Example Input: Not it. . I thought I had found the secret to making delicious artisan sourdough bread. I made the starter using grapes but sadly the bread was not up to my expectations. This book turned out to be a waste of money. The secret to the bread I am looking for wasn't in this book. I have tried Ed Wood's book and starters, the special Baparoma steam pan, etc. but am still searching for the perfect bread
Example Output: NEG

Example Input: Not for the solo lawyer; not about marketing, except for the author . I was disappointed by this book.  I am a solo litigation attorney, and I read the book to get ideas on marketing.  It gave me some ideas.  Perhaps the most valuable idea was to focus more on customer service; Dahut has an interesting discussion about exactly what that means and how we can do it better.  By and large, however, this is a book by and for big firm attorneys.  It is about big firm angst and how it can be combated by hiring experts such as Dahut to do extensive consulting work for your firm.  Dahut does not acknowledge, and does not care, that most attorneys are solos or work in small firms, and that we have very different issues than agonizing over whether we have lost our soul by conforming to much to dead firm culture
Example Output: NEG

Example Input: Expensive, complicated, too fancy for me; Too much fish . More fish recipes than your normal cook-in-advance books. I didn't want to buy the book, but my cat spilled iced tea on the borrowed copy (helpful kitty). There were a few interesting recipes, but everything was way too complicated and expensive. I have since given my copy to a thrift store. If you enjoy cooking and eating gourmet recipes, but don't have the time, this might be for you. If you can borrow it at the library (via interlibrary loan if your branch doesn't have it) you can better judge it. I can't recommend it, because I found almost nothing appealing. But tastes are personal, and YMMV.  Just keep the book away from iced tea and cats
Example Output:
NEG
