2. Collaborate with stakeholders to understand domain requirements and translate them into semantic models.
3. Maintain and evolve baseline ontologies to support ongoing and future supply chain initiatives.
4. Ensure semantic consistency and interoperability across data sources and systems.
5. Document ontology structures, relationships, and usage guidelines.
6. Work with tools such as Protégé, WebProtégé, and TopBraid Composer to manage and visualize ontologies.
7. Support integration of ontologies into data pipelines and AI systems.
Required Qualifications
8. Proven experience in ontology development using RDF, OWL, SKOS, and JSON-LD.
9. Strong understanding of semantic technologies and linked data principles.
10. Hands-on experience with ontology modeling tools (, Protégé, TopBraid Composer).
11. Deep knowledge of supply chain concepts and data structures.
12. Ability to work independently and deliver high-quality semantic models under tight timelines.
13. Excellent communication and documentation skills.
Preferred Qualifications
14. Experience integrating ontologies into AI or machine learning workflows.
