Example Input: A beautiful book . This set of articles, originally written for magazines and catlalogues, is one of the most eloquent collections of mountain writing I've yet come upon. The book is divided up into chapters such as 'Climbing with Style', which features articles about "the whole art of natural protection" written at the the start of the clean climbing revolution, and 'Further Aborad' which includes the authors account of a climb on Ama Dablam.    One of the features I most enoyed about the book was the introductions to various historical figures such as Smoke Blanchard and Royal Robbins. And the memoir style accounts of what it was like for a small band of climbers to live in the mountains away from civilization getting their kicks out of the "simple joys" and living in bare subsistence, long before climbing turned into the popular sport which it might be called today.    Doug Robinson is well qualified to write what he does, and his style is nice and clear without being base. Most of it is written in an autobiographical style, dealing with developments on the climbing and skiing scene for wenty odd years. If you are partial to a bit of Dharma Bums then get this book. Also anyone interested in the history of the Sierra Nevada
Example Output: POS

Example Input: Not one of her better ones... . I've been a fan of this series for years, but this one was really disappointing. One almost gets the impression that Braun herself has lost interest in the series...(IF she even writes the books anymore!?) Of course, the books have always been slow, but they did have a certain charm to them, making them the perfect bedtime material...but, boy, did I sleep well,when I was reading THIS one..
Example Output: NEG

Example Input: Misleading . I have been a huge fan of Michael Crichton for about 25 years.  However, this book is misleading and dangerous.  Almost every respectable scientist in the world now agrees that global warming is real and that we are greatly accelerating this problem (except some scientists affiliated with the petroleum and automobile industries).      Writing a book that disputes global warming would be like writing a book that disputes the holocaust - Mr. Crichton could just as easily have written a book about how the holocaust did not really happen, and provide plenty of "references" to support this premise.  Tragically, in the long term, global warming could be far more destructive than even the holocaust.      I hope that someday Mr. Crichton recognizes that, in addition to his enormous talent for entertaining, he has enormous influence on people's thoughts and actions through his books.  There is a quote: "With great power comes great responsibility."  But in this case it would seem: "With great power comes great profit at the expense of the planet.
