Refactoring of code clones is one process of reducing code clones while maintaining external behavior. It is able to increase the software maintainability. When a company which is commissioned to maintain software has to estimate the cost and benefit of refactoring source code owned by a customer. They have trouble preparing their estimates because of refactoring code clones that have several problems is difficult. We proposed a solution to each problem and applied a method to investigate “the amount of reducible source code” for seven open source software products. As a result of the investigation, we found that approximately 6.9% of the detected code clones could be reduced.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1062","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1051","bibliographicIssueDates":{"bibliographicIssueDate":"2019-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"60"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"links":{},"id":195500,"updated":"2025-01-19T23:04:30.840519+00:00"}
