Title:
METHOD AND DEVICE FOR EXTRACTING TEXT KEYWORDS
Document Type and Number:
WIPO Patent Application WO/2021/169347
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of artificial intelligence, provides a method and device for extracting text keywords. The method comprises: obtaining a target text to be subjected to keyword extraction; classifying the target text by using a convolutional neural network model to obtain a classification result, the convolutional neural network model being used for classifying the target text; on the basis of the classification result, extracting the top N words that have the greatest influence on the classification result, and using the top N words as keywords of the target text, the target text comprising several words, and the N being an integer greater than zero. According to the present application, keywords that are strongly related to text classification can be extracted, and the influence of text length on keyword extraction is reduced, so that the accuracy of keyword extraction results is improved.
