Software Defect

Our defect dataset, comes from PROMISErepository. This data refers to open-source Java systems such as ant, camel, ivy, jedit, log4j, lucene, poi, synapse, velocity and xerces. We selected these datasets since they have at least three consecutive releases (where release i was built before release i+1). This will allow us to build defect predictors based on the past data and then predict (test) defects on future version projects, which will be a more practical scenario.

本缺陷数据集源于PROMISE存储库。该数据涉及开源Java系统，如ant、camel、ivy、jedit、log4j、lucene、poi、synapse、velocity及xerces。我们选取这些数据集，因其至少包含三个连续的版本发布（其中版本i的构建先于版本i+1）。此举将允许我们基于历史数据构建缺陷预测器，进而对后续版本的项目进行缺陷预测（测试），这将是一种更具实用性的场景。
