Beyond Chunk-Local Extraction: Cross-Chunk Graph Augmentation for GraphRAG 事件

Beyond Chunk-Local Extraction: Cross-Chunk Graph Augmentation for GraphRAG arXiv:2605.28004v1 Announce Type: new Abstract: GraphRAG extends retrieval-augmented generation by organizing corpora as explicit knowledge graphs, enabling graph-based retrieval for complex question answering. However, existing frameworks extract entities and relations within individual chunks, leaving cross-chunk relations -- those whose evidence spans multiple passages -- systematically absent from the index.
