I will build ontologies, taxonomies, enterprise knowledge graphs and semantic layers
Francis
À propos de ce service
I am a Knowledge Graph & Ontology Engineer with a completed PhD and 10+ years of experience in data engineering, semantic technologies, and enterprise data integration.
I design semantic infrastructures that transform fragmented data into connected, machine-readable knowledge for AI, intelligent search, analytics, interoperability, and data discovery.
What I Build:
Domain ontologies using OWL, RDFS, and semantic reasoning
Enterprise knowledge graphs using RDF and graph databases
Semantic data models and ontology-driven architectures
SPARQL queries, endpoints, federated queries, and optimization
SHACL constraints for semantic validation and data quality
Ontology alignment and integration with standard vocabularies
RDF mappings from databases, APIs, JSON, and CSV
Knowledge graph foundations for RAG, GraphRAG, and LLM applications
Technical Expertise:
RDF OWL 2 RDFS SPARQL SHACL Turtle JSON-LD Stardog Neo4j GraphDB Virtuoso Python SQL
Domains:
Healthcare Life Sciences Pharmaceuticals Research Enterprise Data AI
I don't simply create ontologies. I design semantic layers that connect heterogeneous data, encode domain knowledge, enforce meaning and constraints, and make data usab

Transforming complex data into intelligent solutions! I specialize in building enterprise knowledge graphs, developing cutting-edge AI/ML models, and creating semantic ontologies. With expertise in NLP, deep learning, graph databases (Neo4j, RDF), and advanced analytics, I deliver scalable data science solutions that drive business value. Let's turn your data challenges into competitive advantages.
FAQ
What do you need from me to get started?
I need a description of your business or use case and whatever data or documentation you already have, such as databases, CSV/JSON files, APIs, existing schemas, ER diagrams, or documentation. If you are starting from scratch, I can design the semantic model from your requirements.
Can you build a knowledge graph from my existing data?
Yes. I can design the semantic model and mapping strategy for heterogeneous sources such as SQL databases, CSV, JSON, APIs, and existing RDF datasets, then structure them into a unified knowledge graph.
Can you create an ontology in OWL and RDF?
Yes. I can develop domain ontologies using OWL 2, RDFS, RDF, Turtle, and JSON-LD, including classes, properties, relationships, restrictions, axioms, and semantic constraints.
Can you integrate my knowledge graph with AI or RAG?
Yes. I can design the semantic architecture needed to connect your knowledge graph with RAG, GraphRAG, LLMs, semantic search, and AI applications, including strategies for retrieval, graph querying, and knowledge grounding.
Can you work with an existing ontology or knowledge graph?
Yes. I can review, extend, refactor, validate, align, or integrate existing ontologies and knowledge graphs. I can also work with standards and vocabularies such as FHIR, Schema.org, Dublin Core, and other domain-specific models.
