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 book doesn't even come close to the quality I have come to expect from Maeve Binchy. The story lines never come together. Basically, the entire book is a set of character sketches. Yes, it kept my attention and I did finish the book, but by the time I was finished, I regretted spending the time on it and fussed at my mother who told me in advance that this was not one of her favorites. (She should have been a bit more forthcoming!) I would not recommend this book; on the contrary, I would discourage someone from investing any time on this book. There are many, many better books out there, including all others by still-a-favorite Maeve Binchy.
