Teacher:Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Teacher: Now, understand the problem? Solve this instance: Traveled to this hotel on a family vacation. We chose this hotel because it was pet friendly. Upon arrival we smelled just how pet friendly it was! The dog that greets you attacked my dog. There was constant barking throughout the night and during breakfast, I found hair in my eggs! I would not recommend this hotel!
