I am currently an associate professor in Beijing Institute of Technology (Director: Prof. Heyan Huang). Before, I obtained the bachelor degree and the master degree (Supervisor: Prof. Juanzi Li) from Tsinghua University (Beijing) in 2006 and 2008, respectively, and obtained the Ph. D degree (Supervisor: Prof. Irwin King and Prof. Michael R. Lyu) from the Chinese University of Hong Kong (Hong Kong, China) in 2011. I visited Microsoft Asia under the "Star Track" program (Collaboration Mentor: Chin-Yew Lin) in 2013. From the day I began to conduct research, my interests have been focused on probabilistic graphical models. Besides, in the era of LLM, I also guide my students on the topic of building knowledge graphs and encyclopedia entries, and I hope these work can be applied in educational scenarios.

2. Knowlege Graph and Encyclopedia Entry Generation
Semantic Parsing for Texts, Audios, and Images: To understand the semantic structure of these social media content.
Automatic Knowledge Graph and Encyclopedia Entry Construction: To convert Web data into structured knowledge graph data.
Fine-Grained Semantic Retrieval: To retrieval the information from the granularity of syntactic analysis.
Reliable Fact Inference: To conduct explainable LLM inference based on logic theories.
