All Data on the Table: Novel Dataset and Benchmark for Cross-Modality Scientific Information Extraction

no code implementations14 Nov 2023 Yuhan Li, Jian Wu, Zhiwei Yu, Börje F. Karlsson, Wei Shen, Manabu Okumura, Chin-Yew Lin

To close this gap in data availability and enable cross-modality IE, while alleviating labeling costs, we propose a semi-supervised pipeline for annotating entities in text, as well as entities and relations in tables, in an iterative procedure.

Distributional Shift-Aware Off-Policy Interval Estimation: A Unified Error Quantification Framework

no code implementations23 Sep 2023 Wenzhuo Zhou, Yuhan Li, Ruoqing Zhu, Annie Qu

This task faces two primary challenges: providing a comprehensive and rigorous error quantification in CI estimation, and addressing the distributional shift that results from discrepancies between the distribution induced by the target policy and the offline data-generating process.
