Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: This volume is a compilation of ballads taken from albums Joe Henderson recorded in the period 1992 to 1997. The music is supurb - Henderson almost whispers through his saxophone - and provides the perfect setting for a pleasant evening. Those who seek a late night CD look no further! Those who wish to explore Henderson's work of the nineties in more detail should consider buying (one of) the albums used for this compilation: "Lush Life", "So Near, So Far", "Double Rainbow", or "Porgy & Bess".
