Problems solved by technology

However, this approach has many limitations
First of all, there are limitations in the definition of edges. The existence of an edge can only be determined when there is a concern relationship between users, or there is a corresponding interaction between users. Therefore, this method cannot predict the influence of all users. ;Secondly, although there are a large number of edges in the social netw

Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and implementation examples.

[0049] Such as figure 1 As shown, the establishment method of influence propagation model based on opinion vectorization includes the following steps:

[0050] Step A: Crawl relevant information of users' blog posts in social networks, and establish a communication network based on opinion influence;

[0051] For example, for the Weibo social network platform, use the scrapy module to create a crawler to crawl data on Weibo, including the user's original blog posts, reposted blog posts, follow relationships, and corresponding operation time. Afterwards, according to the forwarding relationship of users, a corresponding viewpoint influence dissemination network is established. Specifically, it includes the following steps:

[0052] A1: According to the user relationship, establish a network structure graph G=(V, E) between users, where V...

Abstract

The invention discloses an establishment method of an influence propagation model based on viewpoint vectorization. An existing method has limitation, a model cannot effectively calculate the influence among users, and a certain effect can only be achieved in a single social network or group environment generally. The method comprises the following steps: crawling related information of original content of a user in a social network, and establishing a propagation network based on viewpoint influence; searching a local influence user set consistent with the user viewpoint in the influence propagation network by utilizing random walk; searching a global influence user set similar to the user viewpoints in the influence propagation network according to the viewpoint similarity; searching a user set opposite to the user viewpoint in the influence propagation network; and finally, establishing an influence propagation model based on viewpoints. According to the method, the influence user set opposite to the user viewpoint is considered, and the influence propagation model based on the viewpoint can be more accurately reflected.

Description

technical field [0001] The invention belongs to the technical field of the Internet, in particular to the technical field of social network analysis, and specifically relates to a method for establishing an influence propagation model based on viewpoint vectorization. Background technique [0002] Social network influence is a manifestation of an individual's influence on the behavior of other users by publishing or reposting opinion content on the Internet platform, specifically manifested in likes, reposts, etc. In recent years, with the rapid development and popularization of computer technology, more and more users express their opinions and spread content on social networking platforms such as Twitter (Twitter) and Weibo, and influence other users. Around the aspect of social influence between users, researchers have carried out a lot of work and realized a variety of applications, including marketing, advertising and public opinion control and many other fields. [00...
