Researchers have developed a new benchmark, LexNeo-Bench, to evaluate how well large language models understand lexical borrowing in low-resource languages like Luxembourgish. The benchmark, derived from a Luxembourgish news corpus, tests models on classifying borrowings and detecting neologisms. When provided with a linguistic knowledge graph as context, the models' accuracy in identifying borrowed words significantly improved, demonstrating the value of lexicon-aware prompting for evaluating LLMs in multilingual settings.
