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: Concise and Precise . Peter Drucker is a subject in and of itself.  His insights into the movement of people and their actions are legendary within the business world.  This book provides a clear, essential summary of his life work.  If  you are in business (which is most of us), if you are looking for ideas, or  just plain interested in who thought up some of the &quot;common&quot;  business maps of the day, chances are you can read this book and find out  that they are all linked to Mr. Drucker.  This is not your normal  biography- there is real substance here
Example Output: POS

Example Input: Another fine book by the master . Poirot is given a case by his old pal Spence which takes him to a small village, where the fussy detective must unravel clues behind a crime in which the main  suspect has already been arrested and sentenced... Hercule's indignities at the run down boarding house he's staying at make up the bulk of the story's humor, but the mystery is great fun, too and I doubt anyone can guess the killer, unless you're paying amazingly close attention. The characters here are some of Agatha's most entertaining, and Mrs Oliver, with her uncanny intuition,  always makes a nice flighty side kick..
Example Output: POS

Example Input: Only for suckers . Who would read all these reviews, and then actually buy this book? This book is an unfair attempt at pandering to the doddling whims of a major portion of our population...the suckers...of which I am obviously one, because I did read the stupid book! It took me almost a year to get through it - one half paragraph at a time before I would fall asleep each night. If it wasn't for Jordan, I'd have a hard time going to sleep at all. It doesn't even deserve 1 star
Example Output:
NEG
