Bug Prioritization Using Average One Dependence Estimator

Abstract

Automation software need to be continuously updated by addressing software bugs contained in their repositories. However, bugs have different levels of importance; hence, it is essential to prioritize bug reports based on their sever-ity and importance. Manually managing the deluge of incoming bug reports faces time and resource constraints from the development team and delays the resolu-tion of critical bugs. Therefore, bug report prioritization is vital. This study pro-poses a new model for bug prioritization based on average one dependence estimator; it prioritizes bug reports based on severity, which is determined by the number of attributes. The more the number of attributes, the more the severity. The proposed model is evaluated using precision, recall, F1-Score, accuracy, G -Measure, and Matthew's correlation coefficient. Results of the proposed model are compared with those of the support vector machine (SVM) and Naive Bayes (NB) models. Eclipse and Mozilla datasetswere used as the sources of bug reports. The proposed model improved the bug repository management and out-performed the SVM and NB models. Additionally, the proposed model used a weaker attribute independence supposition than the former models, thereby improving prediction accuracy with minimal computational cost.
