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: I was hoping to have a condensed, to-the-point, informative guide on giving birth. I had missed my window of opportunity to be in a class and decided I preferred to be able to watch a video from home anyway. I feel that a lot of time is wasted in this video with theatrics and cheesy humor. I ended up fast forwarding through a lot of it only to realize she was still desperately trying for laughs 5 minutes in to one point.I am probably going to purchase another video simply for the fact that her style irks me!
