Teacher: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Solution: Positive
Reason: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

Now, solve this instance: This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!) My cat jumps right over it and I end up with litter kicked up all over the place. Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter. I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars. Hopefully, I'll have more success with that!
