Embodiment Construction

[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0061] A kind of Chinese homonym error automatic proofreading method provided by the present invention is based on homonym confusion set and local adjacency NGram model combination judgment method with weight to carry out Chinese homonym error automatic proofreading, and the method comprises the following steps: 1), establish homonym confusion set, to Chinese Words use the pinyin of Chinese characters to establish a homonym confusion set for Chinese words.

[0062] Such as figure 1 As shown, using the pinyin table of Chinese characters and the Chinese dictionary, a confusion set of homophones is generated:

[0063] C S e t ( W i ) = { W i 1 , W...

Abstract

The present invention discloses a Chinese homonym error auto-proofreading method. The method comprises: first, generating a confusion set of Chinese homonyms; through large-scale Web corpus training, collecting statistics on a left-adjacent binary model, a right-adjacent binary model, and an adjacent ternary model; obtaining a local adjacent NGram model by using the confusion set of Chinese homonyms and a probability estimation algorithm; by using a weighted combination method and by calculating a sentence context support degree of a word in a sentence and a sentence context support degree of a homonym in a homonym confusion set corresponding to the word, determining whether a homonym error exists; marking the homonym error and providing a correction suggestion list, so as to implement Chinese homonym auto-proofreading. The Chinese homonym error auto-proofreading method provided by the present invention is quick in system response and high in efficiency and accuracy, and meets precision requirements of actual applications.

Description

technical field [0001] The invention relates to natural language processing in the field of artificial intelligence computers, in particular to the field of automatic proofreading of Chinese texts. Background technique [0002] With the rapid development of information processing technology and the Internet, traditional text work is almost completely replaced by computers. Electronic texts such as e-books, e-newspapers, e-mails, and office documents, blogs, and microblogs have all become part of people's daily lives. However, there are more and more errors in the text, which brings great challenges to the proofreading work. Traditional manual proofreading has low efficiency, high intensity, and long cycle obviously cannot meet the needs of text proofreading. [0003] Automatic text proofreading is one of the main applications of natural language processing, and it is also a difficult problem in natural language understanding. Chinese is entered into the computer through th...
