Knowledge Representation and Reasoning for the Semantic Web – OWL 2 Rules

a tutorial at KI 2009, Paderborn, Germany, September 15 2009, 9:00–12:30 a.m.

Speakers: Pascal Hitzler, Markus Krötzsch, Sebastian Rudolph

Abstract

The revision 2 of the Web Ontology Language OWL is much richer than its predecessor OWL 1.0 with respect to modelling with rules. In particular, a significant amount of rules – meaning first-order rules in the sense of the Semantic web Rule Language SWRL – can be expressed directly in OWL 2 DL. Further rules lying outside OWL 2 DL, in particular a generalization of DL-safe datalog rules, can be added while still retaining decidability and/or tractability.

This tutorial introduces the upcoming OWL 2 knowledge representation language (expected to become a W3C standard by end 2009), and relevant rules fragments and extensions in detail. It is aimed for the theoretician as well as the ontology engineer who would like to learn about the intimate relationship between OWL 2 and rules.

Slides

In this course, we focus on logical aspects of OWL and rules, using description logic syntax for introducing OWL 2. Readers who prefer a more RDF-centric view can find materials with alternative introductions to OWL 2 on our slides page.
