Stepwise Reasoning Enhancement for LLMs via External Subgraph Generation

In three linesSGR integrates LLMs with external knowledge graphs via schema-guided subgraph generation. Framework extracts entities and relations, retrieves compact subgraphs, then combines direct Cypher reasoning and multi-path validation. Experiments on CWQ, WebQSP, GrailQA, KQA Pro show improved accuracy and Hits@1 over baselines.
