In order to spread out semantic web, it is necessary to attach meta-data to web contents. However it is difficult to attach meta-data from existing web contents by hand. We have analyzed web contents in order to construct ontology and developed the tool to support attachment of meta-data. We can utilize the information extraction technology for attachment of meta-data. Namely, our tool assigns extracted named entities such as person name, place, date and so on, to attributes such as lecturers, meeting places and so on . The relations of attributes are represented as the RDF schema. As the evaluation results, we get a recall score of 0.63 and a precision score of 0.56.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"54","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告自然言語処理（NL）"}],"bibliographicPageStart":"49","bibliographicIssueDates":{"bibliographicIssueDate":"2003-09-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"98(2003-NL-157)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":48258,"updated":"2025-01-22T08:35:25.591959+00:00","links":{},"created":"2025-01-18T23:13:32.969215+00:00"}
