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: Bought this to add to my "British Rail Journeys" collection only to find that it is the same program that was included in British Rail Journeys: Vol, 1. from another distributor which is cheaper and contains two programs.(See my review.) No reason not to buy this but be advised that it is something you may already have.
Student:
Positive
