Tie-Yan Liu


Tie-Yan Liu is a senior researcher and research manager at Microsoft Research Asia. His research interests include machine learning (learning to rank, online learning, deep learning, and statistical learning theory), information retrieval, and algorithmic game theory. He is well known for his pioneer work on learning to rank for information retrieval. He has authored the first book in this area, and published tens of impactful papers on both algorithms and theorems of learning to rank (with over 5000 citations in the past few years). He has also published extensively on other related topics. In particular, his paper on graph mining won the best student paper award of SIGIR (2008); his paper on video shot boundary detection won the most cited paper award of the Journal of Visual Communication and Image Representation (2004-2006); and his work on Internet economics won the research break-through award of Microsoft Research Asia (2012). Tie-Yan is very active in serving the research community. He is a program committee co-chair of ACML (2015), WINE (2014), AIRS (2013), and RIAO (2010), a local co-chair of ICML 2014, a tutorial co-chair of SIGIR (2016) and WWW (2014), a doctorial consortium co-chair of WSDM (2015), a demo/exhibit co-chair of KDD (2012), and an area/track chair of many conferences including ACML (2014), SIGIR (2008-2011), AIRS (2009-2011), and WWW (2011, 2015). He is an associate editor of ACM Transactions on Information System (TOIS), an editorial board member of Information Retrieval Journal (IRJ) and Foundations and Trends in Information Retrieval (FnTIR). He is a keynote speaker at ECML/PKDD (2014), CCIR (2011, 2014), CCML (2013), and PCM (2010), a tutorial speaker at SIGIR (2008, 2010, 2012), WWW (2008, 2009, 2011), and KDD (2012), and a plenary panelist at KDD (2011). He is a senior member of the IEEE, the ACM, and the CCF. He is currently an adjunct professor/Ph.D. supervisor of the Nankai University, the University of Science and Technology of China, and the Sun Yat-Sen University; and an Honorary Professor of the University of Nottingham.
