has recently been newly developed as an OCR for Early-Modern Japanese Printed Books, and it can perform layout analysis with sufficient accuracy for the single-column vertical layouts found in many general books. However, it cannot perform layout analysis with sufficient accuracy for modern books with multi-column layouts and multi-size headings, such as newspapers. Therefore, we attempted to perform text extraction for Early-Modern Japanese Printed Books with layouts that include multi-columns and multi-size headlines using CRAFT and the resolution pyramid. The ultimate goal of OCR construction for multi-column and multi-size headlines is to convert Japanese newspapers published locally by Japanese immigrants after the Meiji period into text. In this paper, we focus on the Imperial Diet Proceedings as an example of an Early-Modern Japanese Printed Book containing multi-column and multi-size headlines, which is not as difficult to convert into text as Japanese newspapers. The proposed method is validated by comparing the accuracy of the proposed method with that of layout analysis by other OCR methods for the Imperial Diet Proceedings.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"79","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌数理モデル化と応用（TOM）"}],"bibliographicPageStart":"67","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"16"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":228860,"updated":"2025-01-19T11:41:32.517508+00:00","links":{}}
