Abstract

The present application relates to the field of artificial intelligence. A high-utility item set containing a plurality of strong associated words is obtained by performing item set mining on a text to be classified, and classification prediction can be performed according to a word vector matrix of the high-utility item set, thereby improving the accuracy of text classification. The invention particularly relates to a text classification method and device, computer equipment and a medium, and the text classification method comprises the steps: obtaining a to-be-classified text, carrying out the item set mining of the to-be-classified text, and obtaining a high-efficiency item set corresponding to the to-be-classified text, wherein the high-efficiency item set comprises at least two word groups; vectorizing each word group in the efficient item set to obtain a word vector matrix corresponding to the to-be-classified text; and inputting the word vector matrix into a text classificationmodel for classification prediction to obtain a text category corresponding to the to-be-classified text. In addition, the invention also relates to a blockchain technology, and the to-be-classified text can be stored in the blockchain.

Description

technical field [0001] The present application relates to the field of artificial intelligence, in particular to a text classification method, device, computer equipment and media. Background technique [0002] With the rapid development of the Internet and the advent of the era of big data, text classification has become a hot research issue in the field of natural language processing. [0003] Existing text classification methods generally use deep learning algorithms to predict text categories. The deep learning algorithm is very dependent on the selected text features in the process of predicting the text category. By converting the text into a word vector, the word vector is used to determine the distance relationship between each text feature. However, deep learning algorithms cannot eliminate the interference of synonyms on text classification, which reduces the accuracy of text classification. [0004] Therefore, how to improve the accuracy of text classification h...
