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 junk really stinks (literally, it smells horrible)!! I've used better products and those other attractants did trigger responses in females. I've been INSULTED by the females at my job after using alter ego and been told things like "what in the world is that new cologne you're wearing, it doesn't smell good". I told my wife I was wearing a new type of "after shave" and she hates it so much I had to promise NOT to wear it to bed. Don't believe the hype of Alter Ego, there are far far far better Pheromones. It's apparent they tried to give it a MASCULINE tone, but they went too far.
