An Approach to Improving Bug Assignment with Bug Tossing Graphs and Bug Similarities

In open-source software development a new bug firstly is found by developers or users. Then the bug is described as a bug report, which is submitted to a bug repository. Finally the bug triager checks the bug report and typically assigns a developer to fix the bug. The assignment process is time-consuming and error-prone. Furthermore, a large number of bug reports are tossed (reassigned) to other developers, which increases bug-fix time. In order to quickly identify the fixer to bug reports the authors present an approach based on the bug tossing history and textual similarities between bug reports.
