2 つの手法として，サポートベクターマシンに基づく手法と，分類と根拠となる部分文字列の抽出を同時に行うニューラルネットワークによる手法を実装した．不動産に関する対話のコーパスを利用した評価実験の結果，サポートベクターマシンに基づく手法がより良好な結果を示すことがわかった．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"9","bibliographic_titles":[{"bibliographic_title":"研究報告自然言語処理（NL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-07-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2018-NL-236"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:56:20.287647+00:00","id":190365,"links":{}}
