Example Input: Not as good as "Women on Top" . While the book was plentiful of wild, sensual fantasies, I was disappointed in some of them. Many were hard to believe even for fantasies and many sounded like they were written by illiterates. If you're looking for this type of book, I strongly recommend "Women on Top"
Example Output: NEG

Example Input: Athena and Kain: The True Meaning of Greek Myth . The preface to ATHENA and KAIN states that the content of the book is revolutionary, and it really is. I looked up revolutionary, and in the context used it means, "a total or radical change, as a revolution of thought." There is no other book on Greek art or myth like ATHENA and KAIN. Mr. Johnson points out that Greek sculptures appeared on public temples and other public buildings, and that mythological scenes appeared on the ancient Greeks' everyday pottery and storage jars. The average Greeks understood the meaning of their myths. Because of ATHENA and KAIN, it is now possible for us to understand them, too
Example Output: POS
