The present invention discloses a natural expression processing method, which includes: identifying a natural expression from a user, to obtain a certain form of language information which can be processed by a computer; and converting the obtained language information to a standard expression in an encoded form. In the natural expression processing method according to the embodiments of the present invention, the natural expression may be converted into an encoded standard expression; because the conversion to the standard expression is converting the semantics of the natural expression into codes and parameters, and precise verbatim translation is not required, the requirement of accuracy for machine translation can be reduced, and meanwhile the complexity of the database for expression conversion (machine translation) is reduced, increasing data query and updating speed, and thus improving the performance of intelligent processing. In addition, the relatively simple encoded expression reduces the workload
