Sakjae Lim

My name is Sakjae Lim (임석제), and I am based in Seoul, South Korea. I currently work as a Senior Researcher at LiST, where I focus on AI transformation strategy, enterprise and public-sector information systems, data architecture, and practical applications of AI, knowledge graphs, and ontology.

I have completed an M.S. in AI and Big Data at aSSIST University and am continuing my research in AI convergence engineering. My research interests are increasingly centered on applied ontology, knowledge graphs, ontology-grounded GraphRAG, neuro-symbolic AI, and AI agent systems. In particular, I am interested in how ontologies can move beyond static semantic models and support operational AI systems through concepts such as roles, tasks, policies, permissions, provenance, validation, and auditability.

I am particularly interested in the relationship between semantic ontology and operational ontology, and in how technologies such as RDF/OWL, SHACL, knowledge graphs, GraphRAG, and agent workflows can be combined to build AI systems that are more explainable, traceable, interoperable, and governable. I am also interested in applications in enterprise AI, public-sector systems, financial risk, audit, and other domains where reliable reasoning and accountability are important.

I would be very pleased to participate in the Ontolog Forum discussions, learn from researchers and practitioners in the international ontology community, and contribute perspectives from AI engineering and enterprise/public-sector applications in Korea.
