Docling Graph

What is Docling Graph?

Docling-Graph turns documents into validated Pydantic objects, then builds a directed knowledge graph with explicit semantic relationships.

This transformation enables high-precision use cases in chemistry, finance, and legal domains, where AI must capture exact entity connections (compounds and reactions, instruments and dependencies, properties and measurements) rather than rely on approximate text embeddings.

This toolkit supports two extraction paths: local VLM extraction via Docling, and LLM-based extraction using either local runtimes (vLLM, Ollama) or API providers (Mistral, OpenAI, Gemini, IBM WatsonX), all orchestrated through a flexible, config-driven pipeline.

Key Features

  • ✍🏻 Multi-Format Input: Ingest PDFs, images, URLs, raw text, Markdown and more.
  • 🧠 Flexible Extraction: VLM or LLM-based (vLLM, Ollama, Mistral, Gemini, WatsonX, etc.)
  • 🔨 Smart Graphs: Convert Pydantic models to NetworkX graphs with stable node IDs
  • 📦 Multiple Export: CSV (Neo4j-compatible), Cypher scripts, JSON, Markdown
  • 📊 Rich Visualizations: Interactive HTML and detailed Markdown reports
  • ⚙️ Type-Safe Configuration: Pydantic-based validation
