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]: A review on the author . Although the book is great, it speaks for itself and I'm not here to review it.  I emailed the author, or someone who works with her, at the email address I got from Jan's website.  First of all, a little background.  I have a two-year-old border collie/lab who I've had since he was seven weeks.  I adore him.  I have been working from home with the occasional temp job up until two months ago.  I now work 5 days a week outside the house.  I wrote to this person asking advice on certain things relating to walking the dog, and mentioned the hours my dog is being left alone while I'm at work.  My response was that I am &quot;selfish&quot; and unfit to have a dog.  This coming from someone who was once so clueless about raising dogs that she put one of her own to sleep.  I have been looking into getting a dogwalker for my pooch, which as a person concerned for dogs, she could have suggested.    But her only suggestion was my poor dog, I shouldn't have him.  Whereas the book is a good read with good methods, I would suggest a second thought before asking her or her staff any questions personally.  She, or whoever that was, is rather selective in the dogs she'll help according to what she thinks of their owners.  It was a negative experience trying to get any kind of advice from them.  Rather than pointing out something wrong and offering suggestions to rectify it to someone who is obviously open to change, she chose instead to say, Sorry!  Not interested!  Not at all what I had in mind for someone in her position and with her passion

[EX Q]: Great Book For Interested Physics Students . When reading books about Chemistry or Physics, the level of depth is usually to the electron, proton, neutron, and there is usually some mention of quarks and antimatter and dark matter, but with no explanation of where these ideas are coming from. This book gives a good, nonmathematical description of the Standard Theory (Model) of particle physics, which gives a good account of what particles are known, how forces are treated using particles called Bosons. The books will answer any questions about what is known, but without proofs. I plan to study physics as an undergrad, and probably grad too, and have always been attracted to learning about the fundamental particles. This book was very satisfying for me, and will be for other interested students. Kane provides information about not only the standard theory, but also the facilities where research is done, where the field is going, and what a future student can expect. A quick read and definitely worth the time
[EX A]: POS

[EX Q]: good basic book, but lots of errors and typos . It's a good basic overview, but the errors in the code snips are just too frustrating. I bought it because it was recently published (2006). But trying to get PEAR to work (DB.php has been superseded by MDB2.php) and even the simple form were exercises in futility.      If you do use it get an AMP package (google: Uniform Server) and skip the install section. You'd think O'Reilly could include and AMP stack on a CD in the book and use that 20 pages for another exercis
