About this dataset

34 extractive question-and-answer pairs built from 72 to 128 days, published by agritech.tnau.ac.in. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. 5 of the 34 pairs (14.7%) are explanatory questions and 29 restate a figure. 91.18% of rows pass the corpus quality gate.
