About

Content & Construction: ViLegalExpert is constructed from real-world online consultations between citizens and lawyers in Vietnam. It includes a corpus of authoritative government documents (Constitution, laws, decrees) linked via expert annotation to the consultation questions.

Scoring & Findings: The benchmark supports legal information retrieval, extractive QA, and abstractive QA. Experiments reveal substantial challenges in mapping natural language queries to specific provisions; hybrid retrieval performs best for evidence finding.
