Example Input: If you believe people have an eternal soul, this book is not for you. If you believe death is the end physically and spiritually, and you want your child to believe that, maybe you will like this book. I found it not comforting at all, and not what I want my child to believe.
Example Output: Negative

Example Input: I am a country and western fan in Memphis. This new Sony product is great! I meam really great. I don't have to remember songs I hear on the radio anymore. Definitely worth the $19.99 I paid. Get one!
Example Output: Positive

Example Input: I love this tiny MP3 player. Very easy to use. If you do have any problems, their customer support is great. I had to download a driver to get it going and I also called about another problem. They talked me right through everything and it all works well. I bought it primarly for the purpose of using a speaker system with it so I can listen to music in my office instead of depending on the radio. The earphoes included were not the best, so I did purchase another pair for improved comfort. I have loaded a video and some photos on it as well as music. To add videos and pictures it is necessary to dowload free software from the Sansa site. I feel this is a great product and it was better than I expected with a very reasoable price.
Example Output:
Positive
