On the other hand, it becomes difficult for him/her to choose desirable or valuable ones. Then various recommendation systems have been studied and put into practical use to support users' selection. Though \"accuracy\" has been used as the evaluation of these systems so far, it is said that other evaluation factors are also needed from the aspect of the satisfaction of users. \"Serendipity,\" which includes novelty or unexpectedness, is one of the evaluation indexes for user satisfaction. This paper defines and quantifies \"Personalizability\" as a part of \"Serendipity.\" This paper proposes a recommendation system considering \"Personalizability,\" and applies the proposed method to benchmark data. It shows that this method can adjust the balance between \"Accuracy\" and \"Personalizability\" and it is superior to the conventional method in terms of \"Personalizability.\"","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"http://id.nii.ac.jp/1001/00091259/"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/20852"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人情報処理学会","subitem_publisher_language":"ja"}]},"item_10_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://id.nii.ac.jp/1001/00091259/","subitem_relation_type_select":"URI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
