Study for Dynamic Computational Method of User Reliability in Open Knowledge Organization

For the existing problem of user reliability computing in open knowledge organization, the current related researches are analyzed, and then this paper puts forward a dynamic computational method of user reliability based on multi-attribute evaluation. The method introduces direct reliability, bonus-penalty factor, group consumption factor and user consumption factor to compute the user reliability. Followed by stochastic simulation experiments after all, compared to the existing models, this method is able to control the low quality behavior of users, and fully and dynamically reflect the influence of the behavior of the user and the group on user reliability. In addition, it gives a better picture of user reliability from multiple perspectives.
