AI 中文摘要
本研究分析了日本学术振兴会科学研究费补助金（KAKENHI）科学研究（C）类资助项目的摘要被归类为AI生成的程度。分析覆盖了2022财年至2026财年五年间资助的项目，被归类为AI生成的摘要数量从2025财年开始增长，2026财年约20%的摘要被归类为AI生成。尽管比例存在一定差异，但在多个评审类别中均观察到被归类为AI生成的摘要，这些发现表明生成式AI的使用已开始在科学研究（C）所代表的众多研究领域中普及。
英文摘要
This study analyzes the extent to which abstracts of projects funded under the Scientific Research (C) category of the Grants-in-Aid for Scientific Research (KAKENHI) were classified as AI-generated. The analysis covers projects funded over the five-year period from FY2022 to FY2026. The number of abstracts classified as AI-generated began to increase in FY2025, and approximately 20% of the abstracts were classified as AI-generated in FY2026. Although the proportions varied to some extent, abstracts classified as AI-generated were observed in many review categories. These findings indicate that the use of generative AI has begun to spread across many research fields represented in Scientific Research (C).
