be new and are easily identified through comparison with
the list of previously accessed URLs. The second problem
is solved by URLChecker which automatically classifies URLs
as being pornographic or not. URLChecker improves productivity

associated with the URL is pornographic or not. Most conventional
systems use only text processing and rating systems.
