New framework meta-evaluates text generation metrics, finds simple methods competitive with LLM judges

Researchers have developed a new regression-based framework for meta-evaluating text generation metrics, moving beyond traditional correlation estimates. This approach aims to provide a more stable and comparable measure of metric capability across different datasets and languages. The framework was tested on a large-scale, multi-lingual style-personalized text generation benchmark across 10 languages and four evaluation dimensions. The findings indicate that simple string- and embedding-based metrics can perform as well as sophisticated LLM judges when calibrated to human ratings, and the study identified factors influencing metric performance and conditions favoring metric ensembles.
