Abstract

The invention provides a view extraction method and device. The method comprises the steps of obtaining to-be-processed text content; inputting each statement in the text content into a preset subjective sentence recognition model to obtain a subjective sentence in each statement; wherein the subjective sentences are sentences for commenting the comment object; aiming at the subjective sentence, extracting a view quintuple in the subjective sentence; wherein the view quintuple comprises a comment object, a comment attribute, a comment word, a reviewer and comment time; according to the view quintuple, determining the proportion of each type of comments for the comment object and the comment attribute; determining the proportions of various types of comments for the comment objects and thecomment attributes and the subjective sentences as the views corresponding to the text content, so that the subjective sentences in the text content can be extracted firstly, then quintuple extractionand viewpoint analysis operations are carried out on the subjective sentences, the number of quintuples needing to be analyzed is reduced, the accuracy of quintuple analysis is improved, and the requirements for real-time performance and accuracy can be met.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a viewpoint extraction method and device. Background technique [0002] The current opinion extraction method mainly includes: extracting information such as the comment object and the emotion of the comment object from each sentence of the news article, and analyzing and determining the opinion in the news article according to the information such as the emotion of the comment object. However, in the above method, each sentence in the news article needs to be extracted, which greatly increases the amount of extracted information and greatly increases the analysis time of the extracted information, and it is difficult to analyze and obtain accurate opinions, thereby reducing the It is difficult to meet the requirements of real-time and accuracy. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related a...
