METHOD AND APPARATUS FOR PRESENTING CANDIDATE CHARACTER STRING, AND METHOD AND APPARATUS FOR TRAINING DISCRIMINATIVE MODEL

A method and an apparatus for presenting a candidate character string and a method and an apparatus for training a discriminative model are provided. The method for presenting a candidate character string may include: acquiring a character string of alphabetic words inputted by a user; determining a character transition weight of the character string, the character transition weight being used to characterize a transition probability of a character; generating a sort weight corresponding to the character string based on a pre-acquired basic weight matching the character string and the character transition weight; and selecting, according to an order indicated by the sort weight, at least two candidate character strings matching the character string from a pre-acquired candidate character string set for presentation.
