Acquiring method and system for propagation indexes of internet public opinion events

Abstract

The invention provides an acquiring method for propagation indexes of internet public opinion events. The acquiring method comprises steps as follows: 1, inputting the public opinion events; 2, collecting related public opinion articles grabbing the public opinion events from each medium source and storing the public opinion articles in a public opinion event analysis library; 3, analyzing all the public opinion articles about the public opinion events, sorting all medium-sourced articles in the order of publishing time of the articles to form a public opinion event propagation track, and meanwhile, performing single-article propagation index calculation on each article; 4, extracting public opinion event propagation track key information by the aid of the article propagation indexes; 5, constructing a final model by use of the public opinion event propagation track key information. With the adoption of the method, a more precise model is adopted, and the development trend of the public opinion events in the whole life cycle from generation, development, outburst, peak, weakening to end can be better reflected.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and system for acquiring the spread index of Internet public opinion events.

AI Technical Summary

Problems solved by technology

[0011] To sum up, there are corresponding schemes for the calculation of the public opinion transmission index, but the existing schemes have problems such as relatively simple module construction, failure to solve the complex situation of cross-media source communication, and insufficient media sources.

At the same time, it should be noted that public opinion communication is a dynamic event, and the establishment of its model should be able to reflect the life cycle of public opinion events such as formation, development, outbreak, peak, and decline. Influencing factors of media source dissemination, and in the existing schemes, none of the above requirements can be met
