Multi-layered approach for recovering links between bug reports and fixes
Abstract
The links between the bug reports in an issue-tracking system and the corresponding fixing changes in a version repository are not often recorded by developers. Such linking information is crucial for research in mining software repositories in measuring software defects and maintenance efforts. However, the state-of-the-art bug-to-fix link recovery approaches still rely much on textual matching between bug reports and commit/change logs and cannot handle well the cases where their contents are not textually similar.
