From Local to Global: A Graph RAG Approach to Query-Focused Summarization

Catalog evidence and recorded chart appearances. Inclusion is not an endorsement.

Source snapshot imported 2026-10-20. This is not a live feed. Source and contributions.

Evidence and limits

Finding: Graph-based community summaries improved reported comprehensiveness and diversity over conventional RAG for global questions over large corpora.

Impact: Watch global-versus-local retrieval modes. Reject model-generated graph structure or summaries as canonical repository truth.

Boundary: This is a builder-authored preprint with model-based evaluation. Next: can independent evaluators reproduce gains while tracing each synthesis claim to versioned sources?

Flags: builder-authored; model-generated graphs and judges

Record State: Catalog review recorded; not a performance endorsement

What was reviewed: Structure and relevance screened; not a full evaluation
