### Dataset Summary |
|
|
|
combines the 100,000 questions in SQuAD1.1 with over 50,000 unanswerable questions written adversarially by crowdworkers |
|
to look similar to answerable ones. To do well on SQuAD2.0, systems must not only answer questions when possible, but |
|
also determine when no answer is supported by the paragraph and abstain from answering. |
|
|
|
