2026-09-10 TibetanQA2.0: Dataset with Unanswerable Questions for Tibetan Machine Reading Comprehension doi:10.57760/sciencedb.j00104.00120 en This paper constructs the Dataset with Unanswerable Questions for Tibetan Machine Reading Comprehension (TibetanQA2.0). This dataset was constructed by crowdworkers, and contains 505 passages and 1,347 unanswerable question-and-answer pairs. The passages cover six topics, which are geography, biology, history, nature, culture, and medicine. The dataset’s quality was ensured by unifying the use of interrogative particles, correcting spelling and grammar errors, and verifying its compatibility with the Tibetan context. Meanwhile, we have also made public the 8,200 data for  TibetanQA in the second sheet of the TibetanQA2.0 file, named TibetanQA1.0.
