|Time:||2:00 pm - 3:00 pm|
|Venue:||Room 121, 1/F, Ho Sin-hang Engineering Building, The Chinese University of Hong Kong, Shatin, N.T.|
|Speaker:|| Prof. Yi CHANG
School of Artificial Intelligence
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.
Prof. Yi Chang is the Dean of the newly built School of Artificial Intelligence, Jilin University, where is actively looking for tenure-track faculty candidates at different levels. He was a Technical Vice President at Huawei Research America from 2016 to 2018, where he was in charge of knowledge graph, question answering and vertical search technologies within Huawei. Before that, he was a research director at Yahoo Research from 2006 to 2016, and in charge of relevance of Yahoo’s web search engine and vertical search engines. He has broad research interests on information retrieval, data mining and artificial intelligence. He has published more than 100 research papers in premium conferences or journals, and received the Best Paper Award on ACM WSDM'2016, the Best Paper Award on ACM KDD'2016 separately. He has actively involved in multiple academia services: he successfully chaired ACM WSDM'2018, and he will chair SIGIR'2020 in Xi'An, China. He was elected as an ACM Distinguished Scientist, due to his contributions to intelligent algorithms for search engines.
