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: When one is trying to get a basic overall grasp of Greek mythology, it can be an overwhelming and formidable subject, and one can be at a loss for the best place to start. Most books I've found either give too much detail too fast or else are hit-and-miss selections that don't give a very comprehensive introduction. If that's been your experience too, this book could be an excellent solution to your problem. It gives a highly readable thorough introduction without overwhelming you with details. As an introduction to or review of Greek mythology, it is therefore highly recommendable. Although probably aimed primarily at children, I suppose grown-ups too, if not already expert on the subject, won't find it too elementary.
