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 KDD'2016 Best Paper Award (Applied Data Science Track).
