Evaluating ontology criteria for requirements in a geographic travel domain

An ontology is a model of a domain of knowledge. The knowledge that is captured in an ontology can be used for providing interoperability, sharing of information and reduction in semantic ambiguity in application areas such as Knowledge Management, the Semantic Web and E-Commerce. Given that each of these application areas may have differing requirements, how do we assess whether an ontology adequately addresses the requirements of a given application? In this paper, we consider how existing criteria and measures can be used to evaluate different aspects of the suitability of ontologies for application areas in the domain of travel and geography. Specifically, we consider some existing measures of coverage, as well as propose new ones, and determine whether they address the application requirement of appropriate granularity.
