As mobile has become a big part of our everyday life, it is important to investigate how to optimize users’ mobile interaction experience In this talk, I will describe my research on automatically optimizing mobile user interactions with data-driven approaches The talk focuses on my two approaches to address the deficiency in existing interactions: the first approach optimizes user interaction with faceted browsing by leveraging search log data, the second approach optimizes user interaction with security permission requests by leveraging mobile-appstore data Finally, I will conclude the talk with multiple lines of my future work in the intersections of data mining, information retrieval, security, mobile computing, and software engineering
