BUTTER:一种基于主题模型和异构网络的缺陷分发方法

BUTTER: An Approach to Bug Triage with Topic Modeling and Heterogeneous Network Analysis

当软件缺陷被提交到缺陷跟踪系统并经过确认之后,它会被分发给开发人员进行缺陷修复.这个过程就叫做缺陷分发.随着被提交到系统的缺陷报告日益增多,手工分发缺陷报告会变得越来越困难.提出了一种自动分发缺陷的方法 BUTTER.与其他方法不同的是,BUTTER不仅利用主题模型分析缺陷报告中的文本信息,而且创新性地建立了一个包含提交者、缺陷和开发者三种节点及其相互关系的异构网络,从该异构网络中抽取了更多的结构信息.实验证明,BUTTER进行自动缺陷分发较其他缺陷自动分发方法要好.

When a bug was reported to the bug tracking system, it should be assigned to a developer who is responsible for its resolution after it is conftrrned. This processing is called bug triage. With increasing number of bug reports submitted to the bug tracking system, it is more and more difficult to assign appropriate developers to the reported bugs manually. In this paper, we propose an approach called BUTTER （BUg Triage by topic modeling and heTERogeneous network analysis） to automatically assign bugs to developers. Different from existing work, BUTTER not only uses topic model to analyze the text information from bug reports, but also innovatively takes structural information into consideration by constructing a heterogeneous network which includes relationships among submitters, bugs and developers. Experiment shows that BUTTER outperforms other methods on automated bug triage.
