I am working on task-oriented dialogue systems in Meituan, which is China’s leading shopping platform for locally found consumer products and retail services. Before that, I graduated from Department of Automation, Tsinghua University with a bachelor’s degree, and from the Knowledge Computing Lab, Peking University with a Phd’s degree, advised by Prof.Ye Wei (叶蔚). My research interest includes event extraction and dialogue systems. I have published several papers at the top conferences including ACL, SIGIR, EMNLP, NAACL, CIKM, etc.
