Research Fields:

Dr. Yanyan Lan has an excellent academic record. Her research fields are information retrieval and machine learning. During her time at Institute of Computing Technology, CAS, she headed the Department of Data Science, Key Lab of Network Data Science and Technology, and led the team in fundamental research information retrieval theories, computing paradigms, and interactive mechanisms. Her team’s research went beyond the basic theoretical hypothesis of information retrieval, built the Learning to Rank theory, and came up with a framework for relation-based Learning to Rank and a computing model for deep matching, which shifted information retrieval from a static ranking of results to a dynamic generation of information, greatly improving the utility of information retrieval. Dr. Yanyan Lan published 57 papers on top international conferences and periodicals ranked A-level by China Computer federation. Her H-index stands at 29 and her research has been cited 3800 times on Google cholar. She is the recipient of the Best Student Paper Award of SIGIR 2012 and the Best Paper RunnerUp Award of CIKM 2017, both top international conferences in the area of information retrieval. Her research in this area also won her Microsoft Fellowship, enrollment in Microsoft Star Track program, the title of Beijing Academy of Artificial Intelligence Young Scientist, and membership of CAS Youth Innovation Promotion Association.

Dr. Yanyan Lan’s academic services cover serving as a long-term (senior) PC member and reviewer for international academic conferences and journals. She was the Chair of SIGIR 2020 Summer School, Chair of CIKM 2020 Short Papers Program Committee, Chair of YSSNLP 2020. She is also a Senior Member of China Computer Federation (CCF), Executive Member of CCF Committee on Terminology, Member of CCF Women’s Committee; Deputy Director of Committee on Communications and Mathematics, China Society for Industrial and Applied Mathematics; Member of Committee on Machine Learning, Chinese Association for Artificial Intelligence; and Member of CIPSC Committee on Information Retrieval, Chinese Information Processing Society of China.

Dr. Yanyan Lan started supervising students in 2011 and has so far been supervisor to 2 master candidates and 5 doctoral candidates. Her graduate students now work in research institutes such as CAS Institute of Computing Technology and CAS Institute of Software, and Internet companies such as Baidu, Bytedance and JD.com. In 2015, Dr. Yanyan Lan opened machine learning courses at undergraduate and graduate levels in University of Chinese Academy of Science, and her courses have been popular with students ever since.
