Abstract

Software functionalities and behavior are accomplished by the cooperation of code artifacts. The understanding of this type of source code collaboration provides an important aid to the maint enance and evolution of legacy systems. However, the originalcollaboration design information is dispersed at the implementation level. The extraction of code artifacts’ collaborations and the roles is therefore an important support in legacy software comprehension and design reco very. In this paper, we present a novel approach to efficiently recover and analyze code collabor ations and semantic roles based on dynamic program analysis technique. We also demonstrate thesoftware tools that we have developed to support our approach and illustrate the viability of our ap proach in a case study.
