The algorithmic partitioning of a knowledge graph into clusters of highly interconnected entities to enable hierarchical summarization in GraphRAG. It trades high pre-computation costs and graph complexity for the ability to answer 'global' questions across an entire dataset that standard RAG cannot address.

Definition

The algorithmic partitioning of a knowledge graph into clusters of highly interconnected entities to enable hierarchical summarization in GraphRAG. It trades high pre-computation costs and graph complexity for the ability to answer 'global' questions across an entire dataset that standard RAG cannot address.

Disambiguation

Distinct from vector-based clustering; it relies on graph topology (edges) rather than just embedding proximity.

Visual Metaphor

"A multi-level city map where neighborhoods are defined by the density of footpaths between buildings rather than administrative borders."
