Relevance Ranking for Search Engines

Prof. Yi Chang
Dean
School of Artificial Intelligence
Jilin University
China

Date: January 29, 2019 (Tuesday)
Time: 10:30 - 11:30 am
Venue: SCT909, Cha Chi Ming Science Tower, Ho Sin Hang Campus

Abstract
Relevance ranking of search engine is a billion-dollar challenge, while there is a disadvantage of backwardness in web search competition. Learning to rank algorithms could effectively improve relevance ranking, yet it is a systematic effort to continuously improve the relevance of a search engine. In this talk, I will introduce the background and the most recent advances in this topic, in particular, three key techniques: ranking functions, semantic matching features and query rewriting. The major part of this talk is based on our ACM KDD'2016 Best Paper Award.
