About the Knowledge Engineering Group
The Knowledge Engineering Group (KEG) is an informal research meta-group at the University of Economics, Prague. It overarches the research activities of the Department of Information and Knowledge Engineering (DIKE), i.e. of its four recently formed workgroups having their own websites:
- DMKD - Data Mining and Knowledge Discovery
- SWOE - Semantic Web and Ontological Engineering
- IIS - Intelligent Information Systems
- WELT - Web Engineering and Library Technology
Most of the KEG website is no longer updated and reflects the situation in 2008. Regularly updated is however the log of group highlights (the 10 most recent being in the News section below) and the calendar of KEG seminars (including the abstracts and slides of talks). Other kinds of information are assumed to appear at the workgroup websites.
There no presentations planned for the seminars in this moment. (Complete calendar is here.)
- 2016-10-16: A new PhD student, Jiří Zettel, is joining the group. He will be supervised by prof. Petr Berka and his topic will be related to data pre-processing for data mining.
- 2016-10-04: Tomáš Kliegr will give talk on association rule classification and the EasyMiner system developed by the DMKD group at the IEEE Days at the University of West Bohemia. See also: EasyMiner homepage
- 2016-09-22: pon invitation of V. Svátek, Steffen Staab is coming to give a talk at the Prague Computer Science seminar. See also: http://praguecomputerscience.cz/index.php?l=en&p=22
- 2016-09-20: Stanislav Vojíř has successfuly defended his PhD thesis “Business Rule Learning using data mining of GUHA association rules”. He remains member of our team.
- 2016-09-12 – 2016-09-16: We and a few collaborating groups enjoyed a visit of Giancarlo Guizzardi from UFES, Brazil, who among other gave a talk at the KEG seminar, and collaboration plans have been set.
