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.

Example Input: fantastic reference/crash course . This book is straightforward, breaking down each step of the heroic journey, from the hero's birth to apotheosis, using examples from various mythologies/religions to establish the classical pattern used in literature. If you just want to brush up and increase your ability to identify the pattern in literature/pop culture (ie. Aliens movies, The Matrix, Xena, Buffy, Providence...) this is a handy reference and a quick read
Example Output: POS

Example Input: Great Topic - Terrible Presenation . Well, I just had to try another Dr. Phil book, since it has been a number of years since I read Life Strategies. To be honest, even though he can be a polarizing figure, I have nothing against him. I think his TV is a source of help and inspiration for thousands of people.    This book however, was a real struggle to complete. It was not coherently structured, and the author kept saying things like "This book will show you...." all the way through the book. It felt like I never left the "Introduction" and he was continually trying to convince me (or himself) that this book really would eventually get to the point and that the point would be profound. Instead it really couldn't ever get moving and instead often relied on crass language as a weak attempt to get the reader's attention.    Fret not! There are other books out there that tackle the same general issue, but are far better reads. I recommend:    1. Failing Forward, by John C. Maxwell  2. Today Matters, by John C. Maxwell    Again, I have no issue with the author, and applaud his efforts. However, in writing a review to my fellow Amazon customers, I must strongly recommend that you spend your time on more impactful literature within this genre. Best of success to you in reaching your goals
Example Output: NEG

Example Input: Review of &quot;Ten Days that Shook the World.&quot; . Although this book may be so brilliantly written by John Reed, I found it to be too laden with historical details, and even somewhat confusing for someone who is using this book to merely familiarize her (him)self with the makings of the Russian Revolution for the first time.  The book provides with a glossary of Russian terms, events and political parties necessary to understand it but even so I found myself hopelessly stumbling through the chapters trying to pick up information here and there.  However, due to my lack of knowledge of Russian history I was unable to piece together any of the information.  So, in frustration I gave up and relinquished the book to somebody who knows somebody who is a &quot;history buff&quot;.  From this experience I learned that if you want to familiarize yourself with a historical event about which you know truly nothing, it is always better to read a book which describes that event perhaps in a very broad outline form on the first page of the book.  The rest of the book should be written according to that outline. A glossary of main events would also be helpful.  On the other hand I do realize that most historical events are way too complicated to be approached in this manner.  Anyway, if you would like to expand your knowledge about the Russian Revolution, I highly recommend this book.  However, if like me you are looking to merely acquire a basic knowledge about this historical event you will get lost in its too many facts
Example Output:
NEG
