Check-Eval: A Checklist-based Approach for Evaluating Text Quality
This addresses the problem of unreliable text evaluation for natural language generation tasks, offering a more interpretable method, though it appears incremental as it builds on prior LLM-based evaluation approaches.
The paper tackles the challenge of evaluating text quality from large language models by proposing Check-Eval, a checklist-based framework that achieves higher correlations with human judgments than existing metrics like G-Eval and GPTScore on benchmark datasets.
Evaluating the quality of text generated by large language models (LLMs) remains a significant challenge. Traditional metrics often fail to align well with human judgments, particularly in tasks requiring creativity and nuance. In this paper, we propose \textsc{Check-Eval}, a novel evaluation framework leveraging LLMs to assess the quality of generated text through a checklist-based approach. \textsc{Check-Eval} can be employed as both a reference-free and reference-dependent evaluation method, providing a structured and interpretable assessment of text quality. The framework consists of two main stages: checklist generation and checklist evaluation. We validate \textsc{Check-Eval} on two benchmark datasets: Portuguese Legal Semantic Textual Similarity and \textsc{SummEval}. Our results demonstrate that \textsc{Check-Eval} achieves higher correlations with human judgments compared to existing metrics, such as \textsc{G-Eval} and \textsc{GPTScore}, underscoring its potential as a more reliable and effective evaluation framework for natural language generation tasks.
