+
+## Usage Examples
+
+### Programmatic Usage
+
+```python
+from apps.ai_engine.services import AIEngineService
+
+# Analyze text
+result = AIEngineService.sentiment.analyze_text(
+ text="The service was excellent!",
+ language="en"
+)
+
+# Analyze and save to database
+from apps.complaints.models import Complaint
+
+complaint = Complaint.objects.get(id=some_id)
+sentiment_result = AIEngineService.sentiment.analyze_and_save(
+ text=complaint.description,
+ content_object=complaint
+)
+
+# Get sentiment for object
+sentiment = AIEngineService.get_sentiment_for_object(complaint)
+
+# Get statistics
+stats = AIEngineService.get_sentiment_stats()
+```
+
+### API Usage
+
+```bash
+# Analyze text
+curl -X POST http://localhost:8000/ai-engine/api/analyze/ \
+ -H "Content-Type: application/json" \
+ -H "Authorization: Bearer YOUR_TOKEN" \
+ -d '{
+ "text": "The service was excellent!",
+ "language": "en"
+ }'
+
+# Get statistics
+curl http://localhost:8000/ai-engine/api/sentiment-results/stats/ \
+ -H "Authorization: Bearer YOUR_TOKEN"
+```
+
+## Integration with Other Apps
+
+### Complaints Integration
+To auto-analyze complaints when created:
+
+```python
+# In apps/complaints/models.py or signals
+from apps.ai_engine.services import AIEngineService
+
+def analyze_complaint(complaint):
+ """Analyze complaint sentiment"""
+ AIEngineService.sentiment.analyze_and_save(
+ text=complaint.description,
+ content_object=complaint
+ )
+```
+
+### Feedback Integration
+To auto-analyze feedback:
+
+```python
+# In apps/feedback/models.py or signals
+from apps.ai_engine.services import AIEngineService
+
+def analyze_feedback(feedback):
+ """Analyze feedback sentiment"""
+ AIEngineService.sentiment.analyze_and_save(
+ text=feedback.message,
+ content_object=feedback
+ )
+```
+
+## Future Enhancements
+
+### Replace Stub with Real AI
+The current implementation uses a keyword-matching stub. To integrate real AI:
+
+1. **OpenAI Integration**:
+```python
+import openai
+
+def analyze_with_openai(text):
+ response = openai.Completion.create(
+ model="text-davinci-003",
+ prompt=f"Analyze sentiment: {text}",
+ max_tokens=100
+ )
+ return parse_openai_response(response)
+```
+
+2. **Azure Cognitive Services**:
+```python
+from azure.ai.textanalytics import TextAnalyticsClient
+
+def analyze_with_azure(text):
+ client = TextAnalyticsClient(endpoint, credential)
+ response = client.analyze_sentiment([text])
+ return parse_azure_response(response)
+```
+
+3. **AWS Comprehend**:
+```python
+import boto3
+
+def analyze_with_aws(text):
+ comprehend = boto3.client('comprehend')
+ response = comprehend.detect_sentiment(
+ Text=text,
+ LanguageCode='en'
+ )
+ return parse_aws_response(response)
+```
+
+### Celery Integration
+For async processing:
+
+```python
+# tasks.py
+from celery import shared_task
+
+@shared_task
+def analyze_text_async(text, content_type_id, object_id):
+ """Analyze text asynchronously"""
+ from django.contrib.contenttypes.models import ContentType
+
+ content_type = ContentType.objects.get(id=content_type_id)
+ obj = content_type.get_object_for_this_type(id=object_id)
+
+ AIEngineService.sentiment.analyze_and_save(
+ text=text,
+ content_object=obj
+ )
+```
+
+## Testing
+
+### Unit Tests
+```python
+from django.test import TestCase
+from apps.ai_engine.services import SentimentAnalysisService
+
+class SentimentAnalysisTestCase(TestCase):
+ def test_positive_sentiment(self):
+ result = SentimentAnalysisService.analyze_text(
+ "The service was excellent!"
+ )
+ self.assertEqual(result['sentiment'], 'positive')
+
+ def test_negative_sentiment(self):
+ result = SentimentAnalysisService.analyze_text(
+ "The service was terrible!"
+ )
+ self.assertEqual(result['sentiment'], 'negative')
+```
+
+### API Tests
+```python
+from rest_framework.test import APITestCase
+
+class SentimentAPITestCase(APITestCase):
+ def test_analyze_endpoint(self):
+ response = self.client.post('/ai-engine/api/analyze/', {
+ 'text': 'Great service!',
+ 'language': 'en'
+ })
+ self.assertEqual(response.status_code, 200)
+ self.assertIn('sentiment', response.data)
+```
+
+## Configuration
+
+### Settings
+Add to `settings.py`:
+
+```python
+# AI Engine Configuration
+AI_ENGINE = {
+ 'DEFAULT_SERVICE': 'stub', # 'stub', 'openai', 'azure', 'aws'
+ 'OPENAI_API_KEY': env('OPENAI_API_KEY', default=''),
+ 'AZURE_ENDPOINT': env('AZURE_ENDPOINT', default=''),
+ 'AZURE_KEY': env('AZURE_KEY', default=''),
+ 'AWS_REGION': env('AWS_REGION', default='us-east-1'),
+ 'AUTO_ANALYZE': True, # Auto-analyze on create
+ 'ASYNC_PROCESSING': False, # Use Celery for async
+}
+```
+
+## Permissions
+- All endpoints require authentication
+- UI views require login
+- Admin interface requires staff permissions
+
+## Performance Considerations
+- Stub implementation: ~5ms per analysis
+- Real AI services: 100-500ms per analysis
+- Use batch endpoints for multiple texts
+- Consider async processing for large volumes
+- Cache results to avoid re-analysis
+
+## Monitoring
+- Track processing times via `processing_time_ms` field
+- Monitor confidence scores for quality
+- Review sentiment distribution for bias
+- Track AI service usage and costs
+
+## Documentation
+- API documentation available via DRF Spectacular
+- Swagger UI: `/api/schema/swagger-ui/`
+- ReDoc: `/api/schema/redoc/`

+- ✅ `Inquiry.message` → Auto-analyzed on save
+
+#### 2. **Feedback App** (`apps.feedback`)
+- ✅ `Feedback.message` → Auto-analyzed on save
+- ✅ `FeedbackResponse.message` → Auto-analyzed on save
+
+#### 3. **Surveys App** (`apps.surveys`)
+- ✅ `SurveyResponse.text_value` → Auto-analyzed for text responses
+
+#### 4. **Social Media App** (`apps.social`)
+- ✅ `SocialMention.content` → Auto-analyzed on save
+- ✅ Updates `SocialMention.sentiment` field automatically
+
+#### 5. **Call Center App** (`apps.callcenter`)
+- ✅ `CallCenterInteraction.notes` → Auto-analyzed on save
+- ✅ `CallCenterInteraction.resolution_notes` → Auto-analyzed on save
+
+---
+
+## 🏷️ Template Tags for Easy Display
+
+### Created Template Tags (`apps/ai_engine/templatetags/sentiment_tags.py`)
+
+```django
+{% load sentiment_tags %}
+
+
+{% sentiment_badge complaint %}
+{% sentiment_badge feedback size='lg' %}
+
+
+{% sentiment_card complaint %}
+
+
+{% get_sentiment complaint as sentiment %}
+
+
+{% has_sentiment complaint as has_sent %}
+
+
+{{ sentiment|sentiment_badge_class }}
+{{ sentiment|sentiment_icon }}
+{{ score|format_score }}
+{{ confidence|format_conf }}
+```
+
+### Template Tag Templates
+- ✅ `templates/ai_engine/tags/sentiment_badge.html` - Badge display
+- ✅ `templates/ai_engine/tags/sentiment_card.html` - Card display
+
+---
+
+## 📍 URL Routes
+
+### UI Routes
+```
+/ai-engine/ # List all sentiment results
+/ai-engine/sentiment/{id}/ # View sentiment detail
+/ai-engine/analyze/ # Manual text analysis
+/ai-engine/dashboard/ # Analytics dashboard
+/ai-engine/sentiment/{id}/reanalyze/ # Re-analyze
+```
+
+### API Routes
+```
+GET /ai-engine/api/sentiment-results/ # List results
+GET /ai-engine/api/sentiment-results/{id}/ # Get result
+GET /ai-engine/api/sentiment-results/stats/ # Statistics
+POST /ai-engine/api/analyze/ # Analyze text
+POST /ai-engine/api/analyze-batch/ # Batch analyze
+GET /ai-engine/api/sentiment/{ct_id}/{obj_id}/ # Get for object
+```
+
+---
+
+## 🔄 How It Works
+
+### Automatic Flow
+
+1. **User creates/updates content** (e.g., complaint, feedback, survey response)
+2. **Django signal fires** (`post_save`)
+3. **AI Engine analyzes text** automatically
+4. **SentimentResult created** and linked via generic foreign key
+5. **Results available** immediately in UI and API
+
+### Example: Complaint Flow
+
+```python
+# User creates complaint
+complaint = Complaint.objects.create(
+ title="Long wait time",
+ description="I waited 3 hours in the emergency room. Very frustrated!",
+ patient=patient,
+ hospital=hospital
+)
+
+# Signal automatically triggers
+# → analyze_complaint_sentiment() called
+# → AIEngineService.sentiment.analyze_and_save() executed
+# → SentimentResult created:
+# - sentiment: 'negative'
+# - sentiment_score: -0.6
+# - confidence: 0.8
+# - keywords: ['waited', 'frustrated', 'long']
+# - linked to complaint via generic FK
+
+# Display in template
+{% load sentiment_tags %}
+{% sentiment_badge complaint %}
+# Shows: 😞 Negative
+```
+
+---
+
+## 💡 Usage Examples
+
+### In Views (Programmatic)
+
+```python
+from apps.ai_engine.services import AIEngineService
+
+# Analyze text
+result = AIEngineService.sentiment.analyze_text(
+ text="The service was excellent!",
+ language="en"
+)
+
+# Analyze and save
+sentiment = AIEngineService.sentiment.analyze_and_save(
+ text=complaint.description,
+ content_object=complaint
+)
+
+# Get sentiment for object
+sentiment = AIEngineService.get_sentiment_for_object(complaint)
+
+# Get statistics
+stats = AIEngineService.get_sentiment_stats()
+```
+
+### In Templates
+
+```django
+{% load sentiment_tags %}
+
+
+
+
+
{{ complaint.title }}
+
{{ complaint.description }}
+
+
+ {% sentiment_card complaint %}
+
+
+
+
+
+ {{ complaint.title }}
+ {% sentiment_badge complaint %}
+ |
+```
+
+### Via API
+
+```bash
+# Analyze text
+curl -X POST http://localhost:8000/ai-engine/api/analyze/ \
+ -H "Content-Type: application/json" \
+ -H "Authorization: Bearer TOKEN" \
+ -d '{"text": "Great service!", "language": "en"}'
+
+# Get statistics
+curl http://localhost:8000/ai-engine/api/sentiment-results/stats/ \
