[Wikimedia-l] Copy and paste

[Federico Leva (Nemo)]

How hard would it be to set up a tool like the software that as far as I 
know the MIT uses to automatically check plagiarism among thesis etc. 
submitted to their digital library, checking the text of all Wikimedia 
projects against e.g. newspaper websites and Google Books, and then 
publishing the results in some visually appealing way to show how much 
newspapers copy from Wikipedia and each other?
On it.wiki we regularly see complaints and unhappy discussions about 
newspaper articles which are just a copy and paste from Wikipedia and 
still feature a "COPY RESERVED" warning without citing any source... 
newspapers are by definition arrogant, so nothing can be done to stop 
them, but an informative tool would be useful and might be as effective 
as wikiscanner was with regard to IP editing from organizations.
