Tool for Improved Software Bug Localization

Summary

Purdue University researchers have developed an algorithm that can significantly narrow down the portion of the software that must be examined to create a bug fix. The method mines the version histories of the software artifacts created incrementally during software development. It employs a novel Information Retrieval framework that leverages the relative importance of each incremental change of the software to a given bug using the change's associated time stamp in the repository logs. This method has been shown to greatly improve bug localization accuracy.
