Abstract

This study presents the named entity annotation process conducted on Chosun Ilbo and Donga Ilbo articles from the 1920s–1930s by the Institute for the Study of Korean Modernity at Yonsei University, highlighting key methodological considerations. It examines the selection of Korean studies texts from the full corpus of published articles, the identification and classification of named entities, and the outcomes of this process. Additionally, the study reviews challenges encountered during annotation—including annotation tool selection, normalization of Chinese characters and variant spellings, annotation methods, and data interpretation—and details efforts to address these issues. As the first large-scale named entity annotation project on early 20th-century Korean newspaper articles, this study provides valuable insights for future researchers working with historical Korean texts.
