ViLegalExpert: A Large-Scale Benchmark for Vietnamese Legal Retrieval and Question Answering from Real-World Consultations
ViLegalExpert benchmarks Vietnamese legal retrieval and QA on 172K real consultation questions.
ViLegalExpert is a Vietnamese legal benchmark built from authentic citizen-lawyer consultations, with more than 172,000 questions across 34 domains, professional answers, and expert-verified legal evidence. It supports information retrieval, extractive question answering, and abstractive question answering. Experiments find pretrained models strong on QA and hybrid retrieval best for retrieval, while mapping naturally worded questions to authoritative provisions remains difficult.
