# SafeVixAI Dataset Hub πŸ›‘οΈ
> The **Intelligence Layer** for the SafeVixAI platform β€” IIT Madras Road Safety Hackathon 2026
This repository hosts all datasets, pre-trained models, notebooks, and **reproducible data acquisition scripts** that power the SafeVixAI application. It is designed to be cloned directly into Google Colab or any research environment.
**Main Application Repo:** [SafeVixAI/SafeVixAI](https://github.com/SafeVixAI/SafeVixAI)
---
## ⚑ Quickstart (Google Colab)
```python
# Clone the entire intelligence layer
!git clone https://huggingface.co/datasets/SafeVixAI/SafeVixAI-Dataset-Hub /content/data
# Symlink into the app structure
import os
os.makedirs("/content/SafeVixAI/chatbot_service", exist_ok=True)
!ln -sfn /content/data/data/chatbot_service/data /content/SafeVixAI/chatbot_service/data
```

## πŸ”¬ Scripts β€” Reproducible Data Pipeline
The `scripts/` folder mirrors the main application's data acquisition pipeline.
All scripts here are **pure Python** β€” they run without any database or backend stack.

### Running the Scripts
```bash
# 1. Setup Kaggle auth (one-time)
pwsh scripts/scripts/data/setup_kaggle.ps1
# 2. Fetch all emergency service GIS data (Pro versions recommended)
python scripts/chatbot_service/data/fetch_hospitals.py
python scripts/chatbot_service/data/fetch_police.py
python scripts/chatbot_service/data/fetch_ambulance.py
python scripts/chatbot_service/data/fetch_blood_banks.py
python scripts/chatbot_service/data/fetch_fire.py
# 3. Download legal documents
python scripts/scripts/data/download_legal_pdfs.py
# 4. Extract MoRTH accident tables
python scripts/scripts/data/extract_morth2022_tables.py
# 5. Verify everything
python scripts/scripts/data/verify_data.py
```
> **Note:** `chatbot_service/data/` versions of the fetchers are the **Pro versions** β€” they include retry logic, exponential backoff, and more precise Indian GIS selectors.

## πŸ““ Research Notebooks β€” Open in Colab
> We advise running all notebooks through **Google Colab** for the easiest setup. Colab gives you a free T4 GPU with 16 GB of VRAM. All notebooks were built and tested on Colab, so it is the most stable platform. Any other cloud provider should work too.
