Assuming that a patent based on a variety of technological bases tends to be an important patent that is cited more often, this study examines the influence of the number of cited patents’ classifications and compares it with other factors, such as the numbers of inventors, classifications, pages, and claims. Multiple linear, logistic, and zero-inflated negative binomial regression analyses using these factors are performed. Significant positive correlations between the number of classifications of cited patents and the citation frequency are observed for all the models. Moreover, the multiple regression analyses demonstrate that the number of classifications of cited patents contributes more to the regression than do other factors. This implies that, if confounding between factors is taken into account, it is the diversity of classifications assigned to backward citations that more largely influences the number of forward citations.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Netherlands"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s11192-013-0953-4","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© Akade´miai Kiado´, Budapest, Hungary 2013"},{"subitem_rights":"The final publication is available at Springer via http://dx.doi.org/10.1007/s11192-013-0953-4"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0138-9130","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00441963","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yoshikane, Fuyuki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-06-11"}],"displaytype":"detail","filename":"Sm_96-1.pdf","filesize":[{"value":"387.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Sm_96-1","url":"https://tsukuba.repo.nii.ac.jp/record/33887/files/Sm_96-1.pdf"},"version_id":"2265d946-c6ca-4da3-9351-cac63079c8a2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Multiple regression analysis of a patent’s citation frequency and quantitative characteristics: the case of Japanese patents","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Multiple regression analysis of a patent’s citation frequency and quantitative characteristics: the case of Japanese patents"}]},"item_type_id":"5","owner":"1","path":["1003","3082"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-06-11"},"publish_date":"2015-06-11","publish_status":"0","recid":"33887","relation_version_is_last":true,"title":["Multiple regression analysis of a patent’s citation frequency and quantitative characteristics: the case of Japanese patents"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:02:34.340078+00:00"}
