}

Data Fields

Each example in the dataset contains the unique Natural Questions example_id, the original English query, and then queries and answers in 26 languages. Each answer is labelled with an answer type. The breakdown is:

Answer Type	Occurrence
entity	4221
long_answer	1815
unanswerable	1427
date	1174
number	485
number_with_unit	394
short_phrase	346
binary	138

For each language, there can be more than one acceptable textual answer, in order to capture a variety of possible valid answers.
