Knowledge Graphs & Linked Data

Knowledge Graphs for AI

Large language models are powerful, but they guess. We connect your AI assistants and chatbots to a knowledge graph built from your own data. Answers become accurate, up to date and traceable to their source.

What you get

AI answers you can trust and explain

  • GraphRAG and knowledge-grounded chatbots
  • Fewer AI "hallucinations" and answers you can explain
  • Works with your existing data and your preferred AI provider

Your data

Spreadsheets, databases, documents

Knowledge graph

Connected, validated entities

AI assistant

Linked Data Strategy & Hosting

We help you model, structure, publish and host linked data, with a realistic budget in mind. Topics include choosing a triple store, data modelling and ontology design, publishing pipelines, and the trade-off between hosting it yourself and using a managed service.

Ontology Engineering

An ontology is the shared vocabulary that lets your data and systems understand each other. We design new ontologies, extend existing ones, and align them with established standards so you don't reinvent the wheel.

  • Ontology design & documentation (OWL, SKOS)
  • Data quality rules and validation (SHACL)
  • Alignment with schema.org, Wikidata, DBpedia and domain standards

Data Migration to Linked Data

Spreadsheets, databases, JSON and APIs: we turn the data you already have into a clean, connected knowledge graph. The pipelines we build are repeatable, documented and yours to keep.

  • Mapping from CSV, relational and JSON sources (RML / R2RML)
  • Automated, re-runnable ETL pipelines
  • Entity linking to public knowledge graphs, powered by our Grafio Sheets technology

Managed Knowledge Graph Hosting

Don't want to run servers? We host, monitor and back up your triple store and SPARQL endpoint, so you can focus on your data.

  • Secure, EU-hosted infrastructure
  • Monitoring, backups and updates included
  • Public or private endpoints
