Span Selection Pre-training for Question Answering [article]

Michael Glass, Alfio Gliozzo, Rishav Chakravarti, Anthony Ferritto, Lin Pan, G P Shrivatsa Bhargav, Dinesh Garg, Avirup Sil
2020 arXiv   pre-print
Span Selection Pre-Training (SSPT) poses cloze-like training instances, but rather than draw the answer from the model's parameters, it is selected from a relevant passage.  ...  Specifically, our proposed model has strong empirical evidence as it obtains SOTA results on Natural Questions, a new benchmark MRC dataset, outperforming BERT-LARGE by 3 F1 points on short answer prediction  ...  Unlike other work, this did not use document structure but instead used a search index to retrieve a related passage for a given question.  ...

UNIQORN: Unified Question Answering over RDF Knowledge Graphs and Natural Language Text [article]

Soumajit Pramanik, Jesujoba Alabi, Rishiraj Saha Roy, Gerhard Weikum
2022 arXiv   pre-print
Question answering over knowledge graphs and other RDF data has been greatly advanced, with a number of good systems providing crisp answers for natural language questions or telegraphic queries.  ...  Some of these systems incorporate textual sources as additional evidence for the answering process, but cannot compute answers that are present in text alone.  ...  This is because reading comprehension (RC) QA systems search for the best answer span within a passage, and will not work well unless the passage matches the question tokens and contains the answer.  ...
