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.

Example Input: save your money: poor translations/newsprint-like book . You don't need to trust me--you can look inside the book and get a load of the first translation of the "Frog King" which is unreadable.  Someone just took an old translation and reprinted it on poor quality paper.  This does not do justice to the tales
Example Output: NEG

Example Input: Not flash cards . The content is good, but these aren't actually flash cards. It's a bound book with very thin pages and two words to each page. Studying with flashcards is best done by testing one's self with cards, slipping failures back into the deck for near-term review, and setting repeated successes aside. This isn't possible with a book.
Example Output: NEG

Example Input: modern, yes; but very few homes available as prefabs . I was disappointed with this book.  It includes profiles of 15 architectural firms.  Seven of those profiles were of firms that have done one-off architect-designed homes made largely of pre-existing materials (usually shipping containers).  That is not my definition of a prefab house.  To me, a prefab house is one that I can order to be built on my lot.  Of the eight firms that offer prefab houses, for three of them only computer-generated images were presented (not photos of real houses).  That leaves only five firms offering prefab houses ready for market.  Of those, one builds 10 houses per year in Finland.  Another is in Australia.  Two offer only really small homes (generally intended as second homes).    The book does include (small) design plans and many photos for most of the houses.  However, the fact that very few of those homes are available for me to purchase makes the book almost useless.  [...
