Summary
👤
Senior🎓
Top SchoolSzymon Klarman is a senior research and engineering leader specializing in knowledge engineering and enterprise knowledge graphs, currently shaping SPOT Enterprise Knowledge Graph strategy at S&P Global. With a PhD in Computer Science and over 15 years in R&D, he blends formal logic, semantics, and probabilistic methods to deliver production-grade ontologies, taxonomies, and metadata architectures. He has built and led teams across industry and international projects—from DARPA-backed biomedical knowledge assembly to the UN’s linked open SDG taxonomy—and champions composite AI that combines symbolic and statistical approaches. Technically fluent across RDF/OWL, SPARQL, GraphQL, major graph stores and NLP toolkits, he is equally comfortable designing conceptual models and driving implementation roadmaps. A less obvious strength is his track record of translating academic-grade formalisms into pragmatic products and open-source tools (e.g., HyperGraphQL) that bridge linked data with mainstream developer ecosystems.
