Pellets-based reasoning

Course	UNIK4710, UNIK9710
Title	Pellets-based reasoning
Lecture date	2013/04/05 09:15
presented	by Josef.Noll
Objective	This lecture provides an introduction to the Pellets reasoner, shows a programming example on how to run SWRL, elaborates on the capability on writing knowledge back into an ontology, and discusses the capabilities of the Semantic Query Web Rule Language (SQWRL).
Learning outcomes	Having joined the lecture, you will have understood the difference between Pellets-based reasoning and the direct application of the SWRL-tab in Protege, be able to apply Pellets for your ontology be able to mention advantages and limitations of Pellets-based reasoning list the difference between SWRL and SQWRL explain where to apply SWRL and SQWRL
Pensum (read before)	Those of you working on OWL2.0 (and Protege 4.1), please establish an example program with reading/writing from an ontology.
