What does BERT Learn from Multiple-Choice Reading Comprehension Datasets?

no code implementations28 Oct 2019 Chenglei Si, Shuohang Wang, Min-Yen Kan, Jing Jiang

Based on our experiments on the 5 key MCRC datasets - RACE, MCTest, MCScript, MCScript2. 0, DREAM - we observe that 1) fine-tuned BERT mainly learns how keywords lead to correct prediction, instead of learning semantic understanding and reasoning; and 2) BERT does not need correct syntactic information to solve the task; 3) there exists artifacts in these datasets such that they can be solved even without the full context.
