摘要：

When designing a new application, experienced software engineers usually adopt solutions that have proven successful in previous projects. Such reuse of code organizations is seldom made explicit. Nevertheless, it represents important information, which can be extremely valuable in the maintenance phase by documenting the design choices underlying the implementation. In addition it can be reused whenever a similar problem is encountered. In this paper an approach for the inference of recurrent design patterns directly from the code is proposed. No assumption is made on the availability of any pattern library, and the concept analysis algorithm—adapted for this purpose—is able to infer the presence of class groups which instantiate a common, repeated pattern. In fact, concept analysis provides sets of objects sharing attributes, which—in the case of object-oriented design patterns—become class members or inter-class relations. The approach was applied to three C+
