In the last part of this article,whether control strategy of information dissemination based on community in this article could control information efficiently in dissemination of the social network had been detected by simulation experiment.With the improved social network SEIR information diffusion model referred before,the experiment simulated social network information diffusion environment to develop and evolve autonomously test nodes in this diffusion environment according to diffusion rules and analyze the running outcome.Another group of experiment,which is added control strategy of information dissemination based on community on the foundation of this group of experiment,is outcome of simulation running after analysis
and injection of control strategy.By contrast results among 2 groups of environments,it's available to come to a conclusion whether control strategy of information had effectiveness mentioned in this article.
After injection of information control mechanism,the amount of spreading nodes has been controlled efficiently.But there's a period of time before dissemination has been significantly controlled from the beginning of running control mechanism,spreading nodes would be increased in a slowing rates relatively during this period.Meanwhile,the later control mechanism is injected,the faster rate is increased during this period.The main reason of this is that the a certain amount of spreading nodes had been accumulated before the running of control mechanism,the more spreading nodes is accumulated,the slower rate is controlled.

Finally, simulation experiments in this paper put forward based on the detection of the community information dissemination control strategy is effective control of information in the propagation of the social network. The paper before use improved social network information transmission SEIR simulation model, social network information communication environment, the test node in the spread of such environment according to spread freedom to development evolution rules, and analyzes the operation results. Another set of experiments in this group is based on experiment based on the information dissemination to community control strategy, analysis to join control strategy of the simulation results after operation. From the two groups of experimental comparison of can be obtained in this paper is effective information control strategy is the conclusion.
Join the information after control mechanism, the spread of the number of node information be effectively controlled. But, from the first operation control mechanism to spread obviously still need to control a period of time, this time spread in a node will also relatively slow speed increase. And, control mechanism to join the night, this paragraph of the growth of the faster. Analyzes the main cause is the control mechanism has already accumulated before a certain number of transmission node, the spread of accumulation of node, the more control of the slow speed appears.

Finally, through simulation testing in this article, community-based information dissemination control strategy can effectively control the spread of information in social networks. Experiment before the text to improve the social network the SEIR information dissemination model, the dissemination of information of the analog social networking environment, the test node in such a communication environment according to the propagation rules independent evolution, and analysis of operating results. Another set of experiments is to join in this group of experiments on the basis of the control strategy, community-based information dissemination and analysis of the control strategy simulation run results. The proposed control strategy is the validity of conclusions can be drawn from the comparison of results of two experiments.
The information control mechanism, the number of nodes of the dissemination of information has been effectively controlled. However, from the beginning of the operation control mechanism to spread significantly control still take some time, this time spread of nodes but also at a relatively slow speed increased. Moreover, the control mechanism is added later, this period of faster growth. Analysis of the main reasons is the control mechanism to run has already accumulated a certain number of communication nodes, these communication nodes accumulated more control the speed of the slower.
