PKUNLP-ICLER

👋 Hi, We are PKUNLP-ICLER !

We are an active research group at Peking University, led by Prof. Baobao Chang. Our research interests include a wide range of topics in Natural Language Processing (NLP), such as large language models, multi-modal learning, semantic parsing and so on. We are also interested in applying NLP techniques to solve real-world problems.

Baobao Chang

Chang, Baobao is an associate professor in the School of Computer Science. He obtained his B.Sc. from Shanxi University in 1992, and Ph.D. from Peking University in 1999 respectively. His research interests include Computational Linguistics, Chinese Language Resource Engineering, Chinese Segmentation, Syntactic and Semantic Parsing.

Dr. Chang has published over 70 high quality academic papers in international conferences and Journals, including top-tier conferences such as ACL, EMNLP, COLING, SIGIR and IJCAI. He has served in the Program Committee of various international conferences including ACL, EMNLP, COLING etc. He is co-authors of two text books and teaching courses on Computational Linguistics. As one of key contributors to the Comprehensive Language Knowledge Base (CLKB) project, he was awarded the Second Class National Scientific & Technical Progress Prize of China in 2011 and the First Class Scientific & Technical Progress Prize of Ministry of Education of China in 2007. He is vice director of the key laboratory of Computational Linguistics (Peking University), Ministry of Education, China and member of both CIPSC (Chinese Information Processing Society of China) and CAAI (Chinese Association for Artificial Intelligence). He is also serving on the editorial board of the Journal of Chinese Information Processing.
