Ex Input:
Barrio Boy . I found "Barrio Boy" to be very boring, as a matter of fact I didn't even try to finish the book. So save your money and buy something better

Ex Output:
NEG

Ex Input:
REMEMBER, IT'S A DIARY!!!! . Some of the reviews listed criticize this book for it's "opinions," "harsh jugdements," etc. This was written as a private journal, and not to betaken as an indepth, researched, polished project. Just let him speak!

Ex Output:
POS

Ex Input:
The Missing Element . An excellent and important story that needs to be told over and over again. But for those of us who use non-fiction books such as this for research as well, this book lacks a crucial element--an index. I could not recommend this book to someone researching information on the Holocaust because there is no way for someone to retrieve important information without laboriously searching page by page through the book. When will publishers learn what researchers and librarians know, a non-fiction book without an index is not complete

Ex Output:
NEG
