OntoMetrics: Putting Metrics into Use for Ontology Evaluation
Birger Lantow · 2016
Automatically calculated metrics are needed in order to evaluate ontology quality. Otherwise, major resources are required in order to manually assess certain Quality Criteria of an ontology. While there is rule based support for the detection modelling errors and the violation of ontology modelling guidelines, there is a lack of support for calculating ontology metrics. However, metrics can serve as indicators for possible quality problems that are not covered rulebased ontology evaluation. Many metrics have been proposed that correlate for example with ontology characteristics like Readability, Adaptability, and Reusability. However, there is a lack of tool support. OntoMetrics provides free access to metric definition and calculation. Furthermore it fosters the development of knowledge regarding the application of Ontology Metrics. This paper provides theoretical background and usage scenarios for the OntoMetrics on-line platform.
