Embodiment Construction

[0048] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0049] refer to figure 1, a method for calculating and sorting the popularity of news subjects in one embodiment of the present invention, comprising the following steps:

[0050] S1, calculate the basic news popularity ratio: obtain the subject set E, and calculate the basic news popularity ratio R of any subject c in the current calculation period t ct , where c∈E.

[0051] In this step, by using the basic news popularity ratio as the basic data calculation, the impact of the small number of news on non-trading days on the calculation can be reduced.

[0052] In one embodiment, this step uses the following calculation formula to calculate the basic news popularity ratio R of subject c ct :

[0053]

[0054] Among them, C ct is the number of...

Abstract

The invention belongs to the technical field of data processing, and particularly relates to a news subject popularity calculation and sorting method and device, equipment and a storage medium. The method comprises the following steps: acquiring a main body set E, and calculating a basic news popularity ratio of any main body c in a current calculation period t; calculating a historical average news popularity ratio of each subject; after the subjects with the basic news popularity ratio larger than the historical average news popularity ratio are sorted in a preset sorting mode, taking the first N subjects; calculating basic transaction values for the first N main bodies respectively, and obtaining the transaction values after normalization processing is carried out on the basic transaction values; and performing descending sorting according to the transaction values, and outputting a sorting result. According to the method, the popularity and the popularity change rate of the subjects are considered, the subjects with high news popularity are prevented from being ranked in the front all the time, and the subjects with large news popularity change rate and extremely low news popularity value are also prevented from being ranked in the front.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method, device, equipment and storage medium for calculating and sorting the popularity of news subjects. Background technique [0002] With the development of the Internet, the amount of news produced every day is increasing, and the analysis of news and the application of the analysis results are becoming more and more important. An important application of news analysis in the field of finance and economics is to extract companies, industries and other subjects from the news, and sort and display the subjects, so that users can intuitively see which subjects are highlighted on the day. [0003] The Chinese patent "CN104731857 A Quick Calculation Method for Public Opinion Heat" provides a method for calculating the heat of public opinion, which calculates the heat of information in Weibo, search engines, news and forums, and then adds several heat to get ...
