I am an Ontologist and Semantic Web professional specializing in ontology engineering, knowledge graph modeling, and SPARQL-based semantic systems, with a strong grounding in Library and Information Science. I transform complex, unstructured domain knowledge into formally structured OWL ontologies and interoperable knowledge graphs, using methodologies such as METHONTOLOGY and YAMO. I validate models through Protégé and Apache Jena Fuseki, design SPARQL queries for semantic search and data retrieval, and apply LLM-assisted ontology development with human-in-the-loop workflows. My focus is on building semantically rich systems that improve reliable knowledge discovery, interoperability, and AI-driven reasoning.…I am an Ontologist and Semantic Web professional specializing in ontology engineering, knowledge graph modeling, and SPARQL-based semantic systems, with a strong grounding in Library and Information Science.
