### Dataset Summary |
|
|
|
Stanford Question Answering Dataset (SQuAD) is a reading comprehension dataset, consisting of questions posed by crowdworkers on a set of Wikipedia articles, where the answer to every question is a segment of text, or span, from the corresponding reading passage, or the question might be unanswerable. |
|
|
|
SQuAD 2.0 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. |
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
Question Answering. |
|
|
|
### Languages |
|
|
|
English (`en`). |
