[Objective] This study quantitatively analyzes the distribution and structural patterns of religion-related content in Korean history video lectures for foreign learners. Although religion and ideology are embedded across the curriculum as contextual elements rather than independent instructional objectives, empirical research quantifying their actual exposure remains scarce.
[Contents] Using lecture texts from the K-MOOC K-Academic Dissemination Project, this study built a keyword dictionary covering seven religious types. Text mining (TF, TF-IDF) and social network analysis (SNA) were employed to examine vocabulary distribution, chronological exposure, and semantic networks.
[Conclusions] The findings reveal three key points. First, each religious type formed a distinctive lexical network centered on its functional role in Korean society rather than its doctrinal system. Second, dominant religious discourse shifted dynamically over time—from prehistoric folk beliefs to Buddhist/Confucian dominance, modern national religions, and contemporary pluralization. Third, religious keywords consistently functioned as structural bridges connecting political, social, and cultural concepts. Thus, religion in these lectures is represented as a sociocultural mediator rather than an independent belief system.
