_DESCRIPTION = r"""\
SquadShifts consists of four new test sets for the Stanford Question Answering \
Dataset (SQuAD) from four different domains: Wikipedia articles, New York \
Times articles, Reddit comments, and Amazon product reviews. Each dataset \
was generated using the same data generating pipeline, Amazon Mechanical \
Turk interface, and data cleaning code as the original SQuAD v1.1 dataset. \
The "new-wikipedia" dataset measures overfitting on the original SQuAD v1.1 \
dataset. The "new-york-times", "reddit", and "amazon" datasets measure \
robustness to natural distribution shifts. We encourage SQuAD model developers \
to also evaluate their methods on these new datasets! \
