Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.

Output: Negative


Input: Consider Input: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.

Output: Negative


Input: Consider Input: I am amazed at the high ratings this book received. It was, undoubtedly, the worst book I have ever read. It might have been better with good editing. There were many unimportant characters and many horrible descriptions that could have been omitted. Who really cares about the dogs, many of whom have no relevance to the story. Who really cares about the detailed description of the decor of a room. Yes, I did finish the book that, by the way, had no ending. Toward the middle of the book I actually started editing it. What a mess!


Output: Negative
