q2 i? Gemini 2.0 Flash passed three reliability evaluations as an automatic annotator of feedback focus types: Cohen's Kappa of 0.78 with human annotators, the Alt-Test, and consistency of conclusions with human annotations. → Norah Almousa 2026

q2 · i? · design · r3

Validation study of LLM-based annotation of feedback focus types, using a 100-instance gold-standard set for inter-annotator agreement and Alt-Test, and a 400-instance test set for conclusion consistency. Gemini 2.0 Flash achieved "a Cohen's Kappa of 0.78 with human annotators" and passed all three evaluations.

"Gemini 2.0 Flash was selected as the annotator, passing all three evaluations: achieving a Cohen's Kappa of 0.78 with human annotators, passing the Alt-Test, and producing conclusions consistent with those drawn from human annotations."
