The task was a shared task at the Second Workshop on Figurative Language Processing (ACL 2020), where each reply comes with the earlier turns of its conversation. The organizers supplied balanced, automatically labelled data: 5,000 tweets and 4,400… 2. **[Bilingual BSARD: Extending Statutory Article Retrieval to Dutch](https://md.research.elamur.ai/free/en/papers/lotfi-2025-bilingual-bsard-extending-statutory-article/)** *(2025 · 5 citations)* The paper addresses the lack of a Dutch benchmark for statutory article retrieval in multilingual jurisdictions such as Belgium. 3. **[MTEB-NL and E5-NL: Embedding Benchmark and Models for Dutch](https://md.research.elamur.ai/free/en/papers/banar-2026-mteb-nl-e5-nl-embedding/)** *(2026 · 4 citations)* Dutch has only a small share of the data inside multilingual embedding resources, and it had no broad benchmark or strong dedicated embedding models. 4. **[BEIR-NL: Zero-shot Information Retrieval Benchmark for the Dutch Language](https://md.research.elamur.ai/free/en/papers/lotfi-2025-beir-nl-zero-shot-information/)** *(2025 · 3 citations)* BEIR is the standard benchmark for zero-shot retrieval, but it contains only English, which leaves languages like Dutch with no comparable test suite. 5. **[bLLeQA: Benchmarking LLMs for Grounded Legal Question-Answering in French and Dutch](https://md.research.elamur.ai/free/en/papers/banar-2026-blleqa-benchmarking-llms-grounded-legal/)** *(2026)* Legal question-answering tools could make the law easier to reach for ordinary people. However, evaluation data for retrieval-augmented generation (RAG) in civil-law settings and smaller languages such as Dutch is rare. The authors extend the French LLeQA dataset into bLLeQA, a parallel French–Dutch benchmark built… ## All works 6 works of theirs in our library, the most cited first; 5 with a page here, the others link their original until we summarise them. 1. **[Sarcasm Detection Using an Ensemble Approach](https://md.research.elamur.ai/free/en/papers/lemmens-2020-sarcasm-detection-ensemble-approach/) [Workshop on Figurative Language Processing](https://md.research.elamur.ai/free/en/venues/figlang/)**Jens Lemmens, Ben Burtenshaw, Ehsan Lotfi, et al.*2020 · 56 citations* 2.
