Abstract: Bugs are prevalent in software systems, and how to effectively manage bugs has been an important activity in the software development life cycle. For example, in software testing and maintenance phases, bug report repositories are used for filing bugs and tracking their status changes; when a bug occurs, automatic techniques can be employed to extract useful information from failure runs for developers to diagnose the bug. In this thesis, we study two specific problems in bug management: duplicate bug report retrieval and bug signature identification. In particular, we focus on how discriminative techniques can be applied to these two problems. For duplicate bug report retrieval, we propose two metrics to measure the similarity between bug reports, and optimize the metrics based on discriminative models. For bug signature identification, we propose a discriminative generator mining algorithm to discover succinct and inclusive bug signatures to facilitate debugging.
