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: the shipping was fast, as usual by Amazon. The product is terrible, you can barely see the logo, its not a real Colts blue, more of a very dark navy almost purple color. They will be going back. I should have known the price was too good to be true for a product of any real value.
Student:
Negative
