A Comprehensive Evaluation Model Of Social Network Knowledge Dissemination Effect

In the 21st century,human society entered the era of knowledge economy.The effect of knowledge dissemination in social networks reflects the degree of development of social groups to a certain extent.At present,the research on social network knowledge dissemination mainly starts from two aspects:the efficiency of knowledge transfer and the scope of knowledge dissemination.However,it is not comprehensive to evaluate the effect of knowledge transfer from social networks simply from the perspective of transfer efficiency or scope of dissemination.To this end,it is necessary to consider these two aspects to evaluate the effect of knowledge dissemination in social networks.In social networks,knowledge is transferred through people's communication.However,whether knowledge transfer and knowledge transfer efficiency can be related not only to people's own factors,but also to whether other individuals in the social network participate in dissemination activities.Similarly,whether people transmit knowledge is not only affected by external factors,but also closely related to the individual's own knowledge level.Based on this,this paper first establishes the knowledge transfer model,and proposes a dissemination scope model.Finally,a comprehensive evaluation model of dissemination effect is established,which can evaluate the knowledge dissemination effect in the network from two aspects:knowledge transfer efficiency and dissemination scope.Finally,the paper analyzes the consistency with the real propagation situation through simulation experiments,and compares with the existing research results to verify the rationality and effectiveness of the model.
