RFKG-CoT: Relation-Driven Adaptive Hop-count Selection and Few-Shot Path Guidance for Knowledge-Aware QA
RFKG-CoT addresses limitations in knowledge-intensive QA by enhancing existing KG-CoT frameworks. It introduces a relation-driven adaptive hop-count selector for dynamic reasoning step adjustment and a few-shot in-context learning path guidance mechanism. This leads to significant accuracy improvements across various KGQA benchmarks, particularly with smaller LLMs, and provides more interpretable, knowledge-aware reasoning.

RFKG-CoT replaces the rigid, question-driven hop-count selection with a dynamic, relation-driven mechanism. It leverages a 'relation mask' to adaptively adjust reasoning steps based on activated Knowledge Graph relations.

Accuracy gain on CompWebQ from relation mask
The framework integrates a few-shot in-context learning strategy with Chain-of-Thought (CoT) prompting. It uses structured 'question-paths-answer' examples to guide LLMs in interpreting and utilizing reasoning paths more effectively.
| Feature | KG-CoT (Previous) | RFKG-CoT (Ours) |
|---|---|---|
| Hop-count Selection | Question-driven, static | Relation-driven, adaptive (via mask) |
| Path Interpretation | Input without explicit guidance | Few-shot CoT (think) examples for interpretation |
| Reasoning Steps | Fixed or question-intent based | Dynamically adjusted by KG structure |
| LLM Utilization | Limited | Enhanced by 'question-paths-answer' format |

Accuracy gain on WebQSP from path prompt
RFKG-CoT combines a graph reasoning model with large language models to provide robust and interpretable answers. It first generates reasoning paths on the KG and then uses these paths with few-shot prompts to guide LLMs.
Example of RFKG-CoT in Action
Scenario: Consider the question: 'What is the name of Justin Bieber's brother?'
Approach: RFKG-CoT dynamically identifies the 'brother' relation (1-hop) or 'parents → children' chain (2-hop) using its relation mask. It then constructs a path like 'Justin Bieber → parents → Jeremy Bieber → children → Jaxon Bieber' and provides it to the LLM with a 'think' prompt, guiding the LLM to identify Jaxon Bieber as the brother.
Impact: This adaptive path selection and guided interpretation significantly reduces factual errors and provides a more accurate answer compared to traditional methods that might miss multi-hop relations or misinterpret paths.
