Translation between product classification schemas
View Patent ↗A schema translation tool ( 36 ) includes a mapping module ( 37 ) that receives information regarding a source schema ( 70 ) and a target schema ( 80 ). The source and target schemas ( 70, 80 ) each include a taxonomy that includes a hierarchy of classes ( 72, 82 ) into which products may be categorized. At least the source schema ( 70 ) further includes a product ontology, including one or more product attributes, that is associated with one or more of the classes ( 72 ). The mapping module ( 37 ) associates one or more source classes ( 72 ) of the source schema ( 70 ) with one or more target classes ( 82 ) of the target schema ( 80 ). The schema translation tool ( 36 ) further includes an ontology generation module ( 38 ) that generates a product ontology for each of the target classes ( 82 ) based on the product ontologies of the associated source classes ( 72 ).
