Abstract (in Japanese) (See Japanese page) 
(in English) Structure changes of source code including refactoring are inevitable activities in software development and maintenance, and also they are recommended for the improvements of maintainability. However, we can obtain only file-level and line-level change information from source code management systems. Therefore, it has been difficult to understand
structure changes including moving and renaming of classes or methods. As a result, management of changes will become cost of software development and maintenance, and developers might make bugs because of misunderstanding changes. This paper presents a technique of identifying systematic changes of Java souce code structure. For identifying systematic changes, the core part of analyzing source code structure changes is mapping elements between two revisions. Though previous work tackle this problem based on the similarity of subgraph, we obtain matching pairs based on the similarity of the content of elements. We report the result of empirical evaluation of our technique with nine open source software projects from Android and Eclipse.
