Nodes

Fundamental units in graph structures representing entities (e.g., people, documents, concepts) connected via edges. Nodes may contain properties/attributes and form the basis of relationship modeling.

Key Applications:

• In GraphRAG, nodes represent entities (e.g., documents, key concepts) while edges encode relationships between them
• Enables context-aware retrieval beyond single-document matching
• Powering cost-effective local RAG with llama-31 via neo4j graph databases

Related Concepts:

• GraphRAG: RAG variant using graph relationships
• neo4j: Graph database used in GraphRAG implementations
• llama-31: Local LLM powering GraphRAG inference
