clone is a duplicate code fragment in the source code of software, and usually generated when developer conducts copy-and-paste. Since reuse of code fragment by copy-and-paste is considered to be a possible reason of introducing or spreading defects, methods of code review based on code clone analysis have been proposed by several previous researches. Although most of them can detect only the defect within cloned code fragment, it is necessary for developers to review both cloned and non-cloned code fragments because clone related defects might exist in non-cloned code fragment as well. However, there is no clarification regarding the tendency of defect occurrence within cloned code fragment or non-cloned code fragment. Moreover, method of code review for efficiently detecting defects in non-cloned fragment has not been established yet. For addressing these issues, this research quantitatively investigated the tendency of defect occurrence within cloned code fragment or non-cloned code fragment based on the positional relationship between code clone and code fragment by using development histories of open source software. The investigation result shows that defects tend to be involved in code fragments neighboring code clones.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"693","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"681","bibliographicIssueDates":{"bibliographicIssueDate":"2016-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":148210,"updated":"2025-01-20T17:21:29.280248+00:00","links":{},"created":"2025-01-19T00:23:13.709144+00:00"}
