Software defect report classification method fusing multivariate text information and report intention

Abstract

The invention discloses a software defect report classification method fusing multivariate text information and report intention, which comprises the following steps of: after a software defect report is submitted, storing information such as abstract, project, component, reporter and intention in a CSV file format; preprocessing the data in the CSV format through methods of standardization, marking, stop word removal and word drying; extracting text information features of the report abstract by using BERT, extracting other features of the report by using a TF-IDF method, including the intention of the report, and further generating a feature matrix; the feature matrix is normalized to form a training set, and the training set is respectively input into five classifiers, including K-NN, NB, LR, SVM and RF, for establishing a classification model; and selecting one classification model with the best performance from the five classification models to realize classification of defect reports. According to the method, text mining, natural language processing and machine learning technologies are combined, and reports are divided into error reports and non-error reports.

Description

technical field [0001] The invention relates to defect report classification technology, in particular to a software defect report classification method that combines multivariate text information and report intent. Background technique [0002] At present, as the main activity in the later maintenance stage of software engineering, defect repair has an important impact on software quality assurance. In recent years, with the vigorous development of the software engineering industry, the complexity of the architecture of the software system and the capacity of the code have reached a level that is difficult for developers to understand and manage. This trend has inevitably led to a large number of defects in the software system development process. In order for the system to run normally, it is very necessary to fix these defects. The most common aid that developers use when fixing bugs is the bug report. The defect report describes the defects in the software system in th...

Problems solved by technology

In addition, some scholars are concerned about the quality of defect reports and the imbalance of categories of data sets.

[0004] However, a large number of existing studies have not considered the reporting intent when classifying defect reports, which leads to the low performance of their methods.
