A method for identifying key blog sets in blog information dissemination

Abstract

The invention discloses a method for quickly and accurately identifying key blog collections in blog information dissemination, the steps of which are: 1) collecting and determining the attention relationship and link relationship between blogs in units of blogs; 2) taking blogs as a unit Nodes build a blog network graph, and the edges of the graph are the associations between blogs; 3) Determine the weight of associations (directed edges) between blogs according to the information dissemination model; 4) Calculate the influence of each blog on other blogs based on the blog network graph Expected value; 5) Identify the set of key nodes with the greatest influence on information dissemination in the blog network graph. The invention combines the information dissemination model, applies the relationship between blogs, and quickly identifies key blog collections in blog information dissemination by calculating information dissemination expectations, so as to facilitate the supervision of blog information.

Description

technical field [0001] The present invention relates to the problem of fast identification of key blog node sets in the dissemination of blog information, especially for the increasing popularity of blog sites (especially microblogs) in the Internet age, which have become one of the mainstream platforms for information dissemination such as news and comments, and require effective supervision To help identify and control information on the Internet. Background technique [0002] Blog (Weblog or blog) is an information sharing platform with the Internet as the carrier and managed by individuals. A blog is a collection of web pages containing text, links, images, etc., and is managed by the blogger (ie, a user registered on the blog site), who posts new articles (Posts) from time to time for people to browse or repost. With the emergence of a large number of blog sites (such as the well-known foreign Twitter, domestic Sina Weibo, etc.), blogs have become one of the mainstream...

Problems solved by technology

The advantage of the simulation method is that it can be applied to different information dissemination models, and the accuracy of key node sets identified is high; the disadvantage is that the execution performance is too low, and it is suitable for relatively static information dissemination networks

The blog information dissemination network has a large amount of information, rapid updates, and various forms of information dissemination. The existing methods cannot meet the key node set identification requirements of blog information dissemination.
