Microblog information dissemination key node recognition method based on improved PageRank algorithm

Abstract

The invention provides a microblog information dissemination key node recognition method based on an improved PageRank algorithm. The method comprises the steps that 1, information is acquired; 2, text information with the most forwarding number in a microblog group is determined; 3, text information using @ user identifier is acquired by means of the text information acquired in the step 2, wherein the user is B; 4, high frequency words are calculated by means of the text information acquired in the step 3; 5, the microblog text information of the user B is acquired and then compared with thehigh frequency words, whether or not the text information with the most forwarding number of members in the microblog group A is forwarded by the user B is determined, if it is determined that the text information is forwarded by the user B, whether or not B transmits the text information to a user C is determined, and then a dissemination path of the information is formed; 6, the microblog groups to which the users on the dissemination path belong are determined, and then a microblog group concern network is constructed; and 7, the most powerful microblog group is determined by means of theWeiboRank algorithm. According to the method, mining of key nodes among the microblog groups and in the groups is achieved, a complex data model does not need to be built, group discovery is conveniently and quickly achieved, and the high stability is achieved.

Description

technical field [0001] The invention relates to the field of data analysis, in particular to a method for identifying key nodes of microblog information dissemination based on an improved PageRank algorithm. Background technique [0002] Weibo has become a landmark product of Times Network since its inception. This Internet application with a strong "self-media" attribute has become an important social media due to its immediacy and convenience. However, credibility is the weak point of "self-media". Some key users engage in topic manipulation in the process of information dissemination, so vulgar content, rumors, false information, etc. are prone to appear, and the credibility of Weibo information has become a big problem. Internet information disseminates extremely fast, and the content of microblog public opinion information will pose a threat to social and public safety. [0003] Research on microblog network information data analysis and mining influential nodes in inf...
