Method and device for presenting candidate character strings and training discriminant model

The invention provides a method and device for presenting candidate character strings and training discriminant models, and relates to the technical field of computers, in particular to an input method technology and a machine learning technology. According to the specific implementation scheme, a character string of alphabetic characters input by a user is obtained; the character transfer weight of the character string is determined, and the character transfer weight is used for representing the transfer probability of characters; generating a sorting weight corresponding to the character string based on a pre-acquired basic weight matched with the character string and the character transfer weight; and according to a sequence indicated by the sorting weight, selecting at least two candidate character strings matched with the character string from a pre-acquired candidate character string set for presentation. Therefore, the candidate character string matched with the character string input by the user can b
