We describe a method for extracting date/time expressions for SFBMT. SFBMT uses noun determination rules to extract nouns and a bilingual dictionary to obtain correspondence of the extracted nouns between the source and the target languages. In this method, we add a rule to extract date/time expressions and then extract date/time expressions from a Japanese-English bilingual corpus. The evaluation results shows that the precision of this method for Japanese sentences is 96.7％, with a recall of 98.2％ and the precision for English sentences is 94.7％, with a recall of 92.7％.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"168","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告自然言語処理（NL）"}],"bibliographicPageStart":"163","bibliographicIssueDates":{"bibliographicIssueDate":"2007-07-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"76(2007-NL-180)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":47822,"updated":"2025-01-22T08:49:28.492950+00:00","links":{},"created":"2025-01-18T23:13:12.606451+00:00"}
