Example Input: I like that this little medium size dress is tropical, sexy and modest at the same time. Im a 36C and had good bust coverage-I wore a sports bra/t shirt bra and slipped out of the shoulder string straps and just tucked them in to the bra-worked great. Im 5'4 and the dress comes down to the top of my knees. It is so feminine with the big bow tie in the keyhole back. I have washed it and it did not shrink. I wore it to Hawaii with flats.
Example Output: positive

Example Input: I have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.
Example Output: positive

Example Input: An interesting book about the Norse Mythology, Gods and Goddesses of Greek Mythology and Egyptian Gods. This book has ignited my curiousity about those famous characters I had seen in various movies. Upon reading, it broadens my knowledge about the ancient Greeks beliefs. I want to know more those fascinating gods and goddesses stories to name a few the ever famous Helen of Troy, Zeus, Athena and Medusa. A good read.
Example Output:
positive
