Abstract
LLMs have been showing limitations when it comes to cultural coverage and competence, and in some cases show regional biases such as amplifying Western and Anglocentric viewpoints. While there have been works analysing the cultural capabilities of LLMs, there has not been specific work on highlighting LLM regional preferences when it comes to cultural-related questions. In this work, we propose a new dataset based on a comprehensive taxonomy of Culture-Related Open Questions (CROQ). The results show that, contrary to previous cultural bias work, LLMs show a clear tendency towards countries such as Japan. Moveover, our results show that when prompting in languages such as English or other high-resource ones, LLMs tend to provide more diverse outputs and show less inclinations towards answering questions highlighting countries for which the input language is an official language. Finally, we also investigate at which point of LLM training this cultural bias emerges, with our results suggesting that the first clear signs appear after supervised fine-tuning, and not during pre-training.

- LLMのアウトプットはなぜか日本文化に偏ってることが多々あるけどこれは構造的なバイアスだよね、という話です。 もう少し丁寧に言うと、LLMがグローバルに流通している文化(目立つ文化)に寄っていきがちという一般現象の中で、日本が強く出ているケースが観測された、という話です。 Why are all LLMs Obsessed with Japanese Culture? On the Hidden [bsky, 1 points, 1 comments]
