题目: Modeling User Engagement for Ad and Search
演讲者: Ke(Adam) Zhou
In the online world, user engagement is a key concept in designing user-centered web applications. It refers to the quality of the user experience that emphasizes the phenomena associated with wanting to use an application longer and frequently.
In this talk, I will present my past efforts in modeling user engagement in the context of ad and search, seeking to provide insights on how to make an engaging experience. Firstly, to ensure long-term user engagement with Yahoo, I will present a learning framework that effectively identify ads with low quality. Secondly, in the context of search, I will talk about understanding and modeling user examination and satisfaction of the search result pages.
