Example Input: Racist Classist Megalomaniac Talks A Little About Heroin . After hearing some decent things about this book, I was surprised at just how uninteresting and often offensive of a read it turned out to be.  Marlowe is accurate in some of her depictions of heroin use in the East Village of New York and way off base in others.  I chalk this up to everyone's experiences being different (however, I certainly don't think a one-bag-a-day habit with weeks off in between makes her an authority on addiction by any stretch of the imagination).  What I don't understand is why she felt the need to go into such great detail about her rather boring life between her discussions of the dope world.  Most of her anecdotes had little to no bearing on the story she was trying to tell and were mind-numbingly dull.  I found her narrative to be very disjointed and incoherent.  But what I found most repugnant was her better-than-thou attitude towards those of a lower class or darker skin tone (e.g. assuming dark-skinned men who didn't think to aspire to become more than security guards must not have gotten support or affirmation in their homes growing up, like she did).  She herself says that she became interested in street-life and street people in order to increase her "coolness" factor.  Sure she dabbled in drug use and in the East Village culture, but that does not make her an authority, and she does not paint a very true portrait of either.  If you want a good portrayal of street life and heroin use from the inside, read Seth Morgan's Homeboy.  If you want elitist drivel, this book should do the trick
Example Output: NEG

Example Input: vampire Christopher . Christopher Byron's sensibility indicates that he is a small-minded, pathologically envious little weasle of a man, who tries to puff up his empty meaningless life by attempting to denigrate a great woman who has brought great beauty and grace to our culture.  Unless you're one of those nasty-spirited people who find glee in joining the pack of hyenas who hate powerful, brilliant, talented women because the light from great women's souls is too bright and reveals too vividly your pathetic life, avoid this book. Byron is simply a mean little vampire, trying to suck money and notoriety from the life blood of Martha.  Shame on John Wiley &amp; Sons for publishing this book
Example Output: NEG

Example Input: Excellent book - Helps design EAI wisely . Reading a design patterns book for me is interesting when I find that nugget of coolness, the rest of the time it is plain boring. However, this book really keeps it interesting for the most part and still drives home the design points particularly around EAI. I think it would make a great book for someone wanting to get into design patterns, which is important for anyone writing integration applications. Also, it is a good all-around reference book for the serious and seasoned Java programmer who needs to know how to design integration. I have GoF, and I refer to this book more often from a practical standpoint
Example Output:
