SDOH-NLI: a Dataset for Inferring Social Determinants of Health from Clinical Notes

no code implementations27 Oct 2023 Adam D. Lelkes, Eric Loreaux, Tal Schuster, Ming-Jun Chen, Alvin Rajkomar

We evaluate both "off-the-shelf" entailment models as well as models fine-tuned on our data, and highlight the ways in which our dataset appears more challenging than commonly used NLI datasets.

How Does Generative Retrieval Scale to Millions of Passages?

no code implementations19 May 2023 Ronak Pradeep, Kai Hui, Jai Gupta, Adam D. Lelkes, Honglei Zhuang, Jimmy Lin, Donald Metzler, Vinh Q. Tran

Popularized by the Differentiable Search Index, the emerging paradigm of generative retrieval re-frames the classic information retrieval problem into a sequence-to-sequence modeling task, forgoing external indices and encoding an entire document corpus within a single Transformer.

Quiz-Style Question Generation for News Stories

1 code implementation18 Feb 2021 Adam D. Lelkes, Vinh Q. Tran, Cong Yu

As a first step towards measuring news informedness at a scale, we study the problem of quiz-style multiple-choice question generation, which may be used to survey users about their knowledge of recent news.
