VNFinsQA: Vietnamese Financial Question Answering Benchmark

Dataset Description

VNFinsQA is a benchmark dataset for evaluating Vietnamese financial question-answering systems. It contains 790 expert-annotated Vietnamese questions with ground-truth answers, collected from production financial QA systems and curated by securities analysts.

The dataset covers diverse financial question types including factual lookups, stock analysis, technical analysis, valuation, cross-stock comparisons, screening, investment recommendations, and macroeconomic questions. All questions are in Vietnamese and target the Vietnamese stock market (HOSE, HNX).

Supported Tasks

• Financial Question Answering: Given a Vietnamese financial question, generate an accurate answer grounded in financial data.
• Information Retrieval Evaluation: Evaluate retrieval systems on their ability to find relevant financial documents for answering questions.
• RAG System Benchmarking: Benchmark Retrieval-Augmented Generation systems on domain-specific Vietnamese financial queries.

Dataset Construction

1. Merged questions from 3 sources (production system logs and analyst contributions)
2. Filtered to Vietnamese single-turn questions only
3. Deduplicated by normalized text
4. Auto-assigned difficulty and multi-document requirement heuristics
5. Ground-truth answers provided by certified financial analysts (CFA or equivalent)
6. Filtered to questions with verified ground-truth answers only

Example

{
  "vnfinsqa_id": "VNFQ-0001",
  "question": "Phân tích doanh thu, biên lợi nhuận năm trước của cổ phiếu HPG",
  "tickers": "HPG",
  "question_category": "factual",
  "difficulty": "easy",
  "requires_multi_doc": false,
  "required_data_sources": "financial_report",
  "ground_truth": "HPG năm 2024: Doanh thu thuần đạt 138.855 nghìn tỷ VND (tăng 16,7% so với 2023). Lợi nhuận gộp 18.498 nghìn tỷ VND, biên lợi nhuận gộp ~13,3%. LNST đạt 12.020 nghìn tỷ VND (tăng 76,7% YoY), biên lợi nhuận ròng ~8,7%.",

}

Limitations

• Single institution: Questions collected from one Vietnamese securities firm
• Vietnamese only: All questions and answers are in Vietnamese
• Broad "other" category: 191/790 questions are categorized as "other"
• Temporal scope: Questions primarily reference 2020-2024 financial data
• Ground truth coverage: Answers reflect analyst knowledge at time of annotation; financial data may have since been updated
