Ontologies
An ontology is a precise specification of a conceptual understanding of a domain of interest. Their building blocks, namely objects (entities occurring in the domain), classes (groups of objects) and roles (relationships between objects and classes), can be expressed either formally or informally through both graphical and syntactic formalisms.
Formal ontologies are the foundational building blocks of Tim Berners-Lee’s vision of the Semantic Web – a proposal to structure content on the World Wide Web to facilitate machine understanding of said content.
The Web Ontology Language (OWL) became a W3C recommendation in 2004 for representing ontologies on the Semantic Web. OWL has a formal syntax and semantics that enables automated inference from OWL-expressed knowledge. This automated inference opens up a world of applications and utility across the AI landscape.
In this workshop, we will explore what formal ontologies are, what their building blocks are and how to build and maintain them using the prominent ontology development environment (ODE) – Protégé. We will also explain the mechanics of reasoning with ontologies and we will demonstrate the utility of ontologies and reasoning to solve problems in data-driven domains.
