   - Verifies setup completeness

### Modified Files:

1. **`requirements.txt`** - Added:
   - `gradio` - Main UI framework
   - `streamlit` - Alternative UI framework

## 🎯 Key Features

### Classification Display
- ✅ Shows query type (Medical/Administrative/Other)
- ✅ Confidence scores with visual indicators
- ✅ Color-coded results

### Document Retrieval
- ✅ Retrieves top N relevant documents (1-50)
- ✅ Shows BM25, Dense, and RRF scores
- ✅ Displays document preview with full metadata
- ✅ Optional reranker for better accuracy

### User Experience
- ✅ Clean, professional design
- ✅ Example queries for easy testing
- ✅ Formatted and raw JSON views
- ✅ Responsive layout
- ✅ Real-time processing

## 🚀 Quick Start (TL;DR)

```powershell
# 1. Install dependencies
pip install -r requirements.txt

# 2. Build data (if needed)
python -m adapters.build_corpora

# 3. Launch UI (choose one)
python app.py              # Gradio (recommended)
streamlit run app_streamlit.py  # Streamlit (alternative)
```

## 🌟 Which UI to Use?

### Use Gradio (`app.py`) if you want:
- Quick setup and deployment
- Clean, minimal interface
- Easy sharing (public links)
- Automatic REST API
- Better for demos and presentations

### Use Streamlit (`app_streamlit.py`) if you want:
- More interactive controls
- Sidebar with settings
- More customization options
- Data-science focused interface

**Recommendation:** Start with **Gradio** - it's simpler and looks very professional!

## 📊 How It Works

```
User Input → Gradio/Streamlit Interface
    ↓
Classifier (classify query as medical/admin/other)
    ↓
If Medical → Retriever (BM25 + Dense + RRF)
    ↓
Optional Reranker (cross-encoder)
    ↓
Display Results (formatted cards + JSON)
```

## 🎓 For Your Presentation

### Demo Flow:
1. **Open the interface** - Show the clean design
2. **Enter a medical query** - e.g., "I have a rash on my hands"
3. **Show classification** - Highlight confidence scores
4. **Display results** - Show retrieved medical documents
5. **Try administrative query** - Show different handling
6. **Toggle settings** - Demonstrate reranker and result count
7. **Show JSON view** - For technical audience

### Key Talking Points:
- "We built a user-friendly web interface using Gradio"
- "The system classifies queries in real-time with confidence scores"
- "For medical queries, it retrieves relevant research from PubMed and Miriad"
- "Uses hybrid search combining BM25 and dense embeddings"
- "Optional reranker for improved accuracy"

## 🎨 Customization Options

### Change Theme/Colors
Edit the CSS in `app.py`:
```python
custom_css = """
.header {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
}
"""
```

### Add More Example Queries
Edit the `examples` list in `app.py`:
```python
gr.Examples(
    examples=[
        ["Your custom query here"],
    ],
    inputs=query_input,
)
```

### Change Port
```python
demo.launch(server_port=8080)  # Default is 7860
```

### Enable Public Sharing
```python
demo.launch(share=True)  # Creates 72-hour public link
```

## 🔧 Technical Details

### Gradio Version
- Framework: Gradio 4.x
- Features: Blocks API, custom CSS, examples, tabs
- Auto-generates REST API at `/docs`

### Streamlit Version
- Framework: Streamlit
- Features: Sidebar, caching, progress bars, metrics
- More suitable for data exploration

### Integration
- Uses existing classifier and retriever modules
- No changes to core logic
- Models loaded once and cached
- Async processing for better UX

## 🐛 Common Issues & Solutions

### "Module not found: gradio"
```powershell
pip install gradio
```

### "No corpora files found"
```powershell
python -m adapters.build_corpora
```

### Models take long to load
- This is normal on first run
- Models are cached after initial load
- Consider using smaller models for faster demo

### Port already in use
- Change port in `app.py` (line ~255)
- Or kill the process using that port

## 🌐 Deployment Options

### Local (Current Setup)
- Best for development and demos
- Access via localhost

### Hugging Face Spaces (Free)
- Free hosting for Gradio apps
- Easy to deploy
- Public URL

### Cloud Platforms
- AWS, Google Cloud, Azure
- More control and scalability
- Requires more setup

## 📈 Future Enhancements
