Right for the Wrong Reasons: Diagnosing Syntactic Heuristics in Natural Language Inference ACL2019

In order to generate some sample whose premise is the sequence of the hypothesis but the semantic are different.

Exmaple:

{
     sentence1: I hope Tom can go to school.
     sentence2: Tom go to school.
     y: 0
}
