JessTab Tutorial at the 10th Intl. Protégé Conference

Presenters: Henrik Eriksson, Linköping University and Karl-Heinz Krempels, RWTH Aachen University
Time: Tuesday, July 15th, 2007 at 2:00 to 5:30
Location: Hotel Benczúr, Budapest, Hungary

Description

This tutorial will introduce the JessTab extension, which enables the use of the Java Expert System Shell (Jess) under Protégé. The tutorial will cover basic Jess programming, rule-based reasoning with Jess under Protégé, and the use of Jess for managing Protégé ontologies and knowledge bases. Furthermore, the tutorial will address the mapping of instances in Protégé knowledge bases to Jess facts and use of the JessTab with both Protégé-Frames and Protégé-OWL. The tutorial will exemplify practical uses of Jess together with Protégé and discuss common design patterns. The tutorial will demonstrate how to install Jess and the JessTab and how to interact with the JessTab. The target audience is developers interested in combining ontologies and reasoning. No prior knowledge of Jess or the JessTab is required.
