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 price is too high for a VHS tape. Also, the title is misleadig, as Latin dancing has nothing in common with Argentine Tango. If you are NOT interested in authentic Tango Argentino, and don't mind paying the high price for ballroom instruction on tape, then this video is for you.
