Multimodal Pretraining and Sequential Fine-Tuning for Zero-Shot Cross-Lingual 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 the combination of multimodal pretraining (e.g., CLIP) with sequential fine-tuning on XLM-R impact zero-shot cross-lingual euphemism detection performance on XTREME-R, compared to text-only pretraining, as measured by macro-F1 and cross-entropy loss?
