Translating English instruction sets into it is a weak option, because machine translation into the language is poor and tends to produce unnatural or culturally off targets. 3. **[ltzGLUE: Luxembourgish General Language Understanding Evaluation](https://md.research.elamur.ai/free/en/papers/plum-2026-ltzglue-luxembourgish-general-language-understanding/)** *(2026)* Luxembourgish (LTZ) has roughly 400k speakers and few NLU resources. Most existing tasks come from news text and often contain under a thousand instances, so model comparisons for the language are unreliable. The authors address this with ltzGLUE, a GLUE-style benchmark of eight sentence- and token-level… 4. **[LëtzCross: A Cross-Lingual Page-Level Benchmark for Multimodal Retrieval over Luxembourgish Documents](https://md.research.elamur.ai/free/en/papers/bachyr-2026-l-etzcross-cross-lingual-page/)** *(2026)* Page-image retrievers in the ColPali family handle visually rich PDFs well, but it was unclear how they behave when queries and documents are in different languages and one of those languages is low-resource. 5. **[When English Isn't the Best Teacher: Source Language Effects in Cross-Lingual In-Context Learning](https://md.research.elamur.ai/free/en/papers/philippy-2026-when-english-isn-t-best/)** *(2026)* The paper asks whether the rules for choosing a source language in fine-tuning-based cross-lingual transfer also apply to few-shot In-Context Learning (ICL). 6. **[Why Low-Resource NLP Needs More Than Cross-Lingual Transfer: Lessons Learned from Luxembourgish](https://md.research.elamur.ai/free/en/papers/philippy-2026-why-low-resource-nlp-needs/)** *(2026)* This position-style paper asks whether cross-lingual transfer from high-resource languages can replace dedicated work on a low-resource language. ## All works 8 works of theirs in our library, the most cited first; 6 with a page here, the others link their original until we summarise them. 1. **[LuxEmbedder: A Cross-Lingual Approach to Enhanced Luxembourgish Sentence Embeddings](https://md.research.elamur.ai/free/en/papers/philippy-2025-luxembedder-cross-lingual-approach-enhanced/) [International Conference on Computational Linguistics (COLING)](https://md.research.elamur.ai/free/en/venues/coling/)**Fred Philippy, Siwen Guo, Jacques Klein, et al.*2025 · 8 citations* 2.
