🌐 Web Interface Integration

The evaluation system is fully integrated into the main Flask application:

• Dashboard URL: /evaluation/dashboard
• API Endpoints:
  • GET /evaluation/status - Current evaluation status
  • POST /evaluation/run - Execute new evaluation
  • GET /evaluation/results - Retrieve results
  • GET /evaluation/history - Historical data

📈 Monitoring & Alerting

Automated Alert System:

• Critical Thresholds: Success rate <90%, Citation accuracy <20%
• Warning Thresholds: Latency >6s, Groundedness <90%
• Trend Detection: Performance regression detection
• Historical Tracking: 100 evaluation history with trend analysis

🎯 Next Steps & Recommendations

Immediate Actions (1-2 weeks):

1. 🔴 Fix Citation Algorithm - Critical priority
   • Investigate citation extraction logic
   • Implement fuzzy matching for source attribution
   • Target: >80% citation accuracy

Short-term Improvements (2-4 weeks): 2. ⚡ Optimize Response Times

• Implement query result caching
• Optimize vector search performance
• Target: <3s average response time

3. 📊 Enhanced Monitoring
