A Chinese error correction method, device, equipment and storage medium based on mutual information

Abstract

The invention discloses a Chinese error correction method based on mutual information. The method comprises the following steps: obtaining a target short sentence to be corrected, performing word segmentation processing on the target short sentence, obtaining a word segmentation sequence, and determining a pinyin combination sequence corresponding to the word segmentation sequence , each pinyin combination in the pinyin combination sequence corresponds to each participle in the word segmentation sequence one by one, and based on the homophone words mapped by each pinyin combination in the pinyin combination sequence, the error correction word sequence set is obtained, and the error correction word sequence set is calculated. The mutual information of each error correction word sequence, according to the size of the mutual information, determines the error correction result of the target short sentence. By applying the technical solution provided by the embodiment of the present invention, the error correction of the target short sentence can be performed according to the frequency of words and the frequency of word collocation, and the accuracy rate of Chinese error correction can be improved. The invention also discloses a mutual information-based Chinese error correction device, a mutual information-based Chinese error correction device and a computer-readable storage medium with corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of text error correction, in particular to a mutual information-based Chinese error correction method, device, and storage medium. Background technique [0002] With the rapid development of electronic publishing, Chinese automatic proofreading technology has also been greatly developed. Among them, the pinyin error correction technology has played an important role in promoting the development of Chinese automatic proofreading technology. [0003] In recent years, pinyin error correction technology mainly relies on the acquisition of large-scale corpus and the generation of a certain number of corpora, and then based on the corpus, the texts that need to be corrected are matched and compared. Propose the most reasonable and correct word or words according to the frequency of the words. [0004] The existing pinyin error correction may ignore grammatical errors when dealing with word collocation errors, ma...
