Package Level Software Refactoring Using A-KNN and Understand Tool

Software internal complexity is one of the challenging problems in software engineering. Enhancing, modifying or adapting the software to new requirements increases the internal software complexity. Software with high level of internal complexity is difficult to maintain. Software refactoring reduces software complexity and hence decreases the maintenance effort. However, software refactoring becomes quite challenging task as the software evolves. Clustering is used as pattern recognition technique to assist in software refactoring activities at the package level. Understand tool is used to differentiate the packages and classes present in open source system [1].
