Framework Validates LLM Judge Ratings Under Indeterminacy

Researchers introduce a framework for validating LLM-as-judge systems under rating indeterminacy, focusing on response-set elicitation, aggregation, and agreement measurement. The framework formalizes how response-set distributions map to forced-choice ratings via O_i = F_i θ_i, highlights intra-rater disagreement preservation, and recommends probabilistic aggregation plus human–judge agreement metrics to avoid misleading evaluations.
Key Points
- 1Proposes response-set elicitation allowing raters to select multiple reasonable labels to capture intra-rater disagreement
- 2Shows forced-choice aggregation obscures rating indeterminacy, producing misleading judge performance estimates in subjective tasks
- 3Recommends probabilistic aggregation and human–judge agreement metrics to better validate LLM judges in deployment
Scoring Rationale
Introduces a practical formal framework and elicitation methods, with strong applicability but limited large-scale empirical validation.
