Abstract

This solution involves artificial intelligence and provides a feature representation method for the topic, including: obtaining multiple knowledge points in the topic, and forming a knowledge map through the relationship between the knowledge points: using a custom thesaurus to clean the text content, so that The text content only retains the words in the custom thesaurus; each word in the text content is converted into a word vector through the word vector algorithm; the formula is converted into a character vector through the character vector algorithm; through convolution-deconvolution The self-encoder converts the image into a pixel matrix; combines the entity vector, word vector, character vector, and pixel matrix of the knowledge map to form a topic information matrix. The feature data of the questions extracted by the present invention include all information such as text, formulas, images, characters, etc., and can improve the accuracy of math topic recommendation and math topic classification.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, and in particular, to a method, device and storage medium for characterizing a topic. Background technique [0002] At present, most of the topic feature extraction only extracts the text content in the topic, but does not extract the relationship between knowledge points, the content in the image, and the content in the formula. In mathematics, there are usually a large number of knowledge points, and the semantic relationship between the knowledge points can effectively expand the feature representation of the topic. However, this semantic relationship is difficult to be discovered by traditional methods (topic model, word vector). SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a method for representing the characteristics of a topic, which is applied to an electronic device, including: [0004] Obtain multiple ...
