Research Outline

Before I joined ICReDD, my research focused on developing text indexing and mining techniques on query autocompletion by utilizing large text corpus. Query autocompletion (QAC) is an interactive feature that assists users in formulating queries and saving keystrokes. Due to the convenience it brings to users, it has been adopted in many applications, such as Web search engines, integrated development environments (IDEs), and mobile devices. In my previous research, I studied several fundamental problems of QAC and deliver high quality suggestions in an efficient way.
