I am a Lecturer at College of Liberal Arts, Shanghai University. I finished my Ph.D. journey at Tsinghua University. My research topic is computational linguistics, which combines natural languages and computer science. One epistemic problem I am trying to figure out is "What does the machine (model) know and does not know about human languages"? (Issues as E.M.B. proposed). Also, a bidirectional ball always bouncing in my mind - AI for linguistics and linguistics for AI.
