Embodiment 1

[0046] An embodiment of the present invention provides a method for identifying grammatical errors in Chinese, which identifies grammatical errors in Chinese speech. Through this method, the accuracy of identifying Chinese grammatical errors can be improved. Specifically, figure 1 The flow chart of the steps of the recognition method for Chinese grammatical errors provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method for identifying Chinese grammatical errors provided by this embodiment includes the following steps S101 to S106.

[0047] Step S101: Obtain speech words to be recognized.

[0048] Wherein, the method for identifying Chinese grammatical errors can be performed on a single speech, or on a text including multiple speeches such as an article or a paragraph of text. When identifying a single speech, the single speech is the speech to be identified. When recognizing the text, the words can be separated first, and then each separated...

Embodiment 2

[0085] Embodiment 2 of the present invention provides a preferred method for identifying Chinese grammatical errors. Part of the features and corresponding technical effects are the same as those in Embodiment 1 above. Reference may be made to Embodiment 1 above, and details will not be repeated here. In this embodiment, the M model groups corresponding to the one-to-one correspondence between the bidirectional cyclic neural network and the LR classifier are preset, that is, a plurality of model groups are trained. Each model group can obtain a recognition index of a speech to be recognized, that is, each speech to be recognized can obtain M recognition indexes, where M is a natural number greater than 1. specifically, figure 2 The flow chart of the steps of the recognition method for Chinese grammatical errors provided by Embodiment 2 of the present invention, such as figure 2 As shown, the method for identifying Chinese grammatical errors provided by this embodiment inclu...

Embodiment 3

[0099] Embodiment 3 of the present invention provides a preferred method for identifying Chinese grammatical errors. Part of the features and corresponding technical effects are the same as those in Embodiment 1 above. Reference may be made to Embodiment 1 above, and details will not be repeated here. This embodiment is aimed at the recognition of the text to be recognized including multiple speeches. In this embodiment, M model groups corresponding to one-to-one correspondence between the bidirectional cyclic neural network and the LR classifier are preset, that is, multiple models are trained. The structure of each model group is the same, the initial training parameters are randomly generated, and the corresponding wrong speech group of the text to be recognized can be obtained through each model group, that is, the text to be recognized corresponds to M wrong speech groups, where , M is a natural number greater than 1. specifically, image 3 The flow chart of the steps of...

Abstract

The invention provides a Chinese grammatical error recognition method, device, computer equipment and computer storage medium. The method includes obtaining speech to be recognized; calculating an initial feature group corresponding to each character in the speech to be recognized; inputting the initial feature group into a bidirectional cyclic neural network to obtain intermediate features; Splicing the order of each word in the speech to obtain the result feature; input the result feature to the LR classifier to obtain the recognition index of the speech to be recognized, wherein the recognition index is used to represent the probability of the speech to be recognized including grammatical errors; and According to the recognition index, it is determined whether the words to be recognized include grammatical errors. Through the present invention, the recognition accuracy rate of Chinese grammatical errors can be improved.

Description

technical field [0001] The invention relates to the technical field of grammatical error recognition, in particular to a Chinese grammatical error recognition method, device, computer equipment and storage medium. Background technique [0002] Chinese is an ancient and complex language. During its long history of development, it has developed many characteristics that are different from other languages. For example, compared to English, Chinese has neither singular nor plural forms, nor changes in verb tense. Relatively speaking, Chinese has more ways of expressing, its grammatical structure is more flexible, and it tends to use short sentences instead of clauses. Moreover, Chinese likes repetitive expressions, while English omits more. These large differences distinguish Chinese grammatical error recognition from other languages. [0003] As more and more people learn Chinese, there is an increasing demand for automatic recognition of Chinese grammatical errors, such as a...
