About the Knowledge Engineering Group

The Knowledge Engineering Group (KEG) is an informal research group at the University of Economics, Prague. It is centered around the Department of Information and Knowledge Engineering (DIKE) and covers most of its research activities.

This website should give you a brief overview of the research topics addressed, people involved, participation and coordination of projects, regular research seminars and KEG's publications.


There no presentations planned for the seminars in this moment.

  • 2014-05-21: David Chudán's son, Matěj, was born. Congratulations!
  • 2014-03-01: In 2014, two KEG proposals for IGA (university-level) research projects have been retained for funding. A new one is 'Semantic web data visualization exploiting the ontological schema structure', coordinated by Marek Dudáš. Furthermore, 'Research of factors affecting applicability of association rule mining algorithms', coordinated by Tomáš Kliegr, was extended from 2013 to 2014.
  • 2014-02-142014-02-16: Jirka Kosek (as PC Chair) organised the annual XML Prague conference in UEP premises. See also: XML Prague 2014 homepage

A joint UEP group, led by colleagues from the Dept. of Information Technology (but with participation of KEG) is one of the partners. See also: SharePSI 2.0 homepage
  • 2014-01-21: The web page of the first of the proposed four DIKE focused research groups, SWOE (Semantic Web and Ontological Engineering), came into being. From now on, KEG will be gradually transformed into an 'envelope' overarching the new groups and mediating their direct collaboration. See also: SWOE group page
  • 2014-01-01: Ondřej Zamazal succeeded, in a sharp competition, in obtaining a 3-year (2014-2016) post-doctoral project from the Czech Science Foundation: 'COSOL - Categorization of Ontologies in Support of Ontology Life Cycle'. Congratulation!
  • 2013-12-13: Tomáš Kliegr became father of a daughter, Anna Marie. Big congratulations!
  • 2013-11-28: The LOD2 project webinar on the ORE (Ontology Repair and Enrichment) tool, designed by University of Leipzig, featured, among other, a demo of the embedded functionality of Ondřej Zamazal's PatOMat services (a use case in naming pattern detection and transformation).

Complete list of history is available as well.
