This was a keynote talk given at the European Knowledge Acquisition Conference in Galway Ireland in Octover 2012.
We explore the issues and challenges that arise when building real world enterprise ontologies for large organizations. We summarize our experiences giving practical tips and guidelines concerning the following questions and issues.
• What is the purpose of the ontology?
• Where do you start?
• What do you include?
• Where does the knowledge come from?
• Do you use an upper ontology? Which one?
• What languages and tools should you use?
We look at how to represent concepts beyond the usual people, places, and time and explore how these things impact the business. These include: events and how to influence and regulate behavior; goals and intentions; skills and capabilities, registration and credentialing. Many examples will be from the Sentara Healthcare Enterprise Ontology (SHEO) a comprehensive ontology in the business of healthcare.
