Input: Consider Input: Certainly interesting adventures . This book is definately not as helpful as the first book.  In this book Brian takes the journey and metaphors a bit too far.  He strays a bit too far from the scriptures to make his point.  Keep to the first book definately more helpful

Output: NEG


Input: Consider Input: Excellent introduction to the field for physicists . Perhaps the best feature of this book is that it aims to convey the theory of Lie algebras and Lie groups to physicists. In doing so, the author is careful to give a very simplistic approach so that one not familiar with  the subject can understand it. Not to say that the book is elementary,  since it builds rapidly into the far more interesting aspects of Lie  Groups. A very good read

Output: POS


Input: Consider Input: Delightful . Wintry, restful, appropriate, delightful illustrations accompany one of my favorite Robert Frost poems.  My children will enjoy this poem as much as I do


Output: POS
