This paper introduces a new benchmark, KCL, specifically designed to evaluate the legal reasoning abilities of LLMs in Korean. The key contribution is the focus on knowledge-independent evaluation, achieved through question-level supporting precedents. This allows for a more accurate assessment of reasoning skills separate from pre-existing knowledge. The benchmark's two components, KCL-MCQA and KCL-Essay, offer both multiple-choice and open-ended question formats, providing a comprehensive evaluation. The release of the dataset and evaluation code is a valuable contribution to the research community.
Key Takeaways
- •Introduces the Korean Canonical Legal Benchmark (KCL) for evaluating LLMs' legal reasoning.
- •Focuses on knowledge-independent evaluation using question-level supporting precedents.
- •Includes both multiple-choice (KCL-MCQA) and open-ended (KCL-Essay) question formats.
- •Demonstrates performance gaps in existing models, particularly in open-ended tasks.
- •Highlights the superior performance of reasoning-specialized models.
