We follow the methods using Factor Analysis (FA) proposed by Bergman and others. We use the three Input-output tables of the two prefectures Yamaguchi-ken and Tottori-ken and the Chugoku area in Japan and prepare the production coefficient matrix and the linkage matrix from each of the IO tables. We apply NMF and FA to those two kinds of matrices to get clusters of the area and compare the results. We found that for the linkage matrices, NMF and FA produce very similar results and that for production coefficient matrices, they produce different results. We investigate the reasons for these similarities and differences and conclude that NMF and FA (and other methods) can complement each other and NMF can take advantage of its features if it is applied to raw data or simple coefficient matrices of IO tables.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産大学校","subitem_publisher_language":"ja"},{"subitem_publisher":"National Fisheries University","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fishu_k_64_227","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"agriknowledge"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010922151","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00124678","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0370-9361","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Kajitori, Kazuaki","creatorNameLang":"en"},{"creatorName":"楫取, 和明","creatorNameLang":"ja"},{"creatorName":"カジトリ, カズアキ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kajitori","familyNameLang":"en"},{"familyName":"楫取","familyNameLang":"ja"},{"familyName":"カジトリ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kazuaki","givenNameLang":"en"},{"givenName":"和明","givenNameLang":"ja"},{"givenName":"カズアキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1971","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60399631","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60399631"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-11"}],"filename":"fishu_k_64_227.pdf","filesize":[{"value":"898.8 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2012076/files/fishu_k_64_227.pdf"},"version_id":"a4971d73-3132-4c8a-8b20-d4faa43108ba"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Industry; Tables; Analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"非負値行列因子分解による産業クラスター検出の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非負値行列因子分解による産業クラスター検出の試み","subitem_title_language":"ja"},{"subitem_title":"An Attempt to Detect Industry Clusters by Using Non-negative Matrix Factorizations","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1724312739034"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-11"},"publish_date":"2024-10-11","publish_status":"0","recid":"2012076","relation_version_is_last":true,"title":["非負値行列因子分解による産業クラスター検出の試み"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-25T05:53:28.150005+00:00"}
