Embodiment Construction

[0039] ,See Figure 4 , the present invention is based on a probabilistic graph model microblog water army recognition method, the specific steps of the method are as follows:

[0040] Step 1: In the Sina Weibo platform, suppose there are 4 users whose attribute feature vectors are:

[0041] cu 1 =(0.4,1.4,3.0,5.6),cu 2 =(0.6,2.0,5.4,3.1),cu 3 =(0.8,5.2,15.4,16.3),cu 4 =(1,4.3,17.3,12.3)

[0042] The corresponding behavioral characteristics are:

[0043] you 1 ={0.1,0.3,0.5,0.4}, yu 2 ={0.3,0.6,0.4,0.4}, yu 3 ={0.7,0.4,0.9,0.6}, yu 4 ={0.8,0.9,0.8,0.8}

[0044] Then the learning samples formed are:

Abstract

The invention discloses a microblog water army identifying method based on a probabilistic graphical model. The microblog water arm identifying method comprises three steps as follows: quantizing user attributes and conventional microblog using behaviors into characteristic indexes which are respectively attribute characteristics and behavior characteristics of the user; regarding probability that the user belongs to the water army as a hidden variable of a graph by constructing a probability graph structure between the attribute characteristics and the behavior characteristics; and predicating the probability that other users belong to the water army by utilizing parameters of a sample learning graph model as well as the learned probability graph model. The invention provides the microblog water arm identifying method which is automatic, effective and quick by searching how to automatically identity water army users in the microblog platform, so that the identification is effectively carried out under a large data volume condition of the microblog. Moreover, the microblog water army identifying method has a good practical value and an extensive application prospect in the technical field of data mining.

Description

technical field [0001] The invention relates to a microblog troll identification method based on a probability graph model, which is applied to WEB data mining, public opinion monitoring, rumor detection, troll identification, etc., and belongs to the technical field of data mining. Background technique [0002] Weibo has become the most influential social media by virtue of its fast spreading speed, large number of users, and convenience. At present, more than half of Chinese netizens use Weibo, and China has become the largest country in the world in terms of Weibo users. With the rapid increase in the number of users of the microblog platform and the continuous expansion of the communication effect, microblog is also becoming the main battlefield of the "network water army", which is called the Weibo water army (hereinafter referred to as the water army). [0003] The water army uses the microblog media to create public topics, distort public opinion on the Internet, and...
