Problems solved by technology

The traditional news value evaluation method is more about the importance evaluation of universality, and the evaluation of news sources and users on social media is indiscriminate, not only cannot be directly used for the prediction and evaluation of the importance of news texts in a single field At the same time, it also seriously restricts the effective dissemination of data and policy information in various industries

Abstract

The invention relates to a text-based news importance evaluation method and apparatus, and an electronic device. The method comprises the steps of reading text news; preprocessing the text news to obtain original data; extracting characteristic values of the original data, wherein the characteristic values comprise metadata, keywords and probability model characteristic values; obtaining the scoreof each characteristic value according to the weight ratio corresponding to each characteristic value; the device comprises a text news reading module, a text news preprocessing module, a feature value extraction module, a feature value weight determination module and a text news importance evaluation module. The electronic device comprises a memory and a processor, a computer program capable ofrunning on the processor is stored in the memory, and the text-based news importance evaluation method is realized when the processor executes the computer program. According to the invention, the news importance evaluation efficiency and precision are greatly improved, and the real-time dynamic evaluation of the text news is realized.

Description

technical field [0001] The invention relates to the technical field of news value evaluation, in particular to a text-based news importance evaluation method, device and electronic equipment. Background technique [0002] With the development of network technology and the wide application of new media, the number of various types of news produced and released has greatly increased. How to "dig for gold in the sand" and choose news with higher value is particularly important. [0003] The existing news value evaluation technology pays more attention to the general news, and calculates the impact of different news value feature items on the predicted news value according to the change of user attention, so as to complete the calculation of important news value feature items. The traditional news value evaluation method is more about the importance evaluation of universality, and the evaluation of news sources and users on social media is indiscriminate, not only cannot be dire...
