US 10,242,296 B2 · Method and device for realizing chinese character input based on uncertainty information

Abstract

The present invention provides a method and device for realizing Chinese character input based on uncertainty information, wherein the method comprises: receiving input information from a user; extracting at least two types of uncertainty information of Chinese characters to be input, from the input information; and, determining the matched Chinese characters according to the at least two types of uncertainty information and outputting the matched Chinese character(s). The device comprises a receiving module, an extracting module and a matching module. The method and device as provided by the present invention allow a user who has incomplete memory of pronunciation or glyph information of Chinese characters to be input to realize correct input of the Chinese characters by defining a certain range for candidate characters corresponding to the Chinese characters to be input, in combination with at least two types of the extracted uncertainty information of the Chinese characters to be input.

A method for providing Chinese character based on handwriting input, comprising:

receiving a text string including one or more Chinese characters, one or more phonetic alphabets and one or more blanks from a handwriting input interface, wherein the one or more phonetic alphabets and/or the one or more blanks correspond to one or more uncertain Chinese characters;
recognizing information on the one or more Chinese characters;
extracting at least two types of uncertainty information on the uncertain Chinese characters based on the information on the one or more Chinese characters, wherein each of the at least two types of uncertainty information has a predetermined priority respectively;
determining certain Chinese characters each of which corresponds to each of the uncertain Chinese characters according to at least two types of language models based on the at least two types of uncertainty information by matching the certain Chinese characters in a sequence according to the predetermined priority, wherein each of the language models is scored by scoring a Chinese character language model or scoring a phonetic alphabet language model;
and
outputting the certain Chinese characters.
