In this paper, we propose an associative retrieval model for the flexibility on a relational database system. The model is of a retrieval type that retrieves from one key tuple to other tuples in a database. We show two types of retrieval models : one is the direct association and another the successive association. By using the \"entropy\" concept, the characteristics of the data is quantified. Then the degree of association is also quantified. The model is discussed from the view point of the mathematical properties of the degree of association.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00033244","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Okayama University of Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Management Engineering, Osaka Electro-Communication University"},{"subitem_text_language":"en","subitem_text_value":"Department of Electronic Engineering, Okayama University of Science"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学"},{"subitem_text_language":"ja","subitem_text_value":"大阪電気通信大学経営工学科"},{"subitem_text_language":"ja","subitem_text_value":"岡山理科大学電子工学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1990-03-20"}],"displaytype":"detail","filename":"KJ00000063410.pdf","filesize":[{"value":"550.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://ous.repo.nii.ac.jp/record/857/files/KJ00000063410.pdf"},"version_id":"1dc0c89d-6ddc-4150-9f74-4fd825be36ce"}]},"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":"リレーショナルデータベースシステムにおける連想検索機能","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リレーショナルデータベースシステムにおける連想検索機能","subitem_title_language":"ja"},{"subitem_title":"Associative Retrieval Modelling for Relational Database Systems","subitem_title_language":"en"},{"subitem_title":"リレーショナル データベース システム ニオケル レンソウ ケンサク キノウ","subitem_title_language":"ja-Kana"}]},"item_type_id":"1","owner":"14","path":["323"],"pubdate":{"attribute_name":"PubDate","attribute_value":"1990-03-20"},"publish_date":"1990-03-20","publish_status":"0","recid":"857","relation_version_is_last":true,"title":["リレーショナルデータベースシステムにおける連想検索機能"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-09-27T05:56:45.187551+00:00"}
