Abstract

The application discloses an article classification method and device, computer equipment and a storage medium. The method includes: inputting a word-document matrix, which corresponds to to-be-labeled articles, into a pre-built LDA (Latent Dirichlet Allocation) model to carry out training to obtain a corresponding topic-word matrix and a document-topic matrix; acquiring a topic, which correspondsto each document in the to-be-labeled articles, through the document-topic matrix, and correspondingly adding a topic label for each document to obtain already labeled articles; and classifying the already labeled articles according to the topic labels to obtain article classification results. According to the method, article word segmentation is carried out, then the topic to which each articlebelongs can be obtained simply by acquiring the document-topic matrix, the topics are utilized to classify the articles, automatic learning is adopted to replace manual classification, manpower costsare saved, and classification efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of article classification, in particular to an article classification method, device, computer equipment and storage medium. Background technique [0002] Article tags are helpful for searching and categorizing articles. At present, the commonly used method is manual tagging, that is, authors tag their own articles, but not all authors tag their own articles. If a large number of untagged articles are manually marked and then classified after adding tags, instead of being classified after no tags or intelligently added tags, the efficiency will be extremely low, and the manpower will be greatly increased. cost. Contents of the invention [0003] This application provides an article classification method, device, computer equipment, and storage medium, aiming to solve the problem that a large number of untagged articles in the prior art are manually marked and then classified after adding tags, r...
