  1. Towards End-to-End Reinforcement Learning of Dialogue Agents for Information Access

    2017

    Bhuwan Dhingra, Lihong Li, Xiujun Li, Jianfeng Gao, Yun-Nung Chen, Faisal Ahmed, Li Deng. Proceedings of the 55th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers). 2017.

  2. ASQA: Factoid Questions Meet Long-Form Answers

    2022

    Recent progress on open domain factoid question answering (QA) does not easily transfer to the task of long-form QA, where the goal is to answer questions that require in-depth explanations. The hurdles include a lack …

  3. Salient Span Masking for Temporal Understanding

    2023

    Salient Span Masking (SSM) has shown itself to be an effective strategy to improve closed-book question answering performance. SSM extends general masked language model pretraining by creating additional unsupervised training sentences that mask a single …

  4. Quasar: Datasets for Question Answering by Search and Reading

    2017 · arXiv (Cornell University)

    We present two new large-scale datasets aimed at evaluating systems designed to comprehend a natural language query and extract its answer from a large corpus of text. The Quasar-S dataset consists of 37000 cloze-style (fill-in-the-gap) …

  5. Open Domain Question Answering Using Early Fusion of Knowledge Bases and Text

    2018

    Open Domain Question Answering (QA) is evolving from complex pipelined systems to end-to-end deep neural networks. Specialized neural models have been developed for extracting answers from either text alone or Knowledge Bases (KBs) alone. In …

  6. Probing Biomedical Embeddings from Language Models

    2019

    Contextualized word embeddings derived from pre-trained language models (LMs) show significant improvements on downstream NLP tasks. Pre-training on domain-specific corpora, such as biomedical articles, further improves their performance. In this paper, we conduct probing experiments …

  7. PubMedQA: A Dataset for Biomedical Research Question Answering

    2019

    Qiao Jin, Bhuwan Dhingra, Zhengping Liu, William Cohen, Xinghua Lu. Proceedings of the 2019 Conference on Empirical Methods in Natural Language Processing and the 9th International Joint Conference on Natural Language Processing (EMNLP-IJCNLP). 2019.
