Benchmarking LLM-as-a-Judge for Long-Form Output Evaluation
The paper introduces LongJudgeBench, a benchmark designed to evaluate large language models (LLMs) as judges for long-form outputs. It highlights the challenges of reliably assessing long-form content compared to short-form evaluations. The study reveals significant reliability gaps in current LLM judges and emphasizes the need for more robust evaluation methods.
- ▪LongJudgeBench is a comprehensive benchmark for evaluating LLM judges on long-form outputs.
- ▪Current LLM judges show instability across different scenarios, indicating a reliability gap.
- ▪The evaluation of long-form outputs requires complex assessments beyond just output length.
