Abstract: Mining design patterns from source code is a very important technology for improving the intelligibility and maintainability of software.In this paper，a new matching method based on fuzzy is presented to mine design patterns.A matrix model is used to describe design patterns and source code as the basis of matching.Clustering method is adopted to optimize the source code model in order to improve the efficiency of matching.Combining fuzzy theory to patterns matching，this method introduces the static and dynamic information to enhance the accuracy of matching.Experimental results demonstrate the improvement of matching in accuracy and integrality，avoiding the invalidation for some special design patterns.
