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: I switched to this food from Blue Buffalo. I hate to say it, but around the time Blue started doing tv commercials the food started upsetting my dog's stomach. Perhaps that's a coincidence, but it was a reason to switch regardless of the timing. The Newman's food has been great. My dog loves the food. He has been energetic and in great health. Not much more that you could ask. The bag of treats that comes in the 12.5 lb bag is a fantastic bonus to every bag.
