Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the feature location method based on multi-source software data analysis includes the following steps:

[0024] Build a feature location model based on multi-source software data analysis: set a quaternion , where m is the final feature location result, and a, b, and c are obtained from three different data sources respectively. Extracted feature information.

[0025] The positioning method of feature information a is as follows: search the current software system through information retrieval technology, query the program code related to the current modification request in the source code of the current software system, and record the program code as feature information a.

[0026] Such as figure 2 Shown is a block diagram of the working principle of the information retrieval technology of the present invention. The spe...

Abstract

The invention discloses a feature localization method based on multi-source software data analysis in the technical field of software engineering, and aims to solve the technical problems that feature localization results are inaccurate and incomplete in the prior art. The method combines information retrieval technology, data mining technology and dynamic analysis technology to respectively perform feature localization on a current software system, a evoluting history library and executing tracks, and intersection calculation is performed on feature localization results by the three technologies to acquire final feature localization results, feature localization based on multi-source software data analysis is implemented, and better accurateness, complement and efficiency are provided; the three technologies are high in maturity, so that the method is easy to operate and implement. The method can be applied in feature localization in class hierarchy and method hierarchy, reality of the analysis can be combined, corresponding granularity hierarchy can be selected to perform feature localization, and a flexible selecting frame is provided for realistic multi granularity hierarchical feature location.

Description

technical field [0001] The invention relates to a feature location method, in particular to a feature location method based on multi-source software data analysis, and belongs to the technical field of software engineering. Background technique [0002] With the increasing dependence of the information society on software, users have higher and higher requirements for existing software systems, so it is necessary to continuously upgrade and maintain software systems, and these upgrade and maintenance modification requests are usually Call it a feature. In a software system, a feature can represent a function, which is defined according to the requirements and acceptability of developers and users. Software maintenance and evolution may include various modification activities, such as adding new functions, improving existing functions and fixing bugs. Determining where in the source code a known special function is located is called feature localization. The process of fea...
