SAFE: An LLM-as-Verifier Framework for Evidence-Grounded Multi-Hop Reasoning
✦ Why It Matters
Engineers can implement SAFE to enhance the accuracy and reliability of multi-hop QA systems.
Key Takeaways
- Implement stepwise reasoning verification in your models.
- Utilize Knowledge Graph triples for evidence grounding.
- Train verifiers under KG constraints for better data.
- Test your systems on multi-hop QA benchmarks for accuracy.
How It Works
SAFE decomposes reasoning into atomic units represented as Knowledge Graph triples, allowing for evidence-based verification of each reasoning step. During inference, an external verifier checks these steps against the provided passages, ensuring that only valid reasoning contributes to the final answer.
