Dual-Hypergraph Indexing: Bridging Knowledge Islands for Multi-Hop Reasoning in Retrieval-Augmented Generation

While hypergraph-based Retrieval-Augmented Generation (RAG) effectively captures higher-order multi-entity correlations, existing paradigms treat extracted hyperedges as isolated factual assertions. This structural fragmentation engenders rigid"knowledge islands"that bottleneck multi-hop causal inference, temporal trac...

Asymmetric Dynamic Routing: Balancing Reasoning Depth and Computational Efficiency in Hypergraph RAG

Asymmetric Dynamic Routing is proposed, an intent-conditioned retrieval framework operating over hierarchical knowledge graphs that maintains strong reasoning performance while reducing prompt token consumption and end-to-end query latency, yielding a favorable quality--efficiency trade-off for query-adaptive Hypergrap...
