+# 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:** 40,000 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 `40k_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`
