Method and system for correcting error of word input

Abstract

The invention discloses a method and a system for correcting an error of word input. The method comprises the following steps of: detecting an error input section in an encoded characteristic string input by a user; correcting the error input section in the encoded characteristic string and generating at least one error-corrected candidate character string; estimating the error-corrected candidate character string by using a noise channel model based on the encoded character string; and converting the at least one error-corrected candidate character string into an input word according to an estimation result, and displaying the input word. By the invention, the effectiveness or hit rate of error correction can be improved.

Description

technical field [0001] The invention relates to the technical field of input methods, in particular to an error correction method and system for word input. Background technique [0002] With the increasingly widespread application of technologies such as computers and the Internet, a lot of people's daily work and entertainment are carried out on computers, and users more and more frequently need to input information through computers to complete human-computer interaction. For Chinese, Japanese, Korean and other users, it is generally necessary to interact with the computer through an input method program. Take Chinese users as an example. Generally speaking, what the user inputs is a string of letters (usually pinyin of Chinese characters) or strokes and other coded strings, and the system needs to convert it into corresponding Chinese characters. [0003] However, the user may make many mistakes in the process of inputting words. The input errors involved here can be ro...

Problems solved by technology

Although this method realizes automatic error correction to a certain extent, it also has some disadvantages. For example, the error correction list is preset by default. If there is an item in the list, error correction will be forced indiscriminately, and the result after error correction will be displayed, which will make the possibility of misjudgment relatively high

For example, if the user enters the word gnome in the English input mode of the input method, if this method is used, it will be converted into ngome forcibly, and it will be directly used as the output after error correction, and this is obviously an invalid error correction result, which will affect Input fluency
