HVU_QA

HVU_QA is an open-source Vietnamese Question–Context–Answer (QCA) corpus and supporting tools for building FAQ-style question generation systems in low-resource languages. The dataset was created using a fully automated pipeline that combines web crawling from trustworthy sources, semantic tag-based extraction, and AI-assisted filtering to ensure high factual accuracy.

📋 Dataset Description

• Language: Vietnamese
• Format: SQuAD-style JSON
• Total samples: 30,000 QCA triples (full corpus released)
• Domains covered: Social services, labor law, administrative processes, and other public service topics.
• Structure of each sample:
  • Question: Generated or extracted question
  • Context: Supporting text passage from which the answer is derived
  • Answer: Answer span within the context

⚙️ Dataset Creation

Pipeline:

1. Selecting relevant QA websites from trusted sources.
2. Automated data crawling to collect raw QA webpages.
3. Extraction via semantic tags to obtain clean Question–Context–Answer triples.
4. AI-assisted filtering to remove noisy or factually inconsistent samples.

📊 Quality Evaluation

A fine-tuned VietAI/vit5-base model trained on HVU_QA achieved:

Metric	Score
BLEU	90.61
Semantic similarity	97.0% (cos ≥ 0.8)
Human grammar score	4.58 / 5
Human usefulness score	4.29 / 5

These results confirm that HVU_QA is a high-quality resource for developing robust FAQ-style question generation models.

⚡ How to Use

📦 Install Dependencies

pip install datasets transformers sentencepiece safetensors accelerate evaluate sacrebleu rouge-score nltk scikit-learn

(Install PyTorch separately from pytorch.org if not installed yet.)

📥 Load Dataset from Hugging Face Hub

from datasets import load_dataset

ds = load_dataset("DANGDOCAO/GeneratingQuestions", split="train")
print(ds[0])

🚀 Example Usage

🔹 Fine-tuning

python fine_tune_qg.py

This will:

1. Load the dataset from 30ktrain.json.
2. Fine-tune VietAI/vit5-base.
3. Save the trained model into t5-viet-qg-finetuned/.

(Or download the pre-trained model: t5-viet-qg-finetuned.)

🔹 Generating Questions

python generate_question.py

Example:

Input passage:
Iced milk coffee is a famous drink in Vietnam.
Number of questions: 5

Output:

1. What type of coffee is famous in Vietnam?
2. Why is iced milk coffee popular?
3. What ingredients are included in iced milk coffee?
4. Where does iced milk coffee originate from?
5. How is Vietnamese iced milk coffee prepared?

You can adjust in generate_question.py:

• top_k, top_p, temperature, no_repeat_ngram_size, repetition_penalty
