Moral Semantics Survive Machine Translation: Cross-Lingual Evidence from Moral Foundations Corpora
Researchers have demonstrated that machine translation, particularly using LLMs, can effectively preserve subtle moral cues across languages. A study using approximately 50,000 morally-annotated social media posts from Polish found that direct translation maintained enough moral semantics for cross-lingual machine learning. Despite some limitations with slang and culturally specific expressions, the translation accuracy was high, with a mean cosine similarity of 0.86, suggesting machine translation is a viable method for moral values research in under-resourced languages.
