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: Succeeds as a book, Fails as a social stimulator . One only need read the reviews of this book from both professional and amateur critics to see that, if Gross's purpose is to aid the reconciliation between Jews and Poles, he has utterly failed. Unlike books dealing with heroes who surmounted prejudice to create miracles, this book stirs an old cauldron of hatred, freshening the pot. Readers without a more complete history of both the Jews and the Poles are especially at risk. Jan Karski's "Story of a Secret State" which was actually written DURING World War 2 and deals with the situation in a balanced and informed manner would be a good companion book to this. Additional reading should include a comprehensive review of Polish-Jewish relations, beginning with the Charters of Sanctity responsible for so many Jews living in Poland in the first place. When Jews were being blamed for the plague and slaughtered throughout Europe, the Poles opened their doors and gave them a homeland, where they thrived for many centuries. The Lutheran armies of the Swedish invasions brought anti-Semitism. Later, Poland was divided by Germany, Russia (with a German Queen), and Austria, an occupation which lasted for more than a century. These countries waged a cultural war on the occupied Poles, determined to convert them to their own. The Poland of WW2 had only been liberated for a few decades. The equivalent of Ronald Reagan's era to today. Many of the citizens were of German descent and actually aided the Nazis in their fight against other Poles, not only Jews. And although the sickening atrocities recounted in this book are inexcusable, one must keep in mind that they were committed by people driven to collective madness by decades of oppression, poverty and terror. We've seen similar episodes in recent years in the Balkans and Africa and elsewhere. Even the Israeli human rights organization B'Tselem maintains a website decrying violations by hate-infected Israelis today. Poland has only regained her true national and cultural identity in the last two decades, after two hundred years of occupation. Pope John Paul 2 was emblematic of that spirit, and Poland's support for Israel and attempts to honor her Jewish heritage, embraced by her youth of today, are evidence that she has turned a corner and is nurturing the great ideals of her past. The Poland that was once a mighty power, yet never imperialistic. The Poland that was the Promised Land for Jews in the Middle Ages
Example Output: POS

Example Input: your head will split open and ooze goop after reading this . All I can say is pass me some aspirin. This is a dozy of a bad novel. As it says on the dust jacket, a Supreme Court law clerk grabs a petition and ends up becoming deceased. Its up to the brother to uncover the truth by finding the real killer who had let a poor black man rot away for a crime he did not commit. At the same time the brother contends with mysterious bad guys out to get him and stop the unearthing of the evidence. Not only does he deal with his family, but his brothers friend, a sexy young law clerk herself and the duplicity on the bench she works for. And that's only the start of the plot. Its really pretty bad, it descends into mired pretensions and goofy resolutions. The characters are so shallow that you are left with little notion of who they are except for a faint nasty after taste over their conceded ways. Baldacci is along with James Patterson and Dean Koontz one of America's worst authors. If you want an author who writes on a similar vein to this, try one of Harlan Coben's last four or so stand alone thrillers with out the character Myron Bolitar in it. Or for a more sophisticated read, look for Denis Lehane, he wrote the amazing Mystic River, but his PI series located in Boston is pretty good as well.
Example Output: NEG

Example Input: Post-modern science fiction . Maybe I'm just not the right demographic for this novel, but I hated the beginning, tolerated the middle and put it down permanently near the end. The model is the Canterbury Tales of Chaucer, but I don't think it works. I just never got interested in the characters enough to care what happened to them and for me, the story--stories, really--never came into focus. I guess the New York Times Book Review should have tipped me off because they compare it to Frank Herbert's Dune and the Foundation series of Asimov, both of which, in my opinion have aged really badly. I never realized how bad Dune was until I saw the awful movie of it. The fundamental metaphors operating in Hyperion seem to be backwards living. Well, ok, but I just don't see what it is a metaphor for. Nor, by page 473 where I finally gave up, did I care
Example Output:
NEG
