Ex Input:
Ethnocentric and quite boring . I was so disappointed by this book I could not get through more than a couple of chapters.  The author may know about mountaineering, but he seems to know very little about Kenya.  Moreover, I found the writing to be ethnocentric and quite boring

Ex Output:
NEG


Ex Input:
Functional and Fun; The New Knitting Book . I LOVED this book. I picked it up on a whim and spent the next two hours reading and laughing. The patterns are fun and these girls are so funny. I think this is a great book to have in my library. It has several patterns that I really want to make as gifts and I think even the book would make a great gift to any knitter

Ex Output:
POS


Ex Input:
Somewhat dull and unsatisfying . Somewhat dull and unsatisfying, like some other "literary" works I've read which don't hole my interest, don't resolve problems, swimming endlessly in the inner thoughts of a person with no action or only references to previous actions. I enjoyed his 'They Came Like Swallows' because it was very satisfying, but this is too "literary" for me in the sense that it appears to be more about the writer's writing ability than the actual story.

Ex Output:

NEG
