Plagiarism check

[xapss]

Hi,

 

I was wondering, if it's possible (actually i know it is ) to analyze my string.

 

I want to compare my string with fields in mysql, and give it a certain plagiarize check.

For instance, I have $var1, which is about 200 words (about 10 sentences). I'll search for a few of those 200 words, and the script finds about 170 words in the a sort of the same phrase, but in another field. It will then give a score of 170/200 = 85% plagiarism.

 

This doesn't seem too hard to do, right? If something's not clear, please tell me.. However, is this possible? I couldn't find any clear examples on the web..

 

Thanks in advance,

 

Maurice

nothing ever seems hard to do, until you get to do it..

Yes, thanks for the replies. However, I checked hip2b2 before, and I couldn't really find what i was looking for. Perhaps I haven't been specific enough.

 

What I want is the following: I've got var1, then, I want to check for much it overlaps with an entry/record out of the database. It will eventually pop up a percentage. So I do not need google (hip2b2 only shows the results, does not analyze them), I just pick them from my own database. Any help?

 

Thanks in advance,
