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: Waste of money . 98% of this thin book is about how many buttons a certain uniform had on it and what type of boots a certain unit wore.  Almost nothing about the Italian Army of WWII was in it.  A more appropriate title would have been "The Uniforms of the Italian Army 1940-45: Africa"
Example Output: NEG

Example Input: A must-read. Period. . I recently read Berlinski's book as well as Bawer's "While Europe Slept"  and "Anti-Americanism" by Jean Francois Revel. These are very important books in that they shed light on the mythology of the American Left, according to which Europe (Western Europe, that is) is the Promised Land. Since they detest America, they need to find some model to emulate. Well, on closer inspection Europe is not it. Today's Europe had been left hopelessly behind. It lives off the corpses of the past, and having been given a sense of security (by the American foreign policy and its military might) and illusion of prosperity (originally spawned by US economic aid and today dependent on US spending power!), they feel superior to the US. Anyone who ever debated angry Europeans will quickly discover that the superiority is really a reaction to their profound inferiority complexes.    Disregard the one-star reviews. An M. McDonald below claims that the book is "short on facts"... This from a guy who claims that Germany is the world's largest exporter... Forgot to mention though that it's the larger exporter of MERCHANDISE. If you add services, the US exports are at $1.15 trillion vs. Germany's $893B. And, thanks to diversification, the US is less vulnerable to global economic slowdowns. McDonald's is wrong. He's wrong about public education too: Europe's schools are "vastly superior"?...Does he have any idea what goes on in the schools of Paris, London and Rome?? he says China not seen as a threat to EU? Anyone who's been to Italy recently, with interests going deeper than gelato, surely must have seen numerous campaigns against Chinese textile imports. My bet? In 5-6 yrs we will be buying superior quality suits made in China for $500 vs. Zegna's $1800 outfits. Indeed, nothing to worry about. Etecetera, etcetera.    Read this and the other books I mentioned so you can be immune to and be able to eloquently respond to this type of leftist pap
Example Output: POS

Example Input: Overkill, Indeed . I completely agree with the reviewer who deemed this novel "overkill" with regards to the puppy mill preaching.  Those of us interested enough in dogs to pick up this book and read it are already well aware of the puppy mill industry.  This choir member did not appreciate being preached at for 45 pages of a novel that would have been better spent with more plot development.  Also, I got a little weary of all the explanations of dog training and AKC show terms and slang.  Again, those of us interested enough in dogs to pick up this novel already know what UDX, CDX and OFA stand for.  Readers interested enough in dogs to pick up this book but do not know what BOB stands for, what "finishing" a dog means, or what an Open class is would probably take the time to find out.  I would have preferred a Patrick O'Brian appraoch in regards to the terms and slang.  Just throw 'em out there for those of us who know, and pique the interest of those that don't.  The way it turned out, however, is that one hundred and fifty pages of a 256 page novel were all either dog show terms explained, or extolling the evils of the puppy mill industry.  I am a bit amazed that Ms. Conant does not say anything at all about the average "backyard breeder" who knows nothing of breeding dogs and wants to do it simply because his dog has papers, who do just as much damage to a breed as puppy mills, if not more.  Go figure.  I have two other Susan Conant Dog Lover's Mysteries to read, and after this first, I am a little leery of even opening the covers
