Problems solved by technology
[0005] The present invention provides a method, device, equipment and medium for discriminating similar characters, which are used to solve the situation that the current discrimination method is prone to similar stroke codes, but the actual Chinese characters are not similar characters at all, which leads to the accuracy of discriminating similar characters lower question

The invention provides a method, a device, equipment and a medium for distinguishing characters with similar shapes. The method comprises the following steps: acquiring a stroke code of a target Chinese character, a preset stroke endpoint coordinate of the target Chinese character, a stroke code of a to-be-distinguished Chinese character and a preset stroke endpoint coordinate of the to-be-distinguished Chinese character; determining the similarity between the stroke code of the target Chinese character and the stroke code of the Chinese character to be discriminated; according to the preset stroke endpoint coordinates of the target Chinese character and the preset stroke endpoint coordinates of the to-be-discriminated Chinese character, determining a structural difference degree between the target Chinese character and the to-be-discriminated Chinese character; and according to the similarity, a first preset threshold value matched with the similarity, the structural difference degree and a second preset threshold value matched with the structural difference degree, judging whether the Chinese character to be judged is the similar-shape Chinese character of the target Chinese character or not. According to the method for discriminating the characters with the similar shapes, whether the target Chinese characters and the Chinese characters to be discriminated are the characters with the similar shapes or not is comprehensively judged by combining the two indexes of the similarity and the structural difference degree, and the accuracy of discriminating the characters with the similar shapes is improved.
Description
technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a method, device, equipment and medium for discriminating similar characters. Background technique [0002] With the continuous development of computer technology, Chinese character encoding is becoming more and more mature. By encoding the strokes and sequences of Chinese characters, different Chinese characters can be generated. For example, the stroke code of "country" is 25112141, each number of the code represents a different stroke, and the arrangement between the numbers represents the order of the strokes. [0003] Relying on the development of Chinese character encoding, Chinese character sentence recognition technology has become an important aspect of natural language processing. When recognizing Chinese character sentences, it is necessary to perform word splitting and semantic recognition. If the user enters wrong Chinese characters due t...
