Example Input: vampire Christopher . Christopher Byron's sensibility indicates that he is a small-minded, pathologically envious little weasle of a man, who tries to puff up his empty meaningless life by attempting to denigrate a great woman who has brought great beauty and grace to our culture. Unless you're one of those nasty-spirited people who find glee in joining the pack of hyenas who hate powerful, brilliant, talented women because the light from great women's souls is too bright and reveals too vividly your pathetic life, avoid this book. Byron is simply a mean little vampire, trying to suck money and notoriety from the life blood of Martha. Shame on John Wiley & Sons for publishing this book
Example Output: NEG

Example Input: A Great book for the Early Childhood Classroom . This book helps you look at the big picture from beginning to end. Nature should exist in the classroom all year around. I love the open ended growing activities and setting up a growing center. I'm in the process of doing this in my classroom and the children love it. Check out their other books on structures and water too!
Example Output: POS

Example Input: Excellent short review that is true to its title . This is an excellent short review of European quest for a language to unite its disparate nations with each other and the rest of the world. I thought that the book did an excellent job of staying on the subject and illustrating the progression of thought in this area. It does confine itself to Europe and time period as defined in the beginning of the book. That is excellent, there is simply no other way to cover as much ground as the book attempts to do, and I feel that it does suceed admirably. As usual, Eco's erudition and research are amazing. This book is published in the context of a European series of books about Europe and I wish there was a similar book series that would cover this ground for Far East and India as well. I am sure people there worked on the same kind of problems. Some of the problems with languages and methods described seem so obvious that one has to wonder what the authors themselves thought about them. Of course, this is a whole other book series. I wish there was a 4 1/2 rating as I do not think this is truly a masterpiece, but certainly a very very good book from a very very good author of fiction and non-fiction. A bonus for fans of Focault's Pendulum -- a lot of data in that fiction book refers to work discussed in this non-fiction work. Great fun
