+  This metric wrap the official scoring script for version 2 of the Stanford Question Answering Dataset (SQuAD).
+
+  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.
+
+  SQuAD2.0 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.
