Abstract: In order to analyze the role of opinion leaders in microblog online social network dissemination and the life cycle of microblog information dissemination,an OLL graded opinion leader model was proposed.Firstly,the microblog data are crawled,and statistical analysis is carried out.Secondly,the dissemination power is constructed as a function related to three factors such as the number of forwarding,the degree of activity and the number of fans,and then a weight calculation method based on hierarchy analysis is established.Finally,the computed dissemination power and OLL mo-del are used to analyze the dissemination function of opinion leader and the life cycle of microblog.The simulation results show that the dissemination effect of opinion leader in themicroblog information dissemination is very strong.The error is caleculated between the OLL model and threereal data sets of errors are 9.6%,13.4% and 4.5% respectively.It is proved that the proposed OLL model is reasonable and effective for analyzing the life cycle of opinion leader in microblog information dissemination.

Key words: Communication power, Microblog communication, Microblogging life cycle, Opinion leader
