Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present specification in combination with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only some of the embodiments of the present specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0030] In the above related technologies, error correction can be performed based on the BERT (BidirectionalEncoder Representations from Transformer) model. But on the one hand, in the BERT model, the characters in the error-correcting sentence are often masked in a random way, so that the BERT model does not have enough ability to detect whether each character in the error-correcting sentence has an error (only About 15% of wrong characters are dete...

Abstract

The embodiment of the invention discloses an error correction method and device and computing equipment. The method comprises the steps: according to pinyin features of characters in a to-be-corrected statement, detecting the first probability of each character in the to-be-corrected statement, the first probability being used for representing the possibility that the character is an error character; determining a first feature of each character in the statement to be corrected according to the first probability; according to the font characteristics of the characters in the to-be-corrected statement, detecting a second probability of each character in the to-be-corrected statement, the second probability being used for representing the possibility that the character is an error character; determining a second feature of each character in the statement to be corrected according to the second probability; fusing the first feature and the second feature to obtain a fused feature of each character in the statement to be corrected; and determining an error correction result of the to-be-corrected statement according to the fusion feature. According to the embodiment of the invention, the error correction effect can be improved.

Description

technical field [0001] The embodiments of this specification relate to the technical field of computers, and in particular, to an error correction method, device, and computing equipment. Background technique [0002] In recent years, with the introduction of deep learning, text recognition technology (such as OCR, Optical Character Recognition, optical character recognition) has made remarkable achievements and has been widely used. However, due to various factors, errors usually occur in the text recognition results. It is necessary to correct the sentences in the recognition results. [0003] In the related technology, an error correction algorithm can be used to correct the sentence in the recognition result. The error correction algorithm may include an error correction algorithm based on typo dictionary, an error correction algorithm based on edit distance matching and a model based error correction algorithm. [0004] The error correction effects of the above error...
