Abstract
The paper gives an overview of a Ph.D. thesis and describes the main contents of the thesis. The thesis makes research on reverse engineering of object-oriented software at source codes level. According to the dynamic property of object-oriented software system, a group of models, mechanisms and algorithms that can be used to extract dynamic information and abstract high-level models of such systems are provided in the thesis. A group of systematic experiments are also conducted in the thesis so as to verify the correctness, validity and other related performance of these dynamic model design recovery and architecture abstraction algorithms.
