Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: Ok...ditto to all the other comments. I have searched all over for days for a blue jewelry earring / ring box for my 87 yr. old mom for Christmas. I am set to order it, then see you can't choose a color. What a big waste of my time and effort. This was just what I was looking for and no color choice. How dumb is that!
A:
Negative
