  Commonsense Reasoning

Recent advancements in reasoning-reinforced Large Language Models (LLMs) have
shown remarkable capabilities in complex reasoning tasks. However, the
mechanism underlying their utilization of different human reasoning skills
remains poorly investigated, especially for multilingual commonsense reasoning
that involves everyday knowledge across different languages and cultures. To
address this gap, we propose a Multilingual and Scalable Benchmark for
Skill-based Commonsense Reasoning (mSCoRe).
Our benchmark incorporates three key components that are designed to
systematically evaluate LLM's reasoning capabilities, including: (1) a novel
taxonomy of reasoning skills that enables fine-grained analysis of models'
reasoning processes, (2) a robust data synthesis pipeline tailored specifically
for commonsense reasoning evaluation, and (3) a complexity scaling framework
allowing task difficulty to scale dynamically alongside future improvements in
LLM abilities. Extensive experiments on eights state-of-the-art LLMs of varying
sizes and training approaches demonstrate that mSCoRe remains
significantly challenging for current models, particularly at higher complexity
levels. Our results reveal the limitations of such reasoning-reinforced models
when confronted with nuanced multilingual general and cultural commonsense. We
further provide detailed analysis on the models' reasoning processes,
suggesting future directions for improving multilingual commonsense reasoning
capabilities.
