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: This is the only magazine I read regularly in college (25 years ago) that I still read now. Great articles on all kinds of issues and they do try to cater to black women from ages 20 to 55 or so which is not easy. Lately, it's been a little flat -- both in terms of magazine size and in the depth of the articles. I'm renewing it one more year and hope it improves during that time
