• Abstract: Objectives Create a dataset for the development and evaluation of clinical question-answering (QA) systems that can handle multi-answer questions. Materials and Methods We leveraged the annotated relations from the 2018 National NLP Clinical Challenges (n2c2) corpus to generate a QA dataset. The 1-to-0 and 1-to-N drug-reason relations formed the unanswerable and multi-answer entries, which represent challenging scenarios lacking in the existing clinical QA datasets. Results The result RxWhyQA dataset contains 91,440 QA entries, of which half are unanswerable, and 21% (n=19,269) of the answerable ones require multiple answers. The dataset conforms to the community-vetted Stanford Question Answering Dataset (SQuAD) format. Discussion The RxWhyQA is useful for comparing different systems that need to handle the zero- and multi-answer challenges, demanding dual mitigation of both false positive and false negative answers. Conclusion We created and shared a clinical QA dataset with a focus on multi-answer questions to represent real-world scenarios.

  Question and answer generation (QAG) consists of generating a set of question-answer pairs given a context. In this paper, we establish baselines with three different QAG methodologies that leverage sequence-to-sequence language model (LM) fine-tuning. Experiments show that an end-to-end QAG model, which is computationally light at both training and inference times, is generally robust and outperforms other more convoluted approaches.

  We study the problem of realistic VQA (RVQA), where a model has to reject unanswerable questions (UQs) and answer answerable ones (AQs) We first point out 2 drawbacks in current RVQA research, where (1) datasets contain too many unchallenging UQs and (2) a large number of annotated UQs are required for training. We propose a new testing dataset, RGQA, which combines AQs from an existing VQA dataset with around 29K human-annotated UQs. This combines pseudo UQs obtained by randomly pairing images and questions, with an
