Problems solved by technology

[0004] (1) Existing work mainly focuses on measuring the complexity of the code elements themselves, and lacks the measurement of the importance of code elements
[0005] (2) Existing work is mainly aimed at element-level measurement, which often measures local features of software, such as measuring a method or a class. There is a lack of work on software measurement from an overall perspective, let alone the importance of measuring software elements from an overall perspective sex work

Embodiment Construction

[0055] Below by embodiment and in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0056] A kind of software package importance measurement method based on weighted a index that the present invention proposes, concrete steps are as follows:

[0057] (1) Abstract the software source code written in the Java language into a feature dependency network FDN=(N f ,D f ). figure 1 Shown is a Java source code snippet. according to figure 1 Given the Java source code snippet, the corresponding FDN can be constructed (such as figure 2 As shown), the text on the side of the node is the name of the corresponding feature of the node (the name is composed of package name, class name, and feature name connected by "."). Among them, N f ={p1.classX.a(),p1.classX.v(),p1.classX.c(),p1.classX.b(),p2.classY.d(),p2.classZ.e(), p2.classZ.f(), p3.classL.g()} is a collection of feature nodes; D f ={(p1.classX.b(),p1.classX.a()),(p1...

Abstract

The invention discloses a software package importance measurement method based on a weighted a index. The method comprises the steps of abstracting software source codes compiled by the Java language into a feature dependence network in feature granularity; building a class dependence network based on the feature dependence network; building a package dependence network based on the class dependence network; computing the weighed h index of a node based on the package dependence network; computing the weighted cit index of the node based on the package dependence network; and computing the weighted a index of the node based on the weighted h index and the weighted cit index of the node, and using the weighted a index of the node as a measurement index for the importance of the package. According to the software package importance measurement method based on the weighted a index, the shortage that the prior art hardly relates to the importance measurement is covered, and the important significance is provided for understanding the software and improving the code maintenance efficiency.

Description

technical field [0001] The invention relates to a software package importance measurement method, in particular to a software package importance measurement method based on weighted a index. Background technique [0002] Computer software has penetrated into every aspect of our work and daily life, is changing and will continue to change our lives. With the development of software technology and the popularization of the Internet, people's dependence on software is increasing day by day, and the requirements for software quality are getting higher and higher. This has led to a surge in system scale and an increasingly complex software application environment, which increases the risk of software development and makes it difficult to effectively control software quality. [0003] At the same time, evolution is one of the essential attributes of software. Like living things, software systems must evolve continuously during their life cycle, otherwise they may be eliminated i...
