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.
