Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To precisely determine, as a similar program, a program which has different sentence structure and data structure but has similar processing contents.SOLUTION: A model extracting unit 11 converts a source code into a model using syntax definition information. Then, a mode summarizing unit 13 converts the model into a summarized model by treating portions where the same instructions occur on the same data region in the model as a single command by using data region definition information. Then, a similarity calculating unit 15 calculates similarity between summarized models by using the summarized model. Then, a determination unit 17 determines whether or not a source code is similar by using the similarity of summarized models and outputs the determination result.SELECTED DRAWING: Figure 1
