Theorem Proving in the Ontology Lifecycle

In this paper we present a methodology for the verification of first-order logic ontologies, and provide a lifecycle in which it may be implemented to develop a correct ontology. We discuss the need for a methodology to address development issues and illustrate the way in which this characterization of the ontology lifecycle supports the design and deployment of ontologies within software applications. Theorem proving plays a critical role in the specification of requirements, design, and verification of the ontology. We illustrate the application of theorem proving in the lifecycle using examples from the PSL Ontology.
