Abstract: Ontology is a key component of the semantic web. The web ontologies facilitate users to espouse a common understanding of the structure of knowledge in an application domain, enabling sharing of knowledge meaningfully on the web. The increasing use of the semantic web has escalated the demand for ‘competent’ ontologies, i.e., ontologies that can effectively support their purpose of use. Hence, we regard competency as an important quality that must be assessed when evaluating ontologies being built or adapted. The competency evaluation is a semantic analysis performed by a user to ascertain if the existing ontological commitments are adequate to support the ontology’s needs and requirements. The detail analysis inevitably needs to inspect the concepts defined in the ontology and trace the relationships that exist between them. Evaluating ontologies in this manner is a challenging task because it is cumbersome to trace the intricate conceptual relationships from within the ontology editors. Although some ontology editors provide visualisation support; it is still difficult to trace the conceptual relationships on the miniaturised representation of rich and large ontologies. In an attempt to circumvent this problem, we have developed a competency evaluation tool for the Protégé ontology editor that complements an ontology developer. The tool is currently equipped with only basic features, yet has demonstrated its potential as a useful tool support for competency evaluation of web ontologies.
