Verzia zo dňa a času 16:09, 23. október 2008

The KR research group at DAI, chaired by Ján Šefránek, is concerned with (mostly theoretical) research in Knowledge Representation and Reasoning(KR&R).

Group Focus

Our main interests within KR&R include:

• Non-monotonic logics and non-monotonic reasoning
• Knowledge revision
• Answer set programming
• Dynamic logic programming
• Semantic Web
• Ontologies

Group Members

• Ján Šefránek (group chair)

• Martin Baláž
• Martin Homola
• Michal Malý
• Peter Klimo
• Jozef Šiška

Activities

KR Group orgainizes irregular sessions of the KR Seminar where the group members and sometimes invited speakes present latest advances in their research.

Projects

• Surveying and improving semantic properties of distributed onotlogies. Project no. UK/365/2008 awarded by Comenius University. Narowly focused project aming at comparing differnt existing formalisms for representing distributed ontologies.
