ontology researchers struggle to propose various methods and methodology in ontology evaluation as reference sources for ontology engineering and evaluating process.In this paper,we intend to explain a new ontology evaluation methodology (i.e.,OntoAbsolute) which it is proposed to evaluate structural domains in semantic relations and concepts in upper,middle and lower ontologies.In 2007,a modern method was proposed in quantitative evaluation of the structural domains in knowledge organizations based on kant's epistemology.OntoAbsolute relies on the modern quantitative evalution method to evaluate simplicity and unity concepts (i.e.,metaproperties) in the structural domains in concepts and their relations via proposed criteria and related measures.OntoAbsolute has a capacity to develop new criteria and measures to access cognitive results in ontology as a whole.OntoAbsolute is similar to ontoclean in terms of domain independent feature and meta-properties usage and also OntoAbsolute consists of the same structure to classify the chararacteristics (i.e., multi-level framework) with OntoMetric.
