objective of this paper is to make analysis of legacy system's specifications efficient. The analysis is one of the most important activity in maintenance. In maintenance of legacy systems, it is one of the hardest activity because of no experts, incorrect documents, less readability of source codes and so on. A conventional technology extracts rules from source codes and visualizes them as decision tables. The technology makes the analysis efficient. However, It may make large-scale decision tables from large-scale source codes. We found that extracted rules have many redundancy items. Our technology eliminates them from the rules. This elimination technology can make smaller decision tables than the conventional technology does and makes the analysis more efficient than it does.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告ソフトウェア工学（SE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-03-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"35","bibliographicVolumeNumber":"2018-SE-198"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":186625,"updated":"2025-01-20T02:31:56.287389+00:00","links":{},"created":"2025-01-19T00:53:33.924881+00:00"}
