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: Product is as shown but they didnt have it in stock and it took them almost a month to ship. And then instead of sending next day to compensate they sent it regular mail so it took another week to receive. Not too happy with their customer service.
Student:
Negative
