Abstract
Semantic matching is critical in many text applications, including paraphrase identification, information re-
trieval, and question answering. A variety of machine learning techniques have been developed for various
semantic matching tasks, referred to as “learning to match”. Recently, deep learning approaches have shown
their effectiveness in this area, and a number of methods have been proposed. In this talk, I will discuss the
deep solutions to semantic matching from the aspects of the word and the sentence. At the word-level matching,
I will discuss the distributed word representations that bridge the semantic gap between different words. At
the sentence-level matching, I will discuss the matching methods that capture the proximity and text matching
patterns. Potential applications and future directions of semantic text matching will also be discussed.

Bio
Dr. Jun Xu received his Ph.D. in Computesr Science from Nankai University, China, in 2006. After that, he
worked as an associate researcher, researcher, and senior researcher at Microsoft Research Asia and Huawei
Noah’s Ark Lab. In 2014, he joined Institute of Computing Technology, Chinese Academy of Sciences. Jun Xu’s
research interests focus on applying machine learning to information retrieval. He has about 40 papers at top
international journals and conferences, including TOIS, JMLR, SIGIR, WWW etc. He has also been active in
the research communities and severed or is serving the top conferences and journals. For example, in 2017, he
was the Senior PCs/Area Chairs of SIGIR ’17 and ACML 2017; PC members of KDD ’17, NIPS ’17, CIKM ’17,
and WSDM ’17; reviewers of TOIS, JMLR, and TKDE etc.
