About Me

I’m a third-year graduate student in the Websoft research group, Nanjing University. My research interests include question answering (QA) and knowledge graph (KG). Currently, I mainly focus on knowledge base question answering (KBQA) with semantic parsing-based methods. I have also conducted some research about recommender systems. I’m a former research intern at MSRA.
