Task: Question Understanding
Input (English): A growing body of evidence shows that state-of-the-art models learn to exploit spurious statistical patterns in datasets BIBREF12, BIBREF13, BIBREF14, BIBREF15, BIBREF16, BIBREF17, instead of learning meaning in the flexible and generalizable way that humans do. Given this, human annotators—be they seasoned NLP researchers or non-experts—might easily be able to construct examples that expose model brittleness. 
 Question: What are the weaknesses found by non-expert annotators of current state-of-the-art NLI models?
Output (English): Extractive
