Abstract
Previous studies have demonstrated the effectiveness of reasoning methods in eliciting multi-step reasoned answers from Large Language Models (LLMs) by leveraging in-context demonstrations. These methods, exemplified by Chain-of-Thought (CoT) and Program-Aided Language Models (PAL), have been shown to reason well in monolingual contexts, primarily in English. There has, however, been limited exploration of their abilities in other languages, especially in Italian.To gain a deeper understanding of the role of reasoning methods in in-context demonstrations, we propose a multidimensional analysis tailored to Italian, focusing on arithmetic and symbolic reasoning tasks. Our findings indicate that the effectiveness of reasoning methods varies significantly beyond English. Specifically, CoT, which relies on natural language demonstrations, is limited to English. Conversely, the structured nature of PAL in-context demonstrations facilitates multilingual comprehension, enabling LLMs to generate programmatic answers in Italian as well. Finally, for a more comprehensive overview, we observe that additional alignment methods do not improve downstream performances; in contrast, in some cases, they limit the abilities of the original models. This leads to significant improvements in the accuracy and quality of the generated responses.
