One note on the scope of the grant above, stated because it is the first thing
a careful reader will check.

The `context` column is Thai Wikipedia article text. It is not ours and the MIT
grant above does not reach it. Wikipedia text is licensed under Creative
Commons Attribution-ShareAlike — CC BY-SA 3.0 Unported when these articles were
collected in 2019, and CC BY-SA 4.0 since the Wikimedia projects relicensed in
2023. Attribution to Thai Wikipedia is owed by anyone redistributing this data,
and share-alike attaches to a redistributed derivative of that text regardless
of what we license our own contribution as.

What the MIT grant does cover is iApp's contribution: the questions, the answer
spans, the annotation work behind them, and the assembly of all of it into
SQuAD format.
