CheckEval: Robust Evaluation Framework using Large Language Model via Checklist


Core Concepts
CheckEval introduces a novel evaluation framework using Large Language Models, focusing on detailed sub-aspects and Boolean questions to enhance interpretability, reliability, and consistency in evaluations.
Abstract
Introduction: Large Language Models (LLMs) have revolutionized AI capabilities. LLMs are increasingly used for evaluating text quality. Challenges in Evaluation: Ambiguity and inconsistency in evaluation criteria. Likert scale struggles with aspects like 'fluency' and 'coherence.' CheckEval Framework: Divides evaluation criteria into detailed sub-aspects. Constructs a checklist of Boolean questions for each aspect. Simplifies evaluation process and enhances reliability. Validation: Strong correlation with human judgments. High Inter-Annotator Agreement. Related Work: Previous studies on LLM-based evaluators and decomposition strategies. Design of CheckEval: Aspect Selection, Checklist Generation, and Checklist-based Evaluation stages. Case Study: Correlation analysis against baseline metrics. Robustness analysis using Fleiss' Kappa. Future Work: Extending task coverage and improving score aggregation. Conclusion: CheckEval offers detailed, interpretable, and reliable evaluations.
Stats
CheckEval indicates a strong correlation with human judgments. CheckEval demonstrates a highly consistent Inter-Annotator Agreement. CheckEval achieved the highest Kendall Tau correlation among consistency, fluency, and relevance.
Quotes
"CheckEval significantly clarifies the evaluation process and enhances consistency among different evaluators." "CheckEval offers detailed and interpretable evaluation results."

Deeper Inquiries

How can CheckEval be adapted to evaluate text quality in different languages or domains?

CheckEval can be adapted to evaluate text quality in different languages or domains by customizing the checklist based on the specific linguistic characteristics or domain-specific requirements. When evaluating text in different languages, the checklist questions can be translated and adjusted to account for language-specific nuances. For different domains, the key components and questions can be tailored to reflect the unique aspects of that domain. Additionally, incorporating domain-specific terminology and context into the checklist can enhance the evaluation's relevance and accuracy.

What are the potential limitations of relying solely on LLMs for evaluation, as demonstrated by CheckEval's performance?

One potential limitation of relying solely on LLMs for evaluation, as demonstrated by CheckEval's performance, is the model's inherent biases and limitations. LLMs may not always capture the full context or nuances of human language, leading to potential inaccuracies in evaluation. Additionally, LLMs may struggle with understanding sarcasm, humor, or cultural references, which can impact the quality of evaluations. Furthermore, LLMs may exhibit biases present in the training data, affecting the objectivity and fairness of evaluations.

How can the principles of CheckEval be applied to improve other types of evaluation frameworks beyond text quality assessments?

The principles of CheckEval can be applied to improve other types of evaluation frameworks beyond text quality assessments by focusing on detailed sub-aspects, constructing checklists of specific criteria, and utilizing a binary question format for evaluation. This approach can enhance the interpretability, reliability, and consistency of evaluations in various domains. By decomposing evaluation criteria into discrete components and utilizing clear, Boolean questions, other evaluation frameworks can benefit from increased precision, flexibility, and objectivity. Additionally, the customizable and interactive nature of CheckEval can be adapted to suit different evaluation needs, ensuring a robust and effective assessment process.
