LLM Extraction

LLM extraction turns document content into typed edges for graph enrichment.

What this page covers

Provider selection, model configuration, and practical flags for tuning graph quality.

Core workflow

1. Enable extraction:

export EXTRACTION_ENABLED=true

2. Choose provider/model:

export EXTRACTION_PROVIDER=openai
export EXTRACTION_MODEL=gpt-4o-mini

3. Run graph refresh if relationships were sparse:

pgm-admin reextract --type document --no-edges-only

4. Tune neighbor expansion when you need thematic links beyond explicit mentions:

export EXTRACTION_SEMANTIC_NEIGHBORS_ENABLED=true
export EXTRACTION_SEMANTIC_NEIGHBORS_MIN_SIMILARITY=0.75

Notes

• Supported providers: openai, anthropic, ollama, openai-compatible.
• Optional semantic neighbors create related_to edges from embedding similarity.
• Auto-creation is controlled via EXTRACTION_AUTO_CREATE_ENTITIES and type allowlists.
