# HVU_QA

**HVU_QA** is a project dedicated to sharing datasets and tools for **Question Generation Processing (NLP)**, developed and maintained by the research team at **Hung Vuong University (HVU), Phu Tho, Vietnam**.  
This project is supported by **Hung Vuong University, Phu Tho, Vietnam**, with the aim of advancing research and applications in low-resource language processing, particularly for the Vietnamese language.

---

## 📚 Overview

This repository enables you to:

1. Fine-tune the [VietAI/vit5-base](https://huggingface.co/datasets/DANGDOCAO/GeneratingQuestions) model on your own GQ dataset.
2. Generate multiple, diverse questions given a user-provided text passage (context).

---

## 📁 Datasets

* Built following the **SQuAD v2.0 standard**, ensuring compatibility with NLP pipelines.
* Includes tens of thousands of high-quality **Question–Context–Answer triples (QCA)**.
* Suitable for both **training** and **evaluation**.

---

## 📁 Vietnamese Question Generation Tool

A **command-line tool** for:

* **Fine-tuning** a question generation model.
* **Automatically generating questions** from Vietnamese text.

Built on **Hugging Face Transformers (VietAI/vit5-base)** and **PyTorch**.

---

## Features

* Fine-tune a question generation model with SQuAD v2.0 format data.
* Generate diverse and creative questions from text passages.
* Flexible generation parameters (`top-k`, `top-p`, `temperature`, etc.).
* Simple command-line usage.
* GPU support if available.

## 📊 Evaluation Results

We conducted both **manual evaluation** (500 samples) and **automatic evaluation** (1,000 samples).

| Evaluation Type  | Precision | Recall | F1-Score |
|------------------|-----------|--------|----------|
| Automatic (1000) | 0.85      | 0.83   | 0.84     |
| Manual (500)     | 0.88      | 0.86   | 0.87     |

➡️ The model generates diverse, grammatically correct, and contextually appropriate questions.

---

## Creation Process

The dataset was built using a **4-stage automated pipeline**:

1. Select relevant QA websites from trusted sources.
2. Automatic crawling to collect raw QA pages.
3. Semantic tag extraction to obtain clean Question–Context–Answer triples.
4. AI-assisted filtering to remove noisy or inconsistent samples.

---

## 📝 Quality Evaluation

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

* **BLEU Score**: 90.61
* **Semantic similarity**: 97.0% (cosine ≥ 0.8)
* **Human evaluation**:
  * Grammar: **4.58 / 5**
  * Usefulness: **4.29 / 5**

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

## ⚙️ Setup

### 🛠️ Step 1: Download and Extract

1. Download `HVU_QA.zip`
2. Extract into a folder, e.g.:

   ```
   D:\your\HVU_QA
   ```

### 🛠️ Step 2: Add to Environment Path (if needed)

1. Open **System Properties → Environment Variables**
2. Select `Path` → **Edit** → **New**
3. Add the path, e.g.:

   ```
   D:\your\HVU_QA
   ```

### 🛠️ Step 3: Open in Visual Studio Code

```
File > Open Folder > D:\HVU_QA
```

### 🛠️ Step 4: Install Required Libraries

Open **Terminal** and run:

#### Windows (PowerShell)

**Required only**

```powershell
python -m pip install --upgrade pip
pip install torch transformers datasets scikit-learn sentencepiece safetensors
```

**Required + Optional**

```powershell
python -m pip install --upgrade pip
pip install torch transformers datasets scikit-learn sentencepiece safetensors accelerate tensorboard evaluate sacrebleu rouge-score nltk
```

#### Linux / macOS (bash/zsh)

**Required only**

```bash
python3 -m pip install --upgrade pip
pip install torch transformers datasets scikit-learn sentencepiece safetensors
```

**Required + Optional**

```bash
python3 -m pip install --upgrade pip
pip install torch transformers datasets scikit-learn sentencepiece safetensors accelerate tensorboard evaluate sacrebleu rouge-score nltk
```

✅ Verify installation:

* Windows (PowerShell)

```powershell
python -c "import torch, transformers, datasets, sklearn, sentencepiece, safetensors, accelerate, tensorboard, evaluate, sacrebleu, rouge_score, nltk; print('✅ All dependencies installed correctly!')"
```

* Linux/macOS

```bash
python3 -c "import torch, transformers, datasets, sklearn, sentencepiece, safetensors, accelerate, tensorboard, evaluate, sacrebleu, rouge_score, nltk; print('✅ All dependencies installed correctly!')"
```

---

## Usage

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

### Training (Fine-tuning)

When you run `fine_tune_qg.py`, the script will:

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

Run:

```bash
python fine_tune_qg.py
```

### Generating Questions

```bash
python generate_question.py
```

**Example:**

```
Input passage:
Iced milk coffee (Cà phê sữa đá) 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?
