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 was a pretty good product until the damn thing just stopped working and just froze up when you tried to turn it on. I had it just over a year and after turning it on the device just went into bootup mode, never actually coming on. As long as I had it, it would frequently exhibit the same behavior. The only thing that would help was to take out the battery out and back in. Finally in the end, that did not help at all.The durability of the Sansa's line is poor at best.
