Problems solved by technology

Not involved in function change prediction
(2) Existing graph mining technology needs to find out all frequent subgraphs, so the time overhead is particularly large
(3) Since the graph mining technology finds all frequent subgraphs, the amount of data is extremely large, which also brings great trouble to subsequent processing

Embodiment Construction

[0055] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0056] Before the description, the technologies and terms involved in the present invention will be explained.

[0057] Codeviz, graphviz, ctags, and sed are third-party tools under Linux. You can install them directly by entering the sudo apt-get install tool name command on the command line.

[0058] The cdepn file is a *.cdepn file with the corresponding name generated for the .c file under the source code file to be processed after using the installed codeviz and graphviz. The file format is as follows Figure 5 shown.

[0059] The Shell command is a command line editor that comes with Linux and is used to handle various common operations.

[0060] Such as figure 1 As shown, the present invention includes a function call relation graph generation module, a changed function call relation graph acquisition module, and a graph mining and changed f...

Abstract

The invention relates to a software function change prediction system and method based on graph mining and belongs to the field of software engineering. The system and method of the invention carry out calculation based on software network function call relational graphs; first, the whole function call relational graph is required to obtain; by comparing the functions of the adjacent versions, modified, deleted, added functions are get and a changed function subgraph is obtained; by means of the graph mining algorithm span, parameters are selected which are mainly span and support degree to obtain corresponding frequent subgraphs, wherein the functions contained in the subgraphs are predicted functions that can be changed.

Description

technical field [0001] The invention relates to a software function change prediction system and method based on graph mining, and belongs to the fields of complex network and data analysis and software engineering. Background technique [0002] Complex networks are often accompanied by the spread of information, viruses, diseases, etc., and the topology of a network has a significant impact on the degree of change propagation. In the field of computer science, class diagrams, dependency diagrams, relationship diagrams, software component diagrams, and function call diagrams in large software systems all belong to complex networks. [0003] When a developer modifies a part of the software system in order to add a new function or fix a bug, other parts often need to be updated in order to adapt to the modification. Quantifying the propagation of a software network can help save the overhead of software maintenance. [0004] In the function call diagram, change propagation i...
