Abstract

The invention discloses an automatic tagging method and apparatus, a computer device and a storage medium. The method comprises the steps of performing word segmentation preprocessing on a to-be-tagged text to obtain a preprocessed text; inputting the preprocessed text to a TF-IDF algorithm model to obtain a keyword set of the to-be-tagged text; according to the keyword set of the to-be-tagged text, obtaining an initialized transfer matrix, performing multi-time iterative multiplication operation on the initialized transfer matrix and initial keyword probability distribution until convergenceto obtain final keyword probability distribution; and obtaining a corresponding row of a maximum probability value in the final keyword probability distribution, obtaining a keyword corresponding to the corresponding row of the maximum probability value, and setting the keyword as a tag of the to-be-tagged text. According to the method, an article is tagged by automatic learning, so that manual tagging is avoided, the tagging efficiency is improved, and the manpower cost is reduced.

Description

technical field [0001] The present application relates to the technical field of article classification, in particular to an automatic labeling method, device, computer equipment and storage medium. Background technique [0002] Article tags are helpful for searching and categorizing articles. At present, manual tagging is commonly used, that is, authors edit tags for their own articles, but not all authors tag their own articles. If a large number of untagged articles are added by manual marking, the efficiency is extremely low, and the labor cost is greatly increased. Contents of the invention [0003] This application provides a method, device, computer equipment and storage medium for automatic labeling, aiming to solve the problem of adding labels to a large number of unlabeled articles in the prior art through manual labeling, resulting in extremely low efficiency , and greatly increased the problem of labor costs. [0004] In a first aspect, the present applicatio...
