to the local database. If categories of the server appear in the downloaded Clear Web database in its periodic update, the result of the automatic local categorization will not be used any more.
