Impact of Simultaneous Multilingual Fine-Tuning on XLM-R Precision in Low-Resource Euphemism Detection

Euphemisms are culturally variable and often ambiguous, posing challenges for language models, especially in low-resource settings. This paper investigates how cross-lingual transfer via sequential fine-tuning affects euphemism detection across five languages: English, Spanish, Chinese, Turkish, and Yoruba. We compare sequential fine-tuning with monolingual and simultaneous fine-tuning using XLM-R and mBERT, analyzing how performance is shaped by language pairings, typological features, and pretraining coverage. Results show that sequential fine-tuning with a high-resource L1 improves L2 perfo Research goal: How does increasing the number of languages in simultaneous fine-tuning affect the average precision of XLM-R on low-resource euphemism detection compared to sequential fine-tuning?
