The following tutorials were accepted after our
Call for Tutorials. Please note that this is a
tentative list and is subject to change.
- Ontology development 101 (Natasha Noy)
This tutorial will address the basic issues of ontology design. We will discuss why one would want to build an ontology
and provide a general introduction to ontology development and conceptual modeling. We will describe a simple methodology
for ontology development, and will introduce basic components of ontologies such as classes, slots, and individuals.
We will discuss common problems and solutions in designing ontologies. We will present common modelling patterns for
representing n-ary relations, part-whole relations, and others. We will use Protégé to demonstrate the
process of ontology design in practice. The tutorial will include demonstrations of selected advanced features of
Protégé, such as editing knowledge-acquisition forms, using advanced widgets, modularizing projects by
using project inclusion, and others. The target audience for the tutorial are domain experts with little or no experience
in ontology design or Protégé.
- OWL Tutorial I (Nick Drummond, Matthew Horridge, Holger Knublauch)
OWL is the W3C standard ontology language for the Semantic Web, and Protégé-OWL the most widely used
editing tool for OWL. This beginner's tutorial introduces OWL ontology development with Protégé. We will
explain the basic language elements of OWL (classes, properties and individuals) and show how they can be edited with
Protégé. We will then explore more complex OWL class descriptions by showing how different types of
restrictions can be used to enhance the logical meaning of classes, after which we will discuss the important notion
of primitive and defined classes. One of the key features of OWL is that it is underpinned by Description Logics,
meaning that it has well understood formal semantics. This makes it possible to use a Description Logic reasoner as
an aide in constructing an ontology, checking class consistency and computing an inferred class hierarchy.
Attendees will be exposed to this functionality throughout the tutorial, and we will provide a basic introduction to
reasoning. More details on reasoning can be acquired in the advanced afternoon tutorial. We will also walk through
selected other features of Protégé-OWL, including ontology visualization. Finally, we will illustrate how
OWL ontologies can be used to drive the development of Semantic Web applications. Slides from related tutorials can be

Advanced reasoning with OWL (Olivier Dameron, Kaustubh Supekar)
The goal of this tutorial is to leverage the reasoning capabilities of OWL. We will rely on the semantics of
Description Logics to explain the principles of reasoning by classification. On this base, we will see how the
expressivity of OWL constructs can be used (1) to represent knowledge, (2) to organize your concepts by classification,
(3) to ensure that the ontology is correct, and (4) to make ontology maintenance easier. This tutorial is intended to
be a complement to the basic OWL Plugin tutorial. The session will mainly rely on hands-on exercices, so the practical
aspect will be tackled. However, the main message of this tutorial will definitely be about "what to do?" rather than
about "where to click?".
- Application development with Protégé (Samson Tu, Ray Fergerson)
This tutorial is designed to answer the question: "I built an ontology in Protégé, now how do I use it
in my application?" It discusses architectural design issues in application development, walks through some of the
high-level tools (e.g., JessTab and Algernon) that are available, and analyzes some real, deployed applications that were
built using Protégé. The target audience of the tutorial includes managers and developers who need an
overview of the issues and approaches that are available for application development with Protégé.
The focus is not on code development.
- Protégé Plug-in Development (Ray Fergerson)
This tutorial will focus on the ways that Protégé can be extended with plug-ins. We will cover all plug-in
types including the revised import/export plug-in types that became available in Protégé 3.1. The target
audience includes both Java programmers and non-programmers. Much of the tutorial will be about conceptual issues,
capabilities, limitations, and packaging. We will cover Java programming issues and code examples will be presented but
there will be little emphasis on the actual writing of Java code. No previous experience developing Protégé
extensions is assumed. Attendees should come away with a good idea of what can be done and how difficult it is to do it.
- Managing ontology life-cycle in Protégé (Samson Tu, Jennifer Vendetti)
The basic Protégé interface allows users to create, view, and edit ontologies and knowledge bases. In the life
cycle of ontology development, a user faces additional tasks, such as importing existing resources, visualizing and querying
ontologies, checking integrity constraints, comparing versions, managing multiple related ontologies for multiple users, and
exporting knowledge content. In this tutorial, we will examine how the Protégé plug-in architecture facilitates
extensions of Protégé’s core functionality to support these tasks. We will first review the different types of
Protégé plug-ins, then discuss and demonstrate options available for the various tasks in ontology life-cycle
and application development. The tutorial assumes some basic familiarity with Protégé and is designed to help
beginning and intermediate users exploit available tools to get their work done.
