Problems solved by technology

However, when the user enters wrong words, mainly including: homophones, near-syllables, shape-synonyms, pinyin, multi-word omissions, etc., the above search engines or intelligent question answering systems may not be able to correctly or effectively handle such words. Words that prevent users from getting the information they need
For example, the original word is: Get chestnuts in the fire. For "Huozongquli" with homonyms, near-syllables, and pinyin errors, or "Huozhongqu" with homonyms, multi-word omissions, etc., the above search engines or None of the intelligent question answering systems can handle it correctly

no. 1 example

[0087] In the first embodiment of the present invention, an input error correction method, such as figure 1 shown, including the following specific steps:

[0088] In step S101, it is judged whether the input character string is full pinyin; if yes, execute step S102; otherwise, execute step S103.

[0089] Step S102, perform pinyin error correction processing on the full pinyin of the word string, and reverse check the corrected full pinyin into Chinese characters to obtain the first error correction result, and the process ends.

[0090] Step S103, perform word segmentation processing on the word character string, when the number of word segmentation in the result of word segmentation processing is greater than 1, execute step S104; if the number of word segmentation in the result of word segmentation processing is 1, the word character input by the user string as the second error correction result, and the process ends.

[0091] Step S104, converting the character string i...

[0096] In the second embodiment of the present invention, an input error correction method, such as figure 2 shown, including the following specific steps:

[0097] Step S201, pre-establishing a word list, a pinyin reverse look-up table and a word frequency table.

[0098] Specifically, step S201 includes:

[0099] Provide training corpus;

[0100] Segment the training corpus to obtain a list of words;

[0101] On the basis of the word list, the pinyin reverse look-up table is generated by using the pinyin reverse look-up table generation tool, and the word frequency table is obtained according to the word list by means of statistics.

[0102] In the embodiment of the present invention, in the process of establishing the word list, pinyin reverse look-up table and word frequency table, the word information provided by the training corpus is fully and effectively used, and can be quickly applied to self-defined word error correction in different fields.

[0128] Specifically, step S201 includes:

[0129] Provide training corpus;

[0130] Segment the training corpus to obtain a list of words;

[0131] On the basis of the word list, the pinyin reverse look-up table is generated by using the pinyin reverse look-up table generation tool, and the word frequency table is obtained according to the word list by means of statistics.

Abstract

The invention provides an input error correction method and apparatus. The method comprises the steps of judging whether an input word character string is full pinyin or not; if yes, performing pinyin error correction processing on the full pinyin of the word character string, performing a reverse query on the full pinyin subjected to the error correction to obtain Chinese characters, and obtaining a first error correction result; or otherwise, performing word segmentation processing on the word character string, converting the word character string into the full pinyin, performing the pinyin error correction processing on the full pinyin obtained by conversion, performing a reverse query on the full pinyin subjected to the error correction to obtain the Chinese characters, and obtaining a second error correction result. According to the method and the apparatus, a similarity calculation method is skillfully applied to similarity calculation of pinyin characters and similarity calculation of Chinese characters; and by applying the method and the apparatus to Chinese search engines and intelligent question-answer systems, the accuracy of query and question-answer of information input for words in the Chinese search engines and the intelligent question-answer systems can be remarkably improved.

Description

technical field [0001] The invention relates to the technical fields of natural speech processing and machine learning, in particular to an input error correction method and device. Background technique [0002] At present, users often conduct information inquiries through Chinese search engines or intelligent question answering systems, and a large part of the inquiries are input in the form of words. Both the Chinese search engine represented by Baidu and the intelligent question-answering system represented by Xiaoi robot can respond and give feedback to the Chinese words entered by users. However, when the user enters wrong words, mainly including: homophones, near-syllables, shape-synonyms, pinyin, multi-word omissions, etc., the above search engines or intelligent question answering systems may not be able to correctly or effectively handle such words. Words that prevent users from obtaining the information they need. For example, the original word is: Get chestnuts ...
