Abstract

The invention discloses a software bug report classification system and a classification method. The system comprises a training part and a test part. The training part comprises a data set acquisition module, a data reduction module and an unbalanced data set processing module. The test part comprises a bug report input module and a result classification output module. The main steps of the classification method include using a data reduction algorithm to process data, using an RSMOTE method to process an unbalanced data set, training a classifier with the obtained balanced data set, and integrating a plurality of trained classifiers with Choquet fuzzy integrals to classify the results of a bug report. The invention reduces the data scale on the sample dimension and the word dimension through the method of combining the feature selection and the instance selection, improves the recognition degree of the severity of the bug report by using the integrated training method based on Choquet fuzzy integrals, and avoids the uncertainty of random sampling at the same time.

Description

technical field [0001] The invention relates to a computer software testing method, in particular to a software bug report classification system and method. Background technique [0002] In the research on the automatic identification and classification technology of software bug report severity, there are currently two main challenges: one is the noise problem (the sample dimension and word dimension of the data are both high); the other is the data imbalance problem. When some researchers tried to solve the bug report classification problem, they proposed six filter-based feature ranking techniques for high-dimensional problems to reduce the number of available software evaluation criteria, such as combining feature selection algorithms with instance selection algorithms to reduce Bug dataset size and improve data quality. For the problem of data imbalance, the existing technology adopts the method of selecting the same number of bug reports in the training set and the te...
