Attribute oriented ontology metrics

The development of an appropriate ontology model is generally a hard task. One of the main issues is that ontology developers mainly concentrate on classes and neglect the role of attributes. The paper analyzes the role of an appropriate attribute part in providing a high level of interoperability and reusability of the constructed ontology models. In this paper, novel quality metrics are introduces and novel ontologies are evaluated. The following state-of the art metrics are introduced: Base metrics, Class axioms, Object property axioms, Data property axioms, Individual axioms, Annotation axioms, Schema metrics, Knowledgebase metrics, Class metrics, Graph metrics. In addition, own Attribute-oriented metrics are also presented. Through a total of 16 ontology systems are analyzed, which were downloaded from github.
