In my four years of experience in Knowledge Representation, I've focused on structuring information to enable efficient retrieval and reasoning. This involved utilizing ontologies, semantic networks, and knowledge graphs to model complex relationships between entities and concepts. Additionally, I've applied frameworks and languages such as RDF, OWL, and SPARQL to represent and query knowledge effectively. My experience in Knowledge Representation has allowed me to develop systems for data integration, artificial intelligence, and knowledge management, contributing to informed decision-making processes.
