Knowledge dissemination refers to the process of social activities in which a certain social member uses a specific media to spread specific knowledge information to another part of the society in order to obtain a certain dissemination effect.The development of the Internet and the improvement of computer technology provide multiple channels of communication for knowledge dissemination,knowledge has the characteristics of multi-channel dissemination in the network environment.The traditional single network is no longer suitable for the simulation knowledge dissemination environment,only when the knowledge is transmitted to a more complex network sturcture for research is more in line with the actual situation.Furthermore,the multi-channel dissemination characteristics of knowledge greatly increase the difficulty of research on the benefits of knowledge dissemination,so it is necessary to find a way to integrate the multi-channel dissemination environment of knowledge to simplify its research.On the basis of combing the theory of complex networks,this paper firstly extends the knowledge dissemination environment to the dual network by analyzing the characteristics of knowledge dissemination in a single network.Considering that the same user is affected by different degrees of dissemination in different network layers,divide the impact of users into positive and negative impacts,and according to the number of positive impacts on users,the user's activation conditions are divided into"or"conditions and "and" conditions.Then,from the three dimensions of network structure,interpersonal relationship and individual cognition,the traditional linear threshold model(LTM)is extended to OR-LTM and AND-LTM models.Secondly,the knowledge dissemination tree is introduced according to the living-edge model(LEM)and the reachability concept in a single network.According to the number of finite branches in the knowledge dissemination tree,the conditions for satisfying the reachability of users are also correspondingly divided into"or" conditions and "and" conditions.Then,under these two different conditions,the live-edge model in a single network is extended to two models,OR-LEM and AND-LEM,and it is proved that OR-LEM and AND-LEM are equivalent to OR-LTM and AND-LTM,respectively.Then,an approximate method for quickly calculating the user knowledge dissemination benefit in the dual network and an example analysis are given under the two extended live-edge models.In order to better reflect the ubiquitous dissemination characteristics of knowledge,the knowledge dissemination environment is extended to the general interactive network,and two methods for integrating multi-channel dissemination paths and their improvements are given under the new dissemination environment.The method enables the issues related to the benefits of knowledge dissemination in the context of ubiquitous knowledge dissemination can be translated into a single network for discussion.
