Ex Input:
Knocked-up Ebony Mamas . Wittgenstein said that the purpose of a popularization is to make people think they understand something they don't understand. What seems to be a common current of science popularizations is that they "explain" things in such a simplified way that the reader who actually wants to get down to brass tacks is completely mystified. Einstein's book on relativity is a case in point, as is this book in which the candid reader is informed that "Objects at rest tend to remain at rest, therefore heavier objects will fall faster in a gravitational field." Got that? If so, maybe you can explain it to me. Listen, I know something about Physics. Back in the seventies I built a particle accelerator out of a blow drier and a box of Mike and Ikes.

Ex Output:
NEG

Ex Input:
A slippery, shoddy, and dishonest book . This is one of the very worst books on law and legal theory I have ever read. The authors deliberately confuse important issues, libel those with whom they disagree, and string together a series of logical fallacies in order to reach a set of conclusions they favor for other reasons. Readers who waste their time on this book will learn nothing of law and -- strikingly -- less than nothing of legal philosophy

Ex Output:
NEG

Ex Input:
Difficult to start, difficult to put down . I had this book on my shelf for a while before I cracked it open, knowing nothing about it except the synopsis on the back and that it came recomended from another book. The author goes into slight tangents of historical events -- at the beginning it seems pointless. After a while, you understand all the links, and begin to become very interested in this character that is much like many careless intellectual college drop outs who never found it fullfilling and always found themselves bound by the system. Maybe I liked it because I identified with her -- almost too much -- even though she is far richer and always seeking to put herself in a situation most level headed people wouldn't. That's what makes her facinating. In hind sight, I can see why many people didn't like it, but reading it, I was devoured by her smart writing style and the storyline. Not until 3/4ths into the book you suspect anything out of the ordinary. Suspensful, definately. The last chapter was kind of anticlimactic.

Ex Output:
POS
