User:CorenSearchBot

Function
This bot patrols newly created pages in the main space, and matches the contents against a web search. Pages found to contain a significant portion of text taken from another web page are tagged (and categorized) for human attention according to some guidelines:


 * Pages including little or no contents beyond that of the external page get a slightly more stern tag.
 * If the page is a copy of another Wikipedia page, then the page is also tagged (but with a Wikipedia-specific tag).
 * Web sites can be whitelisted as having a permissive license.
 * If one of the accepted (configurable) attribution or permission tags is present on the page, then it is ignored.

If the 'bot modifies the newly created page in any way, then it will also leave a message on the creator's talk page, and on suspected copyright violations to bring attention to the apparent problem.

Additionally, the 'bot watches and/or updates a number of subpages under its user page for runtime configuration, directives and status information.

Operation
The CorenSearchBot is meant to function continuously, without direct human supervision.

Program
CorenSearchBot is written in Perl and takes advantage of the new Mediawiki API for everything except page modifications.

The source will be made available once the author is reasonably convinced it works well enough to break neither Wikipedia nor Google Yahoo (for now).
