This paper addresses the development of a Jeju-specific personalized travel recommendation service that caters to both information-disadvantaged groups, such as seniors, and the growing number of international tourists. To build this service, accommodation data was collected from multiple sources, including the Jeju Tourism Association, public data portals, and AI Hub. Recognizing the importance of digital transformation in tourism, particularly for inclusivity, the dataset was extensively cleaned and integrated to provide comprehensive information on hotels, amenities, surrounding facilities, and user reviews. This unified dataset supports the creation of an AI-powered recommendation system designed to bridge accessibility gaps and overcome language and cultural barriers. By providing tailored travel experiences, this study is expected to enhance Jeju’s competitiveness and promote a more inclusive and welcoming tourism environment.
