For promoting a greater number of consumer services on the web, a search function that can reveal what kinds of data are available would be helpful. However, if we assume that the open data is described in a triple language like Resource Description Framework (RDF) in future, full-text search is not suitable for data fragments, and a formal query language is difficult for ordinary users. Therefore, we propose a question answering service based on Linked Open Data. As the problems of using the open data as a knowledge source, we then focus on mapping of question sentence to data schema, and data acquisition. And we propose improvement of accuracy based on user feedback and acquisition of new data by user context information. We also present `Flower Voice\u0027 which is an application of the service for assisting with fieldwork and confirm the effectiveness.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "人工知能学会"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1527/tjsai.29.375", "subitem_relation_type_select": "DOI"}}]}, "item_10001_relation_17": {"attribute_name": "関連サイト", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1527/tjsai.29.375", "subitem_relation_type_select": "DOI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright © 人工知能学会 2014"}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1346-0714", "subitem_source_identifier_type": "ISSN"}]}, "item_10001_version_type_20": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "川村, 隆浩", "creatorNameLang": "ja"}, {"creatorName": "カワムラ, タカヒロ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "24667", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "大須賀, 昭彦", "creatorNameLang": "ja"}, {"creatorName": "オオスガ, アキヒコ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "24290", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawamura, Takahiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "24816", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohsuga, Akihiko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "24817", "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": "2019-04-09"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "29_29_375.pdf", "filesize": [{"value": "1.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1100000.0, "url": {"label": "29_29_375", "url": "https://uec.repo.nii.ac.jp/record/9104/files/29_29_375.pdf"}, "version_id": "268fc518-0c89-447a-9fa7-85d907cb9ce7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "linked open data", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "question answering system", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fieldwork", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "LODを対象としたユーザ参加型質問応答サービスの開発 ～ユーザフィードバックによる精度向上とコンテキスト自動登録手法の評価～", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "LODを対象としたユーザ参加型質問応答サービスの開発 ～ユーザフィードバックによる精度向上とコンテキスト自動登録手法の評価～", "subitem_title_language": "ja"}, {"subitem_title": "User Participatory Approach to Question Answering Service for LOD -- Accuracy Improvement by User Feedback and Automatic Context Registration --", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "13", "path": ["6"], "permalink_uri": "https://uec.repo.nii.ac.jp/records/9104", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2019-04-09"}, "publish_date": "2019-04-09", "publish_status": "0", "recid": "9104", "relation": {}, "relation_version_is_last": true, "title": ["LODを対象としたユーザ参加型質問応答サービスの開発 ～ユーザフィードバックによる精度向上とコンテキスト自動登録手法の評価～"], "weko_shared_id": -1}
