Topic-based, time-aware bug assignment
Tung Thanh Nguyen, Anh Tuan Nguyen, Tien N. Nguyen · ACM SIGSOFT Software Engineering Notes · 2014
Bugs are prevalent in software systems and improving time efficiency in bug fixing is desired. We performed an analysis on 11,115 bug records of Eclipse JDT and found that bug resolution time is log-normally distributed and varies across fixers, technical topics, and bug severity levels. We then propose FixTime, a novel method for bug assignment. The key of FixTime is a topicbased, log-normal regression model for predicting defect resolution time on which FixTime is based to make fixing assignment recommendations. Preliminary results suggest that FixTime has higher prediction accuracy than existing approaches.
