Tutorial Description
This tutorial will focus on several Protégé plug-ins that have been developed specifically
for the purpose of visualizing ontologies. The first portion of the tutorial will be a hands-on walk-through
of the graph widget tutorial that is available on the Protégé Web site. The graph widget is a
custom slot widget plug-in that allows users to graphically create and populate instances of classes.
It is very useful as a) an alternative to Protégé Forms for entering instance data,
b) as a way to visualize networks of instances, and c) as a way to visualize relationships between instances. The
graph widget can be used both in the
Protégé-Frames and
Protégé-OWL
editing environments.
The second portion of the tutorial will be a demonstration of the
OntoViz,
OWLViz,
Jambalaya, and
TGVizTab tab plug-ins.
If time permits at the end of the tutorial, there will also be a demonstration of a new visualization plug-in called the
Impact & Alignment Tab, which is a
work in progress and will be released (hopefully) in the fall. The target audience for this tutorial are Protégé
users with little exposure to the existing visualization plug-ins that are currently available. If users plan to follow the
hands-on portion of the tutorial, basic experience with navigating the Protégé user interface will be assumed.
Attendees should know how to perform rudimentary tasks such as opening projects and creating new classes, slots, and
instances.
Tutorial Preparation
If you would like to follow the hands-on portion of the tutorial, please complete the following steps
prior to arrival:
- Download and install the "full"
version of Protégé 3.3.
- Download the example project that will be used for the graph widget tutorial.
- If you are new to Protégé, please familiarize yourself with basic operations such as opening projects
and creating classes, slots, and instances. The graph widget portion of the tutorial will use a frame-based ontology
in the Protégé-Frames editing environment. The most helpful resource for learning how to use this
environment is the
Getting Started with Protégé-Frames guide.
- If you want to experiment with either the OntoViz or OWLViz tabs, you need to install
Graphviz, which is 3rd party software from AT&T Research.
Once you have installed Graphviz, you need to specify in each of the tabs the location of your Graphviz installation. Instructions for doing this for OntoViz are
available on the Protege Wiki. Instructions
for doing this for OWLViz are available on page 8 of the
OWLViz Guide. Please note that this bullet item
is entirely optional and only relevant if you plan to try out the OntoViz and OWLViz tabs.
