In this paper, we first describe the service specification corresponding to the first step, technical background, and evaluation of the current extraction accuracy, then finally introduce some use cases of the service. Although this service adopts a novel combination of a restrictive method using ontology-based rules and an example-based machine learning method using conditional random field, based on probability distribution, the main cotribution of the service is in practical aspect, that is, mash-up of several natural language processing techniques as a text triplification service, and deployment as a Web API freely available for public use so that non-expert easily use it.","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.LOD-21","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.LOD-21","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 2016"}]},"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"},{"creatorName":"Kawamura, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大須賀, 昭彦","creatorNameLang":"ja"},{"creatorName":"オオスガ, アキヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohsuga, Akihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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","filename":"advpub_LOD-21.pdf","filesize":[{"value":"357.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"advpub_LOD-21","url":"https://uec.repo.nii.ac.jp/record/9100/files/advpub_LOD-21.pdf"},"version_id":"7df7fc0f-5747-49e6-bf95-0fecd3310e4b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"information extraction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"triplification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linked open data","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LOD","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":"TEXT2LOD ～ テキスト情報のLOD化に向けたWeb APIの開発 ～","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TEXT2LOD ～ テキスト情報のLOD化に向けたWeb APIの開発 ～","subitem_title_language":"ja"},{"subitem_title":"TEXT2LOD -- Development of Web API for Triplification of Text Information --","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-04-09"},"publish_date":"2019-04-09","publish_status":"0","recid":"9100","relation_version_is_last":true,"title":["TEXT2LOD ～ テキスト情報のLOD化に向けたWeb APIの開発 ～"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-03-04T06:54:33.830658+00:00"}
