Teacher: In this task, you are given Yelp reviews. The task is to classify a review as "POSITIVE" if the overall sentiment of the review is positive or as "NEGATIVE" if the overall sentiment of the review is negative.
Teacher: Now, understand the problem? If you are still confused, see the following example:
This is my go to place to get the best chicken Pad Thai! Also the price is super good, considering most places have high prices and poor quality. Love this place, its definitely a top 5 fav for take out.
Solution: POSITIVE
Reason: The overall sentiment of the review is positive. Hence, the label is 'POSITIVE'.

Now, solve this instance: Yep. That thing Erin said. Don't trust these people.
I was sold French doors two years ago with screened side doors. Even when I bought them I had expressed concerns about having dogs who could damage the screens and was reassured that with a lifetime warranty that there would be no problem replacing them under warranty. After months of back-and-forth calling, even having a representative come out and evaluate and reassure me that the parts would be ordered and installed, I'm now back to square one being told that I would be charged for a visit to evaluate and charged for any work and materials to be done. Finally I'm being referred to the original manufacturer so I guess I'm a lot luckier than Erin and that my manufacturer is still in business!
