KLEAR: Knowledge-Matched LLM Evaluation in Korean across Application Requirements via Controlled Benchmark Transformation

Read the original on arXiv Computation and Language →

KLEAR is a framework that creates knowledge‑matched contrasts for Korean LLM evaluation by varying application demand while keeping the required knowledge constant. It identifies the knowledge behind each source question, generates more complex application questions, and refines them through automated and human validation. Experiments show that these controlled sets reveal persistent failures in LLMs when application demand increases, even with the necessary knowledge supplied.

KBS: A Korean Benchmark Suite for Foundation Model Evaluation

The paper introduces KBS, a Korean Benchmark Suite that includes six datasets—Ko-ARC, Ko-GSM8K, Ko-EQ-Bench, Ko-WinoGrande, Ko-LAMBADA, and Ko-IFEval—covering nine capabilities across 9,396 items. It emphasizes a non‑translation approach by reviewing, localizing, and redesigning tasks for Korean, and evaluates Korean‑developed, multilingual open, and closed API models under protocols that consider model access, prompt format, and scoring differences. The results highlight that Korean benchmark scores are influenced by task construction, scoring rules, prompting, and post‑training, suggesting that evaluations should report both final scores and the settings used.
