Abstract
A method-to-derive-attribute-value is set of a procedure inherent to an attribute for deriving an attribute value at each attribute defined in each class in knowledge base. A data-for-value-derivation referred by the set method-to-derive-attribute-value is set at each class defined or inherited by the attribute independently from the method-to-derive-attribute-value. The attribute value is derived by referring to the data-for-value-derivation to be input as the specification of the instance by executing the method-to-derive-attribute-value when the instance is prepared as novel or altered, to thereby set the attribute value of each attribute of the instance.
