Example Input: So far I'm very happy with my boots.They fit well and seem very well constructed.Time wiill tell how they perform but so far so good.
Example Output: Positive

Example Input: I think AFX's take on "Run the Place Red" is incredibly fun -- it makes me want to jump and shimmy each time I hear it. Now, I'm not a huge fan of ragga, but ragga-jungle-drill 'n' bass? I think it's a genius combination, one that only the demented mind of Mr. James could discover. You can barely understand the vocals beneath the percussion -- they're more flavor than anything else. As for the two noise tracks, they're rather interesting the first time around (not to mention intense on the squeals), but I don't think they stand up to repeated listens. Mostly because I don't want to go deaf.
Example Output: Positive

Example Input: As somebody else wrote earlier, it is so much great music out there that these I.Com tracks sound awfully poor and dry to me; maybe if that album would have appeared in the 90s it'd have sounded slightly more surprising, but just a few weeks before Bjork releases Medulla, and definitely late after the Chicks on Speed albums (and without even 10% of their musical imagination) Miss Kittin with her new release is making electronic music sound like a joke, and conceived for people who never heard about Warp, Rephlex and the intelligent vast worlds of true electronica. To avoid.
Example Output:
Negative
