When building RAG evaluation frameworks:

1. Define retrieval metrics (precision, recall, MRR, NDCG)
2. Design context relevance metrics
3. Implement answer faithfulness metrics
4. Create answer relevance metrics
5. Build hallucination detection
6. Design end-to-end RAG metrics
7. Implement benchmark dataset creation
8. Create evaluation pipelines with reporting

Key metrics: Context precision/recall, answer faithfulness, answer relevance, hallucination rate.

Industry standards

• RAGAS
• ARES
• TruLens
• LangChain Evaluation
• DeepEval

Best practices

• Evaluate retrieval and generation separately
• Use multiple metrics for comprehensive assessment
• Include faithfulness checks for hallucinations
• Test with diverse question types
• Create benchmark datasets for regression testing
• Monitor metrics over time for drift

Common pitfalls

• Only evaluating end-to-end without component metrics
• Using single metric for complex assessment
• Not testing faithfulness adequately
• Missing edge cases in evaluation set
• Not tracking metric trends over time
