# HVU_QA

**HVU_QA** is an open-source Vietnamese Question–Context–Answer (QCA) corpus, accompanied by supporting tools, created to facilitate the development of FAQ-style question generation and question answering systems, particularly for low-resource language settings. The dataset is developed by a research team at Hung Vuong University, Phu Tho, Vietnam, led by Dr. Ha Nguyen, Deputy Head of the Department of Engineering Technology. HVU_QA was constructed using a fully automated data-building pipeline that combines web crawling from reliable sources, semantic tag-based extraction, and AI-assisted filtering, helping ensure high factual accuracy, consistent structure, and practical usability for real-world applications.

## 📋 Dataset Description

- **Language:** Vietnamese
- **Format:** SQuAD-style JSON
- **Total samples:** 39,000 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

## ⚙️ Creation Pipeline

The dataset was built using a 4-stage automated process:
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 `vit5-base` model trained on HVU_QA achieved:

| Metric                 | Score           |
|-------------------------|----------------|
| BLEU                    | 89.1           |
| Semantic similarity     | 91.5% (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.

## 📁 Vietnamese Question Generation Tool

## 🛠️ Requirements

* Python 3.8+
* PyTorch >= 1.9
* Transformers >= 4.30
* scikit-learn

### 📦 Install Required Libraries

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

*(Install PyTorch separately from [pytorch.org](https://pytorch.org) if not installed yet.)*

### 📥 Load Dataset from Hugging Face Hub
```python
from datasets import load_dataset

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

* Train and evaluate a question generation model.
* Develop Vietnamese NLP tools.
* Conduct linguistic research.

### 🔹 Fine-tuning

```bash
python fine_tune_qg.py
```

This will:

1. Load the dataset from `39k_train.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](https://huggingface.co/datasets/DANGDOCAO/GeneratingQuestions/tree/main).)*

### 🔹 Generating Questions
```bash
python generate_question.py
```

**Example:**
```
Input passage:
Cà phê sữa đá là một loại đồ uống nổi tiếng ở Việt Nam
(Iced milk coffee is a famous drink in Vietnam)

Number of questions: 5
```
**Output:**
```
1. Loại cà phê nào nổi tiếng ở Việt Nam?  
   (What type of coffee is famous in Vietnam?)  
2. Tại sao cà phê sữa đá lại phổ biến?  
   (Why is iced milk coffee popular?)  
3. Cà phê sữa đá bao gồm những nguyên liệu gì?  
   (What ingredients are included in iced milk coffee?)  
4. Cà phê sữa đá có nguồn gốc từ đâu?  
   (Where does iced milk coffee originate from?)  
5. Cà phê sữa đá Việt Nam được pha chế như thế nào?  
   (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`
