Abstract

The invention belongs to the field of software quality guarantee, and discloses a software defect module severity prediction method based on an ordered neural network. The method comprises the following steps that a version control system and a defect tracking system where a sample software project is located are mined, measurement and defect severity marking are conducted on a program module of the sample software project, and a sample data set is constructed; based on the sample data set, an ordered neural network model and a Bayesian hyper-parameter optimization method are adopted to obtaina software defect prediction model, namely, the ordered neural network model with optimal hyper-parameters; and the defect severity of the program module in the software project is predicted by adopting the software defect prediction model. Compared with a conventional software defect prediction method, the method for constructing the software defect prediction model has the advantages that software defect prediction can be performed, the severity of defects can be predicted, and the prediction accuracy is higher.

Description

technical field [0001] The invention belongs to the field of software quality assurance, in particular to a method for predicting the severity of software defect modules based on an ordered neural network. Background technique [0002] With the rapid development of information technology, the complexity of software is constantly increasing, and the scale of software is also increasing. The dependence on information technology makes the guarantee of software quality particularly important. Especially in some important fields, once the software system fails, it may bring huge losses. When there are some serious defects in the software system, it will lead to serious consequences such as software errors, function failures, and crashes. Therefore, realizing the detection of modules with higher severity in the software system in the early stage of software can reduce product production and maintenance costs, and enhance the competitiveness of enterprises. Therefore, the predicti...
