Among anaphoric expressions, though cataphoric expressions are not processed so much before, it is necessary to process them in order to establish the high quality system of natural language processing. In this research, we extracted cataphoric expressions using surface expressions in Japanese sentences. We first extracted sentences which may contain cataphoric expressions by using general clues. Then we constructed a set of rules for extracting cataphoric expressions by checking those sentences. In recognition of cataphoric expressions in held-out texts, we obtained the correct recognition scores of 47.7% and the recall scores of 94.2%. Also we obtained the correct recognition scores of 71.2%, in retrieving antecedent of the recognized cataphoric expressions.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"42","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告自然言語処理（NL）"}],"bibliographicPageStart":"37","bibliographicIssueDates":{"bibliographicIssueDate":"1995-07-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"69(1995-NL-108)","bibliographicVolumeNumber":"1995"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:14:14.828337+00:00","id":49171,"links":{}}
