PDF テキストと，それらに該当する点字のデータから，対応する文のペアをパターンマッチングで選び出す．次に，この文対に対して，既存の振り仮名注釈付きコーパスや形態素解析辞書などから事前に収集した漢字に対する振り仮名候補に基づく文字レベルのマッチングを行い，振り仮名注釈付き日本語コーパスを構築する．約 4.1 億文字の漢字仮名交じり文の中から，約 3.5 億文字の文に含まれるすべての漢字に対して振り仮名の自動注釈を行った．これにより同形異音語を含む文を選び出せることを確認した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告アクセシビリティ（AAC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-02-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2021-AAC-15"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:11:11.059270+00:00","id":209902,"links":{}}
