Problems solved by technology

[0003] In the method of text correction using noise channel theory, it is necessary to obtain the string W' that maximizes the probability of P(W)P(O|W) according to the language model. However, when the language environment and theme background of the text to be corrected are different At the same time, the same words or character strings may have different meanings, so different correction options are required, but the language model in the prior art is relatively fixed, and only fixed correction options can be used for the text to be corrected, so correction errors are prone to occur, resulting in Calibration flexibility is poor and accuracy is low

Abstract

Embodiments of the present invention provide a text correcting method and user equipment, and relate to the language processing field, which may reduce correction mistakes, and improve the correction flexibility and accuracy. The text correcting method comprises: obtaining more than two text types of a to-be-corrected text in a preset text classification standard; obtaining, in a correction knowledge base, a to-be-combined sublanguage model corresponding to each text type of the to-be-corrected text; combining the obtained more than two to-be-combined sublanguage models into a mixed language model; correcting the to-be-corrected text according to the mixed language model to obtain a correction suggestion text. The text correcting method and user equipment provided in the embodiments of the present invention are used for correcting a wrong text.

Description

technical field [0001] The present invention relates to the field of language processing, in particular to a text correction method and user equipment. Background technique [0002] With the advent of the digital age, the text correction technology to correct the wrong text to be corrected is more and more widely used. In the prior art, in the noise channel theory, it is considered that the errors of the text to be corrected mainly come from the input errors generated in the process of manual input, and the input errors generated in optical character recognition and speech recognition. In the noise channel theory, these texts to be corrected are regarded as real texts produced after passing through a channel mixed with noise. For example, W is the original string sequence <W 1 ,W 2 ,...,W n >, that is, the completely correct text, produces noise text after passing through the noise channel <O 1 ,O 2 ,...O 3 >, the method of text correction using the noise ...
