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: Vista has been out for 4 years, I'm up to Windows 7, and they still haven't released a driver update for this scanner!This is what's called planned obsolescence, where they intentionally make something not work so that you have to buy the new version. There's no reason or excuse for Visioneer not to release an update.This was the last scanner I'll ever buy from Visioneer. How can I have any confidence that they won't do the same thing with their new scanners when I upgrade computers again?
