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.

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

This book was terrific . I loved it and look forward to more of her books.    The lead character was very likable and it was fun watching her journey through the break-up and divorce and how she was able to cope.  It is a book of hope for anyone who has had marital problems or just pure fantasy and fun for those who have not

Don't leave home without it . Recently, my wife and I went on holiday to the Bordeaux region to tour the vineyards. This book was extremely helpful in planning and executing the trip. As geography and 'terroir' are key to understanding wine, I know of no other book that gives a better overview of this mysterious and elegant beverage. It's a must buy for wine lovers
