Design Pattern Detection Using Source Code of Before Applying Design Patterns

We propose an approach of design pattern detection us- ing source-code of before the application of the design pat- tern. Our approach is able to distinguish different design patterns with similar structures, and help maintainers un- derstand the design of the program more accurately. More- over, our technique reveals when and where the target pat- tern has been applied. It is useful to assess what kinds of patterns increase what kinds of quality characteristics.
