Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: Thank you, Erika Vause, for your positive review! I absolutely love this book! I had heard of this novel, but never considered reading it because the plot simply did not interest me. Then we read it in our academic English class (10th graders) and I was absolutely astonished!! Not only by the magnificence of the book--its themes of guilt and redemption are powerful and heart wrenching--but by the ignorance of some of my peers. It was obvious that their dislike sprung from the fact that they did not understand it! Please, please--read this book! You will not be sorry! I promise.
