Is an Upper Ontology Useful?

Ontologies play a fundamental role in information integration using semantic technologies. Whilst most ontologies are specific to a single domain, other ontologies provide a level of integration for these domain-specific ontologies and should be the starting point of any domain ontology work. They are referred to as 'upper ontologies'. This presentation will consider the benefits of using an upper level ontology and illustrate how they might be deployed in everyday use.
