Ex Input:
Possibly the worst book I have ever read . While I realize that the majority of people thought this to be a stellar book, it reminds me of the story, "The Emperor has no clothes".  Yes, Choan can write a beautiful sentence and yes, the first several pages were intriguing but the switching of years was very annoying.  The "flipping back and forth" was not accomplished in a smooth, flowing manner.  In addition, the subject matter was incredibly depressing and the characters were so flawed that one did not even care about how their lives evolved.  The kidnapping was predictable and the ending contrived.  It would be impossible to recommend this book to anyone

Ex Output:
NEG

An idiotic or deliberately misleading book - take your pick . I read this book in order to see if it would change my opinion about the status of social security. It does not. In fact, it glosses over the key, overriding issue: that the so-called "social security trust fund" does not in fact exist. The claim that huge surpluses are being mounted is meaningless when all that really exists is an IOU that the government writes to itself.     The book spends all of one paragraph (see page 28) on this critical issue, suggesting that the reader imagine that the fund is invested in private stocks and bonds, rather than government bonds, and concluding, "It is difficult to see why the composition of the trust fund's portfolio should make any difference." I just about threw the book across the room at that point! In other words, the authors see no difference between a fund backed by real assets that can simply be sold and a fund that will require raising taxes or additional borrowing on an enormous scale

Ex Output:
NEG

Ching's Architectural Graphics . This book is a great reference for architecture students and architects.  It shows in great detail drawing types and explains the uses for each of the types.  It is also very helpful at the beginning with explaining the tools for drawing and their uses.  I would recommend this book to anyone; it is a great tool for anyone in the field of design

Ex Output:

POS
