TASK DEFINITION: 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.
PROBLEM: Preposterous! . This book begins with the absurd claim that 'the natural numbers -1, 2,3, 4 etc- appear to have been present at the birth of the universe; part and parcel of the original material from which was knit the ever-expanding continuum of space-time.' The author does not explain in whose mind these numbers are supposed to have appeared or how a concept can be present without a mind to concieve it. Like many mathematicians he seems unable to grasp that mathematics is a language. Thus it's not uncommon to hear ridiculous statements like 'the universe is governed by mathematics' As if numbers exert forces. But this is the first time I've encountered the claim that numbers existed prior to life!

SOLUTION: NEG

PROBLEM: lack of examples and horrible explanations make a ghastly diffE text . Because the guy who initiated the project of writing the book is here at Rice, the rest of us are unlucky enough to have to use this book. If your class uses this book, prepare to go to class. All the time. That's because if you fall behind, the book does not do a good job of explaining things to you. Examples are generally vague and only apply to a few types of problems provided at the back of each section. A lot of the time, I'd find myself stumped on a problem, looking back, and realizing there was no example problem for me to get ideas from.    Yes there are lots of problems and that's good, in a way. But what's the point of having all those problems if the book never teaches you how to do them?    Furthermore, it is a poorly written book. Generally, reading through the book is like searching for a needle in a haystack. Literally speaking. You spend all that time figuring out what the authors talk about and once you figure it out, it was not even worth all that time.    So go to class. All the time. If the prof isnt that great, get yourself another workbook. I havent seen Schaum's but I'm pretty sure they'll do a better job on covering the topics than this text does

SOLUTION: NEG

PROBLEM: Horrible! . Elaine Feinstein obviously didn't have access to many sources for this VERY poor biography.  Sylvia Plath certainly cast a huge shadow over Hughes' life, but we get very little insight into the Hughes-Plath marriage from Hughes' perspective.  Feinstein doesn't know how to write biography--a difficult art form for anyone who isn't willing to hurt feelings or take criticism.  Feinstein didn't want to annoy ANYONE with her lame book.  Dates are given incorrectly and names are misspelled to the point at which I wonder exactly how much attention the author was giving to her sloppy manuscript, and how quickly she felt she needed to get it published before somebody else decided to cover the subject of Hughes in a thorough, responsible fashion.  Don't waste your money on this book.  Check it out of the library if you must, but don't buy it

SOLUTION:
NEG
