1. Sarcasm Detection Using an Ensemble Approach (2020 · 56 citations)
   This paper addresses sarcasm classification of social-media replies. 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 (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 (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 (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 (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…
