Tutorial Announcement: Introduction to Writing Ontologies in OWL

31 May 2011

BioHealth Informatics group at The University of Manchester are pleased to invite you to participate in their internationally renowned OWL Ontology tutorials to be hosted at the University on 11 and 12 July 2011.


This two-day introductory ‘hands-on’ workshop aims to provide attendees with both the theoretical foundations and practical experience to begin building OWL ontologies using the latest version of the Protégé-OWL tools (Protege4). It is based on Manchester's well-known "Pizza tutorial" (see CO-ODE).

This tutorial will cover the main conceptual parts of OWL through the hands-on building of an ontology of pizzas and their ingredients. A series of practical exercises take attendees through the process of conceptualizing the toppings found on a pizza; the entry of this classification into the Protégé environment; the description of many types of pizza. All this is set in the context of using automatic reasoning to check the consistency of the growing ontology and to use the reasoner to make queries about pizzas.

Since 2003 this tutorial, in various forms, has been given over 30 times and been attended by hundreds of budding ontologists.


The aims of this tutorial are to:

  • understand the use of ontologies
  • understand statements written in OWL;
  • understand the role of automatic reasoning in ontology building;
  • build an ontology and use a reasoner to draw inferences based on that ontology;
  • gain experience in the Protégé 4 ontology building environment;
  • gain insight into how OWL can play a role in semantic metadata.


  • Dr. Robert Stevens is a Reader in BioHealth Informatics in the Bio and Health Informatics Group at the University of Manchester. His main areas of research interests include: (1) the development and use of ontologies to describe biology and to make knowledge about molecular biology computationally useful; (2) communal building of ontologies - enabling domain experts to use the power of formal, expressive languages, such as the Web Ontology Language (OWL); and (3) semantic description of content through ontologies in e-Science research.
  • Dr. Georgina Moulton is a Senior Teaching Fellow at the Northwest Institute of BioHealth Informatics (NIBHI). She develops and presents Continued Professional Development courses to national and international researchers from a range of disciplines. Georgina has a background in Bioinformatics and Biochemistry.

Number of places and cost

In total there are 15 places. The cost of the course is £350 per day.
