Example Input: This Book is a Hit! . I am returning to the market after several years in the motion picture industry and was looking for a refresher on the business end of photography.    Vik Orenstein has provided a wonderful primer for both beginner and professional alike, and I unreservedly recommend this book to anyone who is serious about pursuing a career in photography.    She thoroughly covers necesary subjects such as choosing CPAs and lawyers, networking, and the various photographic markets available for pursuit. She does all of this in a winsome way, relating both her successes and failures as she developed and grew her own studios.    If you are considering entering the field of photography as a professional, seriously consider purchasing this book. You will be making a very wise investment
Example Output: POS

Example Input: Novel goes nowhere, can't believe this won something . Talk about a waste of time!  I was wondering if it was just me so I asked several friends who dutifully read this prize winner and they said they could barely get through it.  It is boring, tells you instead of shows you, hyperactively jumps around the timeline like a flea and provides no payoff at all.  I also found the protrayal of the grandmother's flirtation with Islam to be shallow, un-informed, unbelievable and ultimately dismissive. Don't waste your time on this or your money. Luckily I had picked it up at a book sale for $0.25, about what it was worth
Example Output: NEG

Example Input: Rush and Me . I used to be a good friend to Rush. I listened to his program all the time. When I first saw this book, I ignored it. Finally, after it had been in the window of our bookstore for several months, I picked it up and looked inside.    I was amazed!     However, I had to put it down because I thought it was too negative. It called Rush names. I did not need to have that. Finally, I tried getting it at the library, but they said they did not have a copy, because they said it was "too controversial."    So when the price came down, I bought a used copy for a couple of bucks, and read the whole thing.    I was amazed some more!    Rush used to have 20 million listeners to his talk show. He was a legendary, rich talk show host. This book tells you exactly how Rush became a rich, popular talk show host. And he is thinner now that he has recovered from his unfortunate drug problem. And you know, that sort of thing could happen to anybody.    But I had trusted Rush, and his VALUES, and I kind of felt he let me down. So for me, the title is not appropriate. Rush Limbaugh is a Big, Rich Talk Show Host who Cuts Corners on His Values would be a better title. Rush is no idiot, either.    Now, by some "coincidence" Al Franken is a talk show host too. And, I bet he learned how by studying how Rush did it!    If Franken can do it, YOU can do it!    Don't miss out on this GREAT opportunity!    Get a copy. Look how cheap it is now. Tell your friends
