Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I bought a new laptop and wanted a new printer. This wone came highly recommended from the story. It worked great for three months (of course, the length of the warranty). It now only states "paper jam" and after hours of time on the phone and with the hints on the web, I am going out to buy a new printer - I would certainly not buy this one, again.
Output:
Negative
