What is recorded here?
Created crowdsourced questions over Wikipedia paragraphs with text-span answers, then added deliberately plausible unanswerable questions to require systems to abstain when the passage lacks an answer.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
SQuAD 2.0 combines filtered SQuAD 1.1 examples with new negative questions; it is not an independently authored replacement corpus. Answerability is defined relative to the supplied passage. Span overlap or abstention performance is not universal truthfulness or calibrated uncertainty.
