Generation, Reasoning and Rewriting in Natural Dialogue System

Prof. WANG Liwei

Natural Dialogue Systems, including recent eye-catching multimodal (vision + language) dialog systems, need a better understanding of utterances to generate reliable and meaningful language. In this talk, I will introduce several research works that my LaVi Lab (multimodal Language and Vision Lab) has done together with our collaborators in this area. In Particular, I will discuss those essential components in natural dialog systems, including controllable language generation, language reasoning, and utterance rewriting, published in recent top NLP and AI conferences.

Prof. WANG Liwei received his Ph.D. from the Computer Science Department at University of Illinois at Urbana Champaign (UIUC) in 2018. After that, he joined Tencent AI Lab, NLP group at Bellevue, US as a senior researcher, leading multiple projects in multimodal (language and vision) learning and NLP. In Dec 2020, Dr. Wang joined the Computer Science and Engineering Department at CUHK as an assistant professor. In the meanwhile, he is also serving as the Editorial Board of IJCV and program committee in top NLP conferences. Recently, his team won 2020 BAAI-JD Multimodal Dialogue Challenge and also the Referit3D CVPR 2021 challenge. The research goal of Prof. Wang’s LaVi Lab is to build multi-modal interactive AI systems that can not only understand and recreate the visual world but also communicate like human beings using natural language.
