Abstract:

The program slicing can extract all statements which affect the value of the variable concerned.The program slicing is divided into fine-grained slicing and coarse-grained slicing.The Coupling Metrics based on the program slicing can estimate the total amount of information flow,and therefore are more accurate than those who only check whether the information flow exists or not.The slice-based coupling metric algorithm is improved with better accuracy in this paper.

Key words: program slicing;coupling metrics;information flow
