SOURCE CODE COMPARISON DEVICE, SOURCE CODE COMPARISON METHOD AND SOURCE CODE COMPARISON PROGRAM

A source code comparison device includes a difference extraction portion extracting a difference between a source code before correction and the source code after correction, a syntax analysis portion dividing the extracted difference into divided differences which are portions corresponding to components usable in the source code, and generating a syntax analysis result having associated the divided difference with the component corresponding to the divided difference, a feature analysis portion setting a feature division for each of the divided differences included in the syntax analysis result, and an output portion outputting a comparison result having associated the divided difference with the feature division set for the divided difference. The feature analysis portion sets the feature division associated with the component in a correction history for the divided difference associated with the component in the syntax analysis result.
