Credibility model of microblog user information based on hierarchical analysis
Zhang Ta · Journal of Beijing Information Science & Technology University · 2015
To solve the problem of micro blog users' credibility,through preprocessing of source linguistic data,the user data in standard format are gained. A user authority model is established to build a index system based on the hierarchy analysis by extracting four indicators from the users information including integrity,activity,communication scope and communication strength. Then,by applying the analytic hierarchy process( AHP) structure model,the value of the weight coefficient of the index is determined,and the authority value of each micro-blog user is calculated. Finally,the user information credibility model is constructed. The experiment shows that the model has good accuracy in evaluating the credibility of micro blog users.
