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: Although this game is great, I would give it a 4.5 stars if I could. First the good: Beautiful graphics (the scenery is almost like real), the campaign has a story (unlike some RTS games that have no campaign or story), skirmish mode is fun but sometimes too quick, great gameplay, and it runs nicely. The bad: The units are sometimes kind of dumb (they stand and do nothing sometimes when they are told to go somewhere), the unit graphics could have been a little more sharp, and there aren't many units (this is not really that bad but I would have liked more units; there are 9 different combat units for the Romans). Don't let the bad things sway you from buying the game. Unless you are a real critic than the bad things would make you very mad.
