Error correction method and error correction device of characters

Abstract

The invention discloses an error correction method and an error correction device of characters. The method comprises the following steps: determining coded character strings to need be performed the error correction of the characters; receiving an error correction instruction event, and determining a first coded character set to be modified in the coded character strings according to the error correction instruction event; and receiving an error correction instruction, and performing the error correction operation instructed by the error correction instruction on the first coded character set. The method and the system can improve the character error correction efficiency in the process of inputting the characters.

Description

technical field [0001] The invention relates to the field of input methods, in particular to a character error correction method and system. Background technique [0002] For Chinese, Japanese, Korean and other users, it is generally necessary to interact with the computer through an input method program: the user enters a coded string through the keyboard, and then the input method program converts it into the corresponding language according to its preset standard mapping rules options, which in turn are confirmed by the user to enter the required information. [0003] However, when people input a coded string, it is easy to input a wrong coded string, and it is difficult to obtain the candidate result required by the user. For example, for the Chinese Pinyin input method, when the user inputs the corresponding Pinyin of Chinese characters, there are mainly three types of errors that may occur: [0004] One is missing input letters, such as the user wants to input the pi...

Problems solved by technology

[0004] One is missing input letters, such as the user wants to input the pinyin "jin'tian" corresponding to the word "today" (the single quotation mark "'" in the encoded string here and later is only for viewing convenience, not input by the user) ", however, the letter "i" in "tian" is missed, so that the input result is "jin'tan";

[0005] The second is to input more letters. For example, the user wants to input "jin'tian", but enters an extra letter "n" by mistake, so that the input result is "jin'n'tian";

[0006] The third is to reverse the order of the input letters. For example, the user wants to input "jin'tian", but enters "i" before "t" by mistake, so that the input result is "jin'itan";

And when the character string entered by the user is too long and there are too many input errors in the character string, this error correction process will be more complicated, thus consuming more time for the user

Alternatively, the user can also press the Esc key or other delete keys to delete the string entered by the user as a whole, and then re-enter the correct string. However, when the string entered by the user is too long, delete the string as a whole and re-enter the correct string. The string process will also consume a lot of user time

[0009] Through the above analysis, the inventor found that: in the prior art, when the user corrects an error due to an incorrect character input, the error correction efficiency is low
