Natural Language Processing Team

Leader: Weiguang Qu
Members: Junsheng Zhou, Yanhui Gu,Yi Zeng


Introduction:
The group of “Natural Language Processing” focuses mainly on machine learning based natural language processing, web information extraction and Question-Answer system. Recently, this group pays particular attention to semantic parsing (i.e. Abstract Meaning Presentation (AMR) parsing) for both English and Chinese, deep learning algorithms, as well as their applications. These studies relate to an interdisciplinary field between artificial intelligence and linguistics. This group consists of 2 professors and 1 associate professor. In the recent 5 year, this group published more than 30 papers including the publishing in the top ranked international conferences, and more than 4 NSFC projects have been granted.
