Hi, I'm Longxu, a third-year Ph.D. student from Language Analysis Group of SCIR Lab in HIT. My research focuses on improving the parsing system in NLP. Currently, I am working on Text-to-SQL. I am fortunately advised by Professor Wanxiang Che. Previously, I have spent my wonderful undergraduate research life in MSRA, working with Jinpeng Wang, mentored by Chin-Yew Lin. Thanks to the support of my research mentors. I am fortunate to work with talented researchers and excellent classmates. Email: lxdou@ir.hit.edu.cn [Github] [Google Scholar]
