If you think that getting your head around OWL is a challenging experience, you have found the right tutorial. There are really just a few foundational building blocks that everything else is built from:
- individual things -- e.g. JaneDoe
- kinds of things -- e.g. Organization
- kinds of relationships -- e.g. worksFor
That's pretty much it.
In this tutorial we will describe the many ways that these things can be combined and used. Most importantly, there are triples that assert relationships between things -- e.g. JaneDoe worksFor Microsoft. There is inference to generate new triples and a few more key things, but not as much as you think. The topics we will cover include:
- OWL building blocks: Individuals, Classes and Properties
- OWL restrictions made intelligible
- Triples: everything is represented as a triple
- The role of inference
- ABox and TBox: roughly synonymous with data and metadata
- Boolean combinations: Union, Intersection and Complement
- Common patterns for building ontologies
- Common pitfalls when learning OWL
If you are getting started in OWL, this tutorial has everything you need and nothing you don't.
Michael Uschold has over two decades experience in developing and transitioning semantic technology from academia to industry. He pioneered the field of ontology engineering, co-authoring the first paper and giving the first tutorial on the topic in 1995 in the UK. As a senior ontology consultant at Semantic Arts from October 2010, Michael trains and guides clients to better understand and leverage semantic technology. He has built commercial enterprise ontologies in digital asset management, finance, healthcare, legal research, consumer products, electrical devices, manufacturing and corporation registration.
From 2008-2009, Uschold worked at Reinvent on a team that developed a semantic advertising platform that substantially increased revenue. As a research scientist at Boeing from 1997-2008 he defined, led and participated in numerous projects applying semantic technology to enterprise challenges. He is a frequent invited speaker and panelist at national and international events, and serves on the editorial board of the Applied Ontology Journal. He received his Ph.D. in AI from Edinburgh University in 1991 and an MSc. from Rutgers University in Computer Science in 1982.
Dave McComb has over 30 years of experience with enterprise level systems and enterprise architecture. He has built enterprise ontologies for over a dozen major enterprises.
