indexed in SSCI and KCI between 2023 and 2025, following the release of ChatGPT.Among 63 SSCI articles, practical applications dominated, with research methods (22.2%), education (20.6%), and political communication (15.9%) as the top categories.In contrast, there were only nine KCI articles, which took more exploratory approaches to the topic.The study further conducts LLM usage detection based on article abstracts, revealing widespread adoption of LLMs in Korean political science.Using keyword-based detection and linguistic feature analysis, it shows that the usage rate of ChatGPT-related keywords in English abstracts rose by approximately 85% from 2022 to 2023, while linguistic markers such as comma usage in Korean abstracts showed a sharp shift after ChatGPT's release.Finally, the paper reviews key ethical challenges raised by LLM usage and calls for greater transparency and clearer guidelines.This research offers a comprehensive mapping of LLM-related studies in political science and provides quantitative insights into LLM usage in Korean political science through a dual-method detection approach.2022 11 GPT , (LLM) . .
