Abstract: This study aims to extract topics from news articles on DMZ tourism published between 1990 and 2020. This study uses LDA to extract topics within the contents of news articles on DMZ tourism. Furthermore, this study aims to examine the trends of each topic within news articles and identify the characteristics of topics over the past 30 years by developing graphs. A total of 23,093 news articles published from 1990 to 2020 were collected. The data were analyzed using LDA, descriptive analysis, odd ratios, and visualized graphs. The results found that news articles on DMZ tourism can provide considerable information in terms of political, social, and environmental issues. The results provide profiles of news articles on DMZ tourism and identify the unique topics and characteristics of these news articles. The study presents findings regarding topic trends over the last 30 years. All topics show an upward trend from 1990 to 2020. Significant issues have attracted attention to the DMZ region. Furthermore, the findings demonstrate spatial and temporal differences in the volumes of topics. This study identified topics from the past 30 years and important issues related to DMZ tourism that can strengthen the unique features of the DMZ and surrounding area, promoting tourism products and content. The present study contributes to identifying topics of DMZ tourism and temporal changes from 1990 to 2020. The findings can provide meaningful insight into developing policies for DMZ tourism.
