A Comparison of Approaches to Legacy System Crosscutting Concerns Mining

Mining of crosscutting concerns is a process that crosscutting concerns are automated identified from code of legacy system. The mining of crosscutting concerns provides the possibility for aspect-oriented refactoring of legacy system. This paper compares and analyzes existing crosscutting concerns mining approaches by four aspects: dynamics, mining ranges, mining principle and mining level, and puts forward some future research directions.
