A Metric Suite for Evaluating Cohesion and Coupling in Modular Ontologies

Abstract

In this paper, we present a set of semantic metrics for measuring cohesion and coupling in modular ontologies. For defining these metrics, we consider the semantic of modular ontologies instead of their syntax. Based on the semantic-based definitions, both explicitly asserted knowledge and the implied knowledge that is derived from the explicitly represented knowledge are considered for ontology evaluation. We validate the introduced metrics based on the Kitchenham metric validation framework.
