Data Ontologist
About this gig
Looking to structure your data for AI, research, or a semantic web app?
I design and build clean, custom OWL ontologies using Protégé. I specialize in taking unstructured information and turning it into organized, machine-readable knowledge models that are highly scalable, easy to query, and ready for logical reasoning.
Whether you need a brand-new schema, semantic use-case mapping, or structural visualizations using OWLGrEd, I've got you covered.
What i offer:
- Ontology Development: Custom models built from scratch or integrated with existing standards like Schema.org.
- Protégé Modeling: Clean setup of class hierarchies, properties (object/data/annotation), and individuals.
- Data Retrieval: Custom SPARQL queries to test, validate, and retrieve data from your model.
- OWLGrEd Diagrams: Clear graphical visualizations of your classes and relationships so you can easily see the whole structure.
- UseCase Mapping: Structuring and populating the ontology to fit your specific system requirements.
Tools:
- Protégé, OWLGrEd, SPARQL, RDF/OWL
