The method further includes aligning a plurality of attributes with a same semantics in the first attribute set to a same attribute, to generate a second attribute set associated with the entity type, attributes in the second attribute set having different semantics. The method further includes constructing the data model associated with the entity type based on the entity type and the second attribute set.
