Abstract For a substantial improvement of the reengineering task, identifying the general and recurring high level concepts burried in the source code is essential. However, revealing such software patterns cannot be performed by automatic means only, it requires the management of various uncertainty issues. This paper introduces these patterns and discusses how the uncertainty issues arising during re-engineering can be handled. Furthermore, the paper shows the potential of high-level application patterns for improving the COREM re-engineering methodology.
