Cross-linguality Human Annotated Data LLM evaluation Paraphrasing

Linguist and lexicographer by training, currently pursuing a PhD in AI. My research focuses on the paraphrasing capabilities of LLMs in cross-lingual contexts, with an emphasis on enhancing this capability in downstream applications. I prioritize the use of human-annotated datasets and lexicographic resources to provide models with high-quality training data, aiming for more accurate and reliable results.
