A knowledge of basic logic; Java programming
The unit will provide students with a theoretical and practical understanding of leading edge solutions for the Semantic Web. It will introduce students to the W3C standard Web Ontology Language, OWL, and its underlying Description Logics. It will provide students with experience using a set of established patterns for developing OWL ontologies and help them to learn to avoid the major pitfalls in using OWL. It will give them an opportunity to become familiar with a widely used environment for developing and an API for applying OWL ontologies, and making use of reasoning services accessible via both.
OverviewOntologies provide rich, expressive vocabularies of terms describing a domain (e.g. medicine, astronomy, music etc.) They are key to development of the next generation of the Web, support a number of activities such as information exchange, data integration and search. This unit will provide an introduction to OWL, a standardised language for the representation of ontologies. It will cover the syntax and semantics of the language; authoring ontologies (including the use of standard design patterns); the use of reasoning and the use of ontologies in applications.
