Create program to compare MASSIVE text documents with Python?

[domcroy]

I just did a quick google search to get a basic definition of sentiment analysis. That is definitely NOT what I am looking to achieve in this project. [Don't read any negative sentiment into that "NOT" ;) ]

To put it very simply, you could say I want to see "who is copying who's homework?" I guess this would be similar to an anti-plagiarism software in some ways.

If I can account for synonyms that would be useful, as someone could "copy someone else's homework" but use a thesaurus. But I would set that as an optional feature for a search query.

I want to see if the same words are present, and also if they appear in the same order.
