Example Input: Great book for chefs but it's not a cookbook . This book will tell you what flavors go well with each other, what starch and veggies will match well with a protein, and there are a few recipes.  This book is great for developing your own recipes
Example Output: POS

Example Input: A work for academic readers only . This book reads like a PhD dissertation and focuses on making reference after reference to dozens of other academic articles and books, much like a college research paper. I wonder if these 5 star reviews are from sociology professors because this is very dry reading and I can't imagine a casual reader being interested in reading this book at all
Example Output: NEG

Example Input: Good start to what promises to be a fun series . Wanda Nell Culpepper has got a lot on her hands:  she's a single mom with three kids and one grandkid who she works 2 jobs to support.  Her Mother in Law is a monster--and her ex has just shown up waving around a lot of cash.      When Wanda Nell finds her ex stabbed through the throat with a pink lawn flamingo, her troubles have just begun.  The deputy suspects her, dangerous folks are coming after her looking for something that the ex supposedly left with her.     "Flamingo Fatale" is a good read and an interesting cosy; however, I don't think that Evans hits her stride with her first book.  "Murder Over Easy" is much improved and the third in the series actually promises to be more interesting.
Example Output:
POS
