## Quick Reference

### Common Operations

```python
from semantica import Semantica
semantica = Semantica()

# Build Knowledge Graph
result = semantica.build_knowledge_base(
    sources=["doc.pdf"],
    embeddings=True,
    graph=True
)

# Extract Entities
entities = semantica.semantic_extract.extract_entities(text)

# Query Graph
results = semantica.kg.query("MATCH (n) RETURN n LIMIT 10")
```

### Configuration Reference

| Setting | Environment Variable | Config File | Default |
| :--- | :--- | :--- | :--- |
| OpenAI API Key | `OPENAI_API_KEY` | `api_keys.openai` | `None` |
| Embedding Provider | `SEMANTICA_EMBEDDING_PROVIDER` | `embedding.provider` | `"openai"` |
| Graph Backend | `SEMANTICA_GRAPH_BACKEND` | `knowledge_graph.backend` | `"networkx"` |

## Troubleshooting Guide

<div class="grid cards" markdown>

-   :material-alert: **Import Errors**
    ---
    `ModuleNotFoundError`
    
    **Solution**: Verify installation (`pip list`) and Python version (3.8+).

-   :material-key: **API Key Errors**
    ---
    `AuthenticationError`
    
    **Solution**: Set `OPENAI_API_KEY` environment variable.

-   :material-memory: **Memory Errors**
    ---
    `MemoryError`
    
    **Solution**: Use batch processing and graph stores (Neo4j).

-   :material-speedometer: **Slow Processing**
    ---
    Long processing times
    
    **Solution**: Enable parallel processing and GPU acceleration.

## Performance Optimization

### 1. Batch Processing

Process multiple documents together for better throughput.

```python
sources = ["doc1.pdf", "doc2.pdf", ..., "doc100.pdf"]
result = semantica.build_knowledge_base(sources, batch_size=10)
```

### 2. Parallel Execution

Use parallel processing for independent operations.

```python
result = semantica.build_knowledge_base(
    sources=sources,
    parallel=True,
    max_workers=8
)
```

### 3. Backend Selection

| Operation | NetworkX | Neo4j |
| :--- | :--- | :--- |
| **Graph Construction** | ⚡⚡⚡ | ⚡⚡ |
| **Query Performance** | ⚡⚡ | ⚡⚡⚡ |
| **Scalability** | Low | High |

## Security Best Practices

### API Key Management

- **DO**: Use environment variables, rotate keys regularly.
- **DON'T**: Hardcode keys, commit to version control.

### Data Privacy

- **DO**: Encrypt sensitive data, use local models.
- **DON'T**: Send PII to external APIs without protection.
