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.

Gripping story . I found this book at my local used book store.  I was a little hesitant to buy it because I was afraid it would your typical teenage agnst story.  But for only four dollars, what was there to lose?  I was in for a surprise and a real treat!  This book not only captures the teenage insecurities that most of us have felt, or are feeling, but it also captures that nervous, excited, almost panicked feeling a lot of us get after graduating high school, and moving on into the &quot;real&quot; world.  The book was unique in many many ways.  The first third of the book was the main character describing a history of her life by describing pictures she had found, and giving a short story for each one.  The second section, told from her point of view, gave the reader insight into her high school life, dealing with peer pressure, school, and dating.  In the third part of the book,  she begins college, and also begins to spiral out of control, and the books tone shows this.  This section is told in third person, as if she is going through so much, that she feels she is watching herself from the outside. I was very impressed with the writing style and the story line.  I would recommend this book to anyone

For designers, directors and academics . This book, one of the few that takes a more academic, rather than practical, view of scenic design, should be required reading for any designer (lights and costumes as well as set) as well as every director. In his designer profiles Aronson shows the reader the different processes that can be utilized to achieve a successful design.  It is also one of the few books that gives the reader an opportunity to get deeper into the history of contemporary American design, as each designer is sure to mention his or her influences and teachers.  Far more useful then the practical books on design in helping a young designer conceptualize, collaborate and create interesting designs.  Unless you want to design in a vacuum, this book is a must rea

Engaging exercises to train your intuition . Famous mathematicians have often emphasized the role of visual intuition;  e.g., Hilbert: &quot;Who does not always use along with the double  inequality a &gt; b &gt; c the picture of three points following one  another on a straight line as the geometrical picture of the idea  &quot;between&quot;? Who does not make use of drawings of segments and  rectangles enclosed in one another, when it is required to prove with  perfect rigor a difficult theorem on the continuity of functions or the  existence of points of condensation?&quot; (from his famous address at the  1900 International Congress). This book is a collection of well over 100  one-page proofs, collected from various sources. The topics range from  number theory to calculus, and most of them require no advanced  mathematics. Typically there is a statement of a result, with a labelled  diagram showing how it is &quot;proved&quot;; in some cases there are a few  auxiliary equations along with the picture. These are not simple, often  requiring quite a bit of thought before the &quot;Aha!&quot; moment.  Working through them is a valuable exercise for the student of  mathematics--having seen, e.g., six different visual proofs of the  Pythagorean theorem, one comes to really *understand* the result, not just  &quot;follow the logic&quot;. I have not encountered any better way than  this book to &quot;see&quot; how mathematical truth is discovered and  proved. It can be valuable as a supplement to courses through precalculus  and elementary calculus. Perhaps one of its best uses is to inspire  teachers to present results in a more lively way then  &quot;definition-theorem-proof&quot; or &quot;just memorize it&quot;
