Research

Before June 2021, my primary focus was on Chinese macro discourse parsing. Since then, I have shifted my attention to dialogue discourse parsing and actively explored applying discourse structures to downstream tasks, such as multi-party dialogue generation. Additionally, I have closely collaborated with partners on topic shift detection, query rewriting, proactive dialogue, and applications of LLMs. Currently, my main focus is on leveraging LLMs to enhance dialogue discourse parsing.
