A Dataset for a Long-lived Prediction in FLOSS

We have created this dataset to support the research on the long-lived bugs. It stores a set of bug reports opened and closed during the last seven years, extracted from six popular Free/Libre Open Source Software (FLOSS) projects: Eclipse, Freedesktop, GCC, Gnome, Mozilla, and WinHQ. The researchers can explore bug data in this dataset to understand different questions on bugs' nature. For instance, they can use it to correlate the bug fixing time with bug characteristics. The attributes in our dataset are described in the attached README.md file.本数据集专为支持长生命周期缺陷（long-lived bugs）相关研究而构建。其收录了从6个主流自由及开放源代码软件（Free/Libre Open Source Software，FLOSS）项目中提取的、过去七年间提交并已关闭的缺陷报告，涉及项目包括Eclipse、Freedesktop、GCC、Gnome、Mozilla及WinHQ。研究人员可借助本数据集的缺陷数据，探究有关缺陷本质的各类研究问题；例如，可利用该数据集分析缺陷修复时长与缺陷特征之间的关联关系。本数据集的字段属性详情已在附带的README.md文件中予以说明。
