Text input method and device

Abstract

The embodiment of the invention discloses a text input method and device. According to the method, a first candidate term is determined through input words and an RNN language model, and a first character string similarity and a first word frequency score of the first candidate term are integrated to obtain a term score of the first candidate term; after an initial key code string which is input is received, surrounding characters of a target character contained in the initial key code string are determined; according to the target character and the surrounding characters, a second character string similarity between the initial key code string and all words in a dictionary is acquired; a second candidate term is determined according to the second character string similarity; and a secondcharacter string similarity and a second word frequency score of the second candidate term are integrated to obtain a term score of the second candidate term. Through the method, the problem that in the prior art, N-element language model data is sparse, and consequently recommendation precision is low is solved; and moreover, when the second candidate term is acquired through the method, the surrounding characters of the target character are considered, an error correction function can be achieved, and therefore the recommendation precision is further improved.

Description

technical field [0001] The present application relates to the technical field of input methods, in particular to a text input method and device. Background technique [0002] With the development of science and technology, a variety of terminal devices have emerged, such as mobile phones, iPads, and computers, to meet the various needs of users in work and life. In addition, users often need to input text into the terminal equipment during the process of using various terminal equipment. For example, when using the communication software installed in the terminal equipment and recording information with the terminal equipment, it is necessary to input text into the terminal equipment. [0003] When inputting text into a terminal device, generally, corresponding information is recommended to the user according to the content input by the user, so as to simplify the input steps of the user. For example, when the user inputs "happy", the terminal device may recommend multiple ...
