This sounds like the kind of problem a plagiarism detector is designed for.

If, in fact, that is what the OP is after, s/he may benefit from looking at the nodes mentioned here: Re: Finding plagarized content.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
