In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
One example is below.
Q: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for  our earth will find this hopeful
A: POS
Rationale: The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.
Q: Thin characterization . I agree with one the comments posted below. The main problem with this book is Mitch is a totally one-dimensional character and it's impossible to find any depth in him. Over the course of the book he doesn't change, he's unsympathetic, and by the time we've reached page 500, we don't know anything more about him than we did on page 10. I found myself dying to get to the end of this book, just so I could start another book with some substance and some well-drawn characters.    Another major problem is that most of the characters in this book use the same wise-cracking speaking style so there is no sense of the characters being different from each other in any way.    Overall, I thought this was mediocre and a bit of a waste of time
A:
NEG
