New RAG approach treats knowledge order as critical, improving language model reasoning by tracking interaction sequences rather than isolated facts.

OKH-RAG (Order-Aware Knowledge Hypergraph RAG) addresses a key limitation in existing RAG systems that ignore the sequence of reasoning steps

Traditional RAG methods treat retrieved evidence as unordered sets, but real-world reasoning often depends on the temporal order of interactions

The system represents knowledge as higher-order interactions in a hypergraph with precedence structure, recovering coherent trajectories instead of independent facts

A learned transition model infers precedence relationships directly from data without manual annotation
