For the problem of fake users,behavioral characteristics of Sina micro-blog users were analyzed,and then feature variables for distinguishing the category of users were extracted according to online time,posting time,interaction degree and so on.Applying logistic regression algorithm,a user reliability evaluation model was put forward.The experimental result shows that the proposed model not only can recognise the traditional fake users zombie fans,but also has high recognition rate for new fake users.Sina micro-blog users can be roughly classified according to the confidence.The proposed model is stronger on practicability.
