... with the aim of remodularizing them [4, 54, 99]. Some of such features apply to Object Oriented software as well, and can be used to derive a package diagram from the source code of the classes ... issued inside the code of the classes under analysis. A concept consists of a set of classes performing a set of same method calls, which are not simultaneously made by the c...
