Markus Krötzsch

Markus Krötzsch is a Professor for Knowledge-Based Systems at the Institute for Theoretical Computer Science, Faculty of Computer Science, Technische Universität Dresden. He is also affiliated with TUD's Center for Advancing Electronics (cfaed) and directs the School of Embedded Composite AI (SECAI). His work bridges theoretical research and practical applications in knowledge representation and semantic technologies.

• Current Projects: Wikidata, Semantic MediaWiki, Nemo (Datalog Engine), ELK Reasoner
• Areas: Intelligent Knowledge Management, Ontology Languages, Rule-Based Reasoning

His research focuses on knowledge graphs, semantic web technologies, and rule-based systems for data integration and reasoning. He contributes to standards like OWL 2 and develops tools for collaborative data management and large-scale knowledge processing.

Recent publications highlight advancements in Datalog reasoning (2024-2025), with applications in knowledge graph querying, ontology languages, and computational logic. Keywords include semantic technologies, knowledge representation, and scalable rule engines.

He supervises students working on topics like reasoning complexity, chase algorithms, and rule-based data access. His activities include editorial roles (Area Editor of Transactions on Graph Data and Knowledge) and leadership in academic organizations like the Open Semantic Data Association.
