arXiv:2603.09403v2 Announce Type: replace Abstract: Validating evaluation metrics for NLG typically relies on expensive and time-consuming human annotations, which predominantly exist only for English datasets. We propose LLM as a Meta-Judge, a scalable framework that utilizes LLMs to generate synthetic evaluation datasets via controlled semantic degradation of real data, replacing human judgment. We validate our approach using \textit{meta-correlation}, measuring the alignment between metric rankings derived from synthetic data and those from standard human benchmarks. Experiments across Mach
The proliferation of complex NLP models necessitates more efficient and reliable evaluation methods, especially as human annotation becomes a bottleneck for non-English languages and specialized tasks.
This development offers a scalable and potentially language-agnostic approach to validating NLP evaluation metrics, which is crucial for accelerating AI development and ensuring its reliability across diverse applications.
The reliance on expensive human annotations for NLP metric validation can be significantly reduced or replaced by LLM-generated synthetic data, potentially democratizing access to robust evaluation methods.

Faster iteration and deployment of more accurate and robust NLP models due to streamlined evaluation.
Increased accessibility and performance of AI in smaller language markets or for highly specialized domains previously underserved by human annotation.
A potential shift in AI ethics and bias detection, as LLMs could introduce their own biases into the evaluation dataset generation process, requiring new validation methods for the meta-judge itself.
