🤖 AI Summary
The widespread adoption of generative AI in academic research has intensified ethical governance challenges—including authorship attribution, data bias, transparency, and privacy—while university policies lag behind technological practice. Method: This study constructs the first nationwide database of AI research guidelines from 127 U.S. universities and proposes a three-dimensional analytical framework (“applicable scenarios–responsible actors–risk levels”). It integrates computational content analysis, LDA topic modeling, and expert-validated coding to identify governance paradigms. Contribution/Results: Two dominant paradigms emerge: “tool neutrality” and “process embedding.” Critically, only 38% of guidelines explicitly define authorship norms for AI-assisted writing and data analysis, exposing significant policy gaps and implementation ambiguity. The study delivers a reproducible methodological toolkit and empirically grounded benchmarks to advance ethical AI governance in higher education.
