Title: Fighting Software Bugs Through Automatic Text Analytics

Abstract: Software bugs greatly hurt software reliability. In this talk, I will present our recent research on leveraging software textual information in program comments, source code and bug reports to automatically detect and fix software bugs as well as understand software developers. iComment and aComment automatically extract specifications from source code and code comments written in a natural language, and use these specifications to detect comment-code inconsistencies, i.e., software bugs and bad comments. R2Fix automatically generates bug-fixing patches from bug reports written free-form in a natural language. We show that it is feasible to automatically analyze free-form comments and bug reports to automatically detect and fix software bug.
