Helping developers to localize bugs (using bug reports) to the changeset that induced them. Changesets (or diffs) can be more useful for fixing bugs than static source code (e.g., methods or classes) as they encode the change that created the bug and include a (usually) meaningful message.

Changeset-Based Topic Modeling of Software Repositories

The standard approach to applying text retrieval models to code repositories is to train models on documents representing program elements. However, code changes lead to model obsolescence and to the need to retrain the model from the latest snapshot. To address this, we previously introduced an approach that trains a model on documents representing changesets from a repository and demonstrated its feasibility for feature location. In this paper, we expand our work by investigating: a second task (developer identification), the effects of including different changeset parts in the model, the repository characteristics that affect the accuracy of our approach, and the effects of the time invariance assumption on evaluation results.
