Abstract

The invention provides a text label generating method and device. Regarding targeted text, keyword extraction is conducted by the adoption of strategies corresponding to all label types, so that candidate labels of the label types are subjected to cross validation among the different label types after the candidate labels of all the label types of the targeted text are obtained, and finally, according to the validated candidate labels, a targeted label of the targeted text is determined. Because label extraction and cross validation are conducted separately regarding the different label types which include entity words, fragment text and / or topics, the accuracy of the label extraction is improved, and the technical problem is solved that the accuracy of the label extraction in the prior art is not high.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a text label generation method and device. Background technique [0002] For the label extraction of various texts such as papers and news, it specifically refers to extracting multiple labels from the text that can reflect the content of the text and the interests of readers. The tags extracted here can be used as more refined words or fragments than abstracts, which help readers quickly understand the content of the full text. It plays an important role in text classification, recommendation and association. [0003] However, in the prior art, tags are only extracted based on word frequency, etc., and the accuracy of the extracted tags is not high. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] For this reason, the first purpose of the pre...
