A Tree-based RAG Framework for Evidence-Intensive QA via Adaptive Planning and Topology-Aware Evidence Gathering
TL;DR
APT-RAG is a novel framework that enhances evidence-intensive question answering (QA) by utilizing adaptive planning and topology-aware evidence gathering, outperforming existing methods in benchmarks.
✦ Why It Matters
Implement APT-RAG to enhance your evidence-intensive QA systems and improve answer accuracy.
Key Takeaways
- Utilize adaptive planning to adjust reasoning structures dynamically.
- Implement topology-aware evidence gathering for better evidence integration.
- Adopt evidence-guided batched answer generation to reduce overhead.
- Test APT-RAG on your QA benchmarks for improved performance.
How It Works
APT-RAG enhances QA by dynamically expanding its reasoning structure based on the specific dependencies of the question. This adaptive planning allows the framework to efficiently gather and integrate evidence from various sources, leveraging sibling evidence and aggregating information from related nodes.
By focusing on the topology of the evidence, APT-RAG ensures comprehensive coverage and effective synthesis of information, which is crucial for answering complex questions.
