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: I'm a fan of classics, but I could not force myself to struggle through this book. I could neither identify with the characters (Tess especially seemed extraordinarily weak-willed and passive) nor follow through the endless description of the novel. Iw ould suggest a different book
Student:
Negative
