Jing Liu(刘璟)

Principal Architect
Natural Language Processing Department at Baidu Inc.


I am a principal architect and a tech lead of deep question answering team at Baidu NLP since December 2017. Before that, I was a researcher at Microsoft Research Asia (MSRA) from September 2014 to December 2017. I obtained Ph.D. degree in computer science from Harbin Institute of Technology (HIT) under the supervision of Prof. Hsiao-Wuen Hon (MSRA), Prof. Ting Liu (HIT) and Dr. Chin-Yew Lin (MSRA) in September 2014. My research interests include question answering, information extraction and social computing.

  • Mar 2021: RocketQAv1[paper] was accepted by NAACL 2021.
  • Oct 2020: We proposed RocketQA [paper], an optimized training approach to dense passage retrieval for open-domain question answering. RocketQA achieved the 1st rank at the leaderboard of MSMARCO Passage Ranking Task. It was featured in zh-cn and en-us.
  • Aug 2020: Baidu, CCF (China Computer Federation) and CIPSC (Chinese Information Processing Society of China) jointly lunched the project of LUGE(千言)[portal], that is an open-source project of Chinese NLP benchmarks. Specifically, LUGE aims to provide researchers with various kinds of data sets and comprehensive evaluations, and promotes the progress of Chinese NLP technology. Currently, we have collected more than 20 NLP datasets for 7 tasks from the great contributors of 11 organizations. LUGE was featured in videos (zh-cn, en-us) and articles (zh-cn). If you are interested in LUGE, pls. contact me.
  • Apr 2020: We released a Chinese dataset namely DuReaderrobust [paper][data and code] towards evaluating the robustness of machine reading comprehension models. We hosted a shared task of DuReaderrobust [leaderboard] at 2020 Language and Intelligence Challenge, and there were more than 1,500 teams and more than 4,600 submissions in the shared task. The shared task was featured in zh-cn.
  • Nov 2019: Our proposed machine reading comprehension system D-NET [paper][code] was ranked at top 1 in the MRQA 2019 Shared Task, that tests if MRC systems can generalize beyond the datasets on which they were trained. D-NET was featured in zh-cn (1, 2) and en-us.
