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: It shocks me that the Scarlet Letter is the most taught book in the nation. It may have much symbolism and so on, but it is a convoluted mess. The author is completely detached from his audience, and for some bizarre reason, he feels he has to explain every little thing that happens in great detail. It is also irrelevant to our modern times. In our days people need to be reading things like Huxley, Orwell, Fitzgerald, Bradbury, Hemmingway, Steinbeck, Salinger, and many other great 20th century writers. This book is only relevant to those interested in the time period which it discusses.
