基于半监督文本分类的漏洞自动分类

Automatic Bug Triage using Semi-Supervised Text Classification

Jifeng Xuan, He Jiang, Zhilei Ren, Jun Yan, Zhongxuan Luo

摘要:

针对现有有监督文本分类方法中标注错误报告的不足,提出了一种半监督文本分类方法。这种新方法结合了朴素贝叶斯分类器和期望最大化,以利用标记和未标记的错误报告。这种方法用一小部分标记的bug报告来训练分类器。然后,该方法迭代地标记大量未标记的错误报告,并训练一个新的分类器与所有的错误报告的标签。我们还采用了一个加权推荐列表,通过在训练分类器时施加多个开发人员的权重来提高性能。Eclipse的错误报告的实验结果表明,我们的新方法优于现有的监督方法的分类精度。

英文摘要:

In this paper, we propose a semi-supervised text classification approach for bug triage to avoid the deficiency of labeled bug reports in existing supervised approaches. This new approach combines naive Bayes classifier and expectation-maximization to take advantage of both labeled and unlabeled bug reports. This approach trains a classifier with a fraction of labeled bug reports. Then the approach iteratively labels numerous unlabeled bug reports and trains a new classifier with labels of all the bug reports. We also employ a weighted recommendation list to boost the performance by imposing the weights of multiple developers in training the classifier. Experimental results on bug reports of Eclipse show that our new approach outperforms existing supervised approaches in terms of classification accuracy.
