Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: If you REALLY want to write correct, you won't write "correctly." Yes, it's in common use but it is, by the rules of grammar, incorrect. It's an overcorrection, an unnecessary addition. Here's a simple rule of thumb: Substitute the word "fast" where you're thinking of adding an -ly. Would you say "How to Speak and Write Fastly?" No. Same part of speech, but it somehow escaped that stupid -ly trap.
Solution:
Negative
