Wanling CAI (蔡婉铃)
Ph.D. Candidate



Hi! I'm Wanling CAI. I am a Ph.D. Candidate at the Department of Computer Science, Hong Kong Baptist University (HKBU), under the supervision of . Prior to that, I received my B.Eng degree in Software Engineering from the College of Computer Science and Software Engineering, Shenzhen University (SZU), China, in 2018. During my undergraduate study, I undertook research on intelligent recommender systems, under the supervision of .

I am currently working on dialogue-based conversational recommender systems. I am particularly interested in optimizing the design of conversational recommender systems via studies of human-computer interaction and natural language processing.
