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: Once again, Sandra Lee is out to poison America with her high-sodium, preservative-laden recipes. This book is a joke. Under no circumstances should anyone who prefers not to die before the age of 45 should buy this. Heart attack city! Oh, and crappy food. Did I mention how bad her recipes are? Terrible. The scourge must be stopped! Whoot!
