	## 📖 Usage Examples

	### Basic Sentiment Analysis

	```python
	from advanced_sentiment_analysis import AdvancedSentimentAnalyzer

	# Initialize the analyzer
	analyzer = AdvancedSentimentAnalyzer()

	# Analyze a review
	result = analyzer.analyze_review(
	"This product exceeded all my expectations! Amazing quality and fast shipping.",
	category="electronics"
	)

	print(f"Primary Sentiments: {result.primary_sentiments}")
	print(f"Emotions: {result.emotions_detected}")
	print(f"Confidence: {result.confidence_score:.2f}")
	```

	### Automated Response Generation

	```python
	from advanced_sentiment_analysis import AutomatedResponseSystem

	# Initialize response system
	response_system = AutomatedResponseSystem()

	# Process review with automated response
	result = response_system.process_review_workflow(
	"The delivery was late and the package was damaged.",
	category="logistics"
	)

	print(f"Generated Response: {result['workflow_result']['response_generated']['response_text']}")
	print(f"Action Taken: {result['workflow_result']['action_taken']}")
	```

	### Batch Processing

	```python
	from advanced_sentiment_analysis import ProductionSentimentPlatform

	# Initialize production platform
	platform = ProductionSentimentPlatform()

	# Process large dataset
	reviews_data = [
	{'review_text': 'Great product!', 'product_category': 'electronics'},
	{'review_text': 'Poor service experience', 'product_category': 'support'},
	# ... more reviews
	]

	results = platform.batch_processor.process_large_dataset(
	data_source=reviews_data,
	batch_size=100,
	output_format='json',
	save_path='results.json'
	)

	print(f"Processed {results['processing_stats']['processed_items']} reviews")
	print(f"Business Health Score: {results['aggregated_insights']['business_health_score']:.2f}")
	```

	2. Local Configuration: Use `.env` files for local development (excluded from git)
	3. Production Deployment: Use secure secret management services (AWS Secrets Manager, Azure Key Vault, etc.)
	4. Access Control: Limit API key permissions and monitor usage

	## �🔧 Configuration

	### Environment Variables

	```bash
	# Required
	OPENAI_API_KEY=your_openai_api_key

	# Optional (with defaults)
	SENTIMENT_CONFIDENCE_THRESHOLD=0.7
	ESCALATION_RATE_THRESHOLD=0.15
	PROCESSING_TIME_THRESHOLD=5.0
	ERROR_RATE_THRESHOLD=0.05
	```

	### System Configuration

	The system supports extensive configuration through the `DeploymentManager` class:

	```python
	deployment_config = {
	'environment': 'production',
	'version': '1.0.0',
	'max_concurrent_requests': 100,
	'rate_limiting': {
	'requests_per_minute': 1000,
	'burst_capacity': 50
	},
	'caching': {
	'enabled': True,
	'ttl_seconds': 300
	},
	'monitoring': {
	'metrics_collection': True,
	'alert_webhooks': ['your-webhook-url']
	}
	}
	```

	## 🔍 Monitoring & Analytics
