Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: This was a gigando rip-off! It does not even contain the "The Owl and the Pussycat," which from the ad I expected to be included. The table of contents is a joke - listing the page numbers of each of the numbered limericks, which could have been written by almost any college freshman after 3 beers at the local bar. There was no attempt at editing, and often a limeick with one line at the bottom of one page would be continued at the top of the next.This is a book which Amazon should be ashamed to list and should be obliged to refund all of the money paid by each person taken in by the listing.
Solution:
Negative
