In this policy recommendation, we propose a risk chain model (RCModel) that supports AI service providers in proper risk assessment and control. We hope that RCModel will contribute to the realization of trustworthy AI services.\n\nOverview of RCModel\n 1)Organization and structure of risk components\nThere are a number of potential risk factors involved in provision of AI services. In RCModel, these factors are segregated into (1) technical components of the AI system, (2) components related to the code of conduct (including communication with users) of the service provider, and (3) components related to the user’s understanding, behavior, and usage environment.\n\n2)Identification of risk scenarios and risk-contributing factors\nRCModel helps identify risk scenarios related to AI services, such as unfair decisions and uncontrollable accidents. It then identifies risk factors for priority risk scenarios.\n\n3)Visualization of risk chains and planning risk control\nBecause it is difficult to reduce risk sufficiently on a factor basis, AI service providers can consider stepwise risk reduction by visualizing the relationships (risk chain) among the risk factors related to risk scenarios. This allows consideration of where a risk exists and its effective and efficient control.\n\nPolicy Recommendations for Future Development and Implementation of AI Services Using RCModel\nPolicy Recommendation 1: Enhance understanding of risk scenarios and factors\nService providers need to properly understand the risk factors associated with their AI services. They should also pay attention to social incidents involving the use of AI technologies and recognize important risk scenarios.\n\nPolicy Recommendation 2：Promotion of appropriate risk controls using RCModel\nAI service providers should formulate their risk control measures by analyzing RCModel’s risk chain. It is neither necessary nor always possible to reduce all the risks identified; therefore, appropriate controls should be established within an enterprise based on factors such as magnitude of risks posed, technical difficulty, cost-effectiveness, and continuity.\n\nPolicy Recommendation 3：Promoting and updating dialogue among stakeholders\nRCModel should be used to facilitate dialogue among AI service providers, AI developers, and users. In addition, a system should be established to clarify risk tolerance, create risk scenarios, structure risk factors, examine risk control models, and create a common understanding on the scope of each stakeholder’s responsibility.","subitem_description_type":"Abstract"}]},"item_8_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"160903","nameIdentifierScheme":"WEKO"}],"names":[{"name":"東京大学未来ビジョン研究センター技術ガバナンス研究ユニット"}]}]},"item_8_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute for Future Initiatives, The University of Tokyo"}]},"item_8_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://ifi.u-tokyo.ac.jp/en/news/4815/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ifi.u-tokyo.ac.jp/en/news/4815/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://confit.atlas.jp/guide/event/jsai2020/subject/4N2-OS-26a-02/tables?cryptoId="}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://confit.atlas.jp/guide/event/jsai2020/subject/4N2-OS-26a-02/tables?cryptoId=","subitem_relation_type_select":"URI"}}]},"item_8_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"CC BY 4.0"}]},"item_8_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Technology, Governance Policy Research Unit  Institute for Future Initiatives  The University of Tokyo"}],"nameIdentifiers":[{"nameIdentifier":"160902","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-06"}],"displaytype":"detail","filename":"policy_recommendation_tg_20200706.pdf","filesize":[{"value":"666.4 kB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"label":"policy_recommendation_tg_20200706.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54251/files/policy_recommendation_tg_20200706.pdf"},"version_id":"f76561ab-cff9-48cf-8c25-dfd33122e505"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"RCModel, a Risk Chain Model for Risk Reduction in AI Services","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RCModel, a Risk Chain Model for Risk Reduction in AI Services","subitem_title_language":"en"}]},"item_type_id":"8","owner":"1","path":["8322","8325"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-07-06"},"publish_date":"2020-07-06","publish_status":"0","recid":"54251","relation_version_is_last":true,"title":["RCModel, a Risk Chain Model for Risk Reduction in AI Services"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-17T07:31:21.294444+00:00"}
