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.

[EX Q]: Only for first year, if u are doing indepth o-chem then this isnt it . Mcmurry is a colourful and over-generalized textbook that presents the most fundamental concepts of organic chemistry without fully elucidating on their logic. Mcmurry's style is to induce learning of 0-chem via memorizing of reaction mechanisms, and other trivial components.    The only reason you should buy this book (same reason I did) is if your o-chem course is based on this; that being, this is your prescribed text. It is far too difficult to study organic chemistry with another textbook. However this may not be the case for this edition of Mcmurry. Organic Chemistry by Wade has the same chapter format, covers essentially the same thing but treats  the fundamental principles with more depth; allowing the reader to appreciate the finer points of organic chemistry.    One thing that irritated me the most about this book was that there is no appendix for IR frequencies of major functional groups, and mass spectra is barely covered. It is at best just mentioned...nothing more. Wade treats the interpretation of spectral data with more clarity and depth...something which is essential in second year chemistry.    All in all this book doesnt even provide a good grounding in the basics. When it discuses KMnO4 oxidatation, that at least should be a review of redox.     The chapters on Substitution and elimination reactions as well as further chapters in aromatic chemistry are satisfactory, but it is the basics that are lacking. I would suggest for first time o-chem students to consult Wade and compare it to the writing style of Mcmurry. Albeit Mcmurry is very nice and colourful, you will regret its lack of depth and its over simplification of organic chemistry.    The book itself is supplemented with another spectroscopy book here in Australia, which suggests the severe lackings of this book. This has been inherent in it for the last three editions...Not too happy with it
[EX A]: NEG

[EX Q]: totally suprising (in a good way) . this book was totally awesome! i mean people think that a sequel would just completly suck but no! it was great. i was very suprised how the author pulled me in with all the quirky romance, AGAIN! i can not express how great this book is. BUY IT! READ IT! anybody who loved the first one will abosolutly without a doubt love the second one
[EX A]: POS

[EX Q]: Disappointing . The book starts on the premise that competitive strategy is a complex subject and that Michael porter did give us a good structure/framework to analyze this phenomenon to succeed in the market place. Then the author is quick to add that among all forces analyzed by porter, "barriers to entry" is the most significant factor that affects competitive strategy. This is how the author sets the stage to explain "Competition Demystified"    With this quick and firm conclusion on the most significant factor affecting competitive strategy, the book starts off with case after case to justify this hypothesis. To simplify things, it looks at sustained profit margins and continuity of the key players in the given space as a proof for entry barriers. This approach is perhaps to support the second part of the title of the book "A Radically Simplified Approach to Business Strategy ". Granted that the cases discussed do justify the assumptions and are supported by hard facts or published numbers. But if competition lends itself to just a couple of variables, then every company can follow the strategy and hence no competition at all!. In fact one can say "The end of competition". Kindly recall "The end of history..."    The book however deserves praise for use of  Game Theory in a simple non mathematical approach to analyze competitive situations and the behavior of the players. But again, this approach is just a part of the problem and not a full explanation of competitive strategy.     Given the speed of globalization and technological changes especially the internet in the last decade, the book fails to incorporate such forces that significantly affect the success of global firms.    Too voluminous, and fails to impress on what it sets out to accomplish.
