Complex network based software structure important module recognition method

Abstract

The invention discloses a complex network based software structure important module recognition method which comprises the following steps of step 1, determining a target software, and acquiring an intact software source code of the target software; step 2, performing static scanning on the target software source code, and analyzing a relationship between an element entity and an element in the software; step 3, on the basis of the step 2, constructing a software attribute method network and a corresponding granularity software complex network model; and step 4, after obtaining the software complex network model in the step 3, obtaining a set of nodes ordered according to importance measures, and selecting an important module by combining with an actual engineering condition. The inventionprovides a method of recognizing the important module by integrating factors, having influences on the module importance, in four dimensions based on the complex network, the whole measurement analysis process can be realized in background and is established on a full automatic flow, and the maximum reduction of the labor and time costs is ensured.

Description

technical field [0001] The invention belongs to the field of complex software networks, and relates to a method for identifying key modules of a software system based on a software network model. Background technique [0002] With the continuous development of information technology, computer software has been widely used in all aspects of human life, and has made great contributions to the development of human society and economy and the progress of scientific research. The importance of software has risen sharply. At the same time, due to the increase in people's demand for software functions and the increasingly complex software application environment, the scale and complexity of software systems continue to grow, causing software engineers to spend 30% to 60% of their energy in the process of software maintenance. In terms of system understanding, it is difficult for them to effectively test and maintain the software system with limited time and cost, so software system...
