Ontology Framework: Results of Ontology Summit 2007

This document presents the results and findings of the Ontology Summit 2007, focusing on the need for a framework that supports diversity without divergence in ontologies. It proposes a set of characteristics and features to distinguish different approaches, including semantic dimensions and pragmatic considerations.

  1. Ontology Framework:Results of Ontology Summit 2007 Michael Gruninger University of Toronto

  2. Ontology Summit 2007 • This is based on the communique from the 2007 Ontology Summit thattook place April 22-23, 2007 in Gaithersburg, Maryland, at the National Institute of Standards and Technology (NIST). • Contributors: • Olivier Bodenreider, Frank Olken, Leo Obrst, Peter Yim

  3. Objective • Provide a framework that ensures that we can support diversity without divergence, so that we can maintain sharability and reusability among the different approaches to ontologies. • To this end, we can define a set of characteristics common to all approaches and then propose a set of features that can be used to distinguish among different approaches.

  4. Dimensions • We can identify a set of dimensions that can be used to distinguish among different approaches to ontologies. • There are two kinds of dimensions: • Semantic - how an ontology specifies the meaning of its vocabulary • Expressiveness of the ontology representation language • Level of structure • Representational granularity • Pragmatic - the purpose and context in which the ontology is designed and used • Intended use • Role of automated reasoning • Descriptive vs prescriptive • Design methodology • Governance
