Rules for Ontology Level Expression in Product Data

Although there already exist many solutions on how to build product ontology, little research has been undertaken on the quality evaluation of these models. Following the analysis of the role played by ontology in product knowledge expression stack, a two-layer evaluation discipline for product ontology is proposed based on the ontology theory in the sense of analytical philosophy. One layer is to restrict the arbitrary usage of model language's semantic expression power, the other one is to normalize the ontology model structure through meta-property analysis.
