A data processing method applied to an artificial intelligence-based intelligent search field includes obtaining a to-be-queried text, determining, from a preset database, a to-be-queried object set corresponding to the to-be-queried text, where there is one or more to-be-queried object sets, and each to-be-queried object set includes one or more to-be-queried objects, determining relationship information of a to-be-queried object in each to-be-queried object set from preset relationship information between two objects, and determining, based on the relationship information of the to-be-queried object in each to-be-queried object set, a query field corresponding to the to-be-queried text.
