Abstract: Recovery of software artifact traccability is an important part in the research area of software maintenance and reverse engineering. However, most of the existing research works on traceability recovery focus on traceability within single product version. Different from these existing works, this paper concentrated on recovery of traceability a- mong evolution information on different levels, i. c. change document level, configuration management level and imple- mentation code level. This kind of evolution traceability is essential for understanding software evolution and mainte- nance. We proposed a method for evolution traceability recovery by combining keyword-based retrieval and heuristic rules. We also reported our experimental study on the evolution process of an open-source software.
