Software defect information, including links between bugs and committed changes, plays an
important role in software maintenance such as measuring quality and predicting defects …

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 …

Empirical studies of software defects rely on links between bug databases and program
code repositories. This linkage is typically based on bug-fixes identified in developer …

In software engineering experiments, the description of bug reports is typically treated as
natural language text, although it often contains stack traces, source code, and patches …

Bug-fixes are widely used for predicting bugs or finding risky parts of software. However, a
bug-fix does not contain information about the change that initially introduced a bug. Such …

To collect software bugs found by users, development teams often set up bug trackers using
systems such as Bugzilla. Developers would then fix some of the bugs and commit …

Nowadays, bugs have been common in most software systems. For large-scale software
projects, developers usually conduct software maintenance tasks by utilizing software …

Various information retrieval (IR) based techniques have been proposed recently to locate
bugs automatically at the file level. However, their usefulness is often compromised by the …

Bug deduplication, ie, recognizing bug reports that refer to the same problem, is a
challenging task in the software‐engineering life cycle. Researchers have proposed several …

Software crashes are severe manifestations of software bugs. Debugging crashing bugs is
tedious and time-consuming. Understanding software changes that induce a crashing bug …
