Modeling and management of ontology-based credit evaluation meta-model

Building a proper credit evaluation model is a key factor in the construction of credit evaluation system. To solve the problems existing in the application of the credit evaluation model, this paper describes the modeling method of ontology. Then the expression of the ontology based credit evaluation meta-model applying the method is proposed. And taking zeta model as an example, the application of the ontology-based credit evaluation meta model is discussed. Ontology-based credit evaluation meta-model not only makes the credit evaluation model to be expressed and understood easily, but also provides the possibility for the sharing and reuses of credit evaluation model. A management system to maintain the ontology based credit evaluation meta-model is also introduced in the paper.
