Embodiment 1
[0029] Embodiment 1: as Figure 1-3 As shown, a similar Chinese character extraction method based on matrix operation, first extracts the Chinese character matrix and establishes a Chinese character matrix database, the user inputs a reference Chinese character, calculates the similarity between the reference Chinese character and each Chinese character in the database, and finally outputs a certain number of similar characters Chinese character. Among them, when calculating the similarity between Chinese characters, operations such as matrix translation, subtraction, and absolute value are used.
[0030] The specific steps are:
[0031] Step0: Extract the Chinese character matrix and establish a Chinese character matrix database; generate a Chinese character matrix I with a size of m×n according to the m×n pixel Chinese dot matrix font m×n , store all Chinese characters and the generated Chinese character matrix in the database, and form a Chinese character matrix database;...

The invention relates to a method for extracting similar Chinese characters based on matrix operation, belonging to the technical field of Chinese information processing. The invention firstly extracts a Chinese character matrix and establishes a Chinese character matrix database, the user inputs a reference Chinese character, calculates the similarity between the reference Chinese character and each Chinese character in the database, and finally outputs a certain number of similar Chinese characters. Among them, when calculating the similarity between Chinese characters, operations such as matrix translation, subtraction, and absolute value are used. Compared with the prior art, the present invention mainly solves the phenomena of manpower consumption, low accuracy and poor flexibility in extracting similar Chinese characters in the prior art, and increases the accuracy of extracting similar Chinese characters currently relying on computers.
Description
technical field [0001] The invention relates to a method for extracting similar Chinese characters based on matrix operation, belonging to the technical field of Chinese information processing. Background technique [0002] The extraction of similar Chinese characters is a basic research in the field of Chinese information processing, which is conducive to the development of Chinese teaching, typesetting, editing and other businesses. Especially for Chinese teaching, many similar Chinese characters are artificially listed in textbooks for students to learn and distinguish correctly when they first learn Chinese. If similar Chinese characters are only a few, it is not difficult to distinguish them manually, but the Chinese character culture is extensive and profound, and the quantity is huge, so the implementability is weaker if it is distinguished manually. [0003] At present, the similarity extraction of Chinese characters is mainly based on the similarity between Chinese...
