User Knowledge Exchange Network And Emotional Research In Academic Virtual Community

The continuous development of Internet technology has brought unprecedented changes to human life.Social,travel,life or learning exchange,people are increasingly using the Internet.The academic virtual community established by the Internet provides a diverse,open,and effective platform for people to exchange knowledge,and more researchers to use academic virtual communities for academic exchanges.That makes up for the lack of academic exchanges in the real world.On the one hand,the reputation of researchers can be improved in both the real world and the academic virtual community.Measuring and analyzing of academic virtual communities can help us to grasp the online academic exchanges and provide reference for the development of the disciplines;help the academic virtual community to improve the academic exchange atmosphere,the communication mechanism,the academic staff to academics and the usage rate of the virtual community.The academic virtual community provides a platform for researchers to communicate online.Users have complex communication networks,and network structures and features have an important impact on knowledge exchange.First of all,the paper understands the basic situation of the academic virtual community,combs the relevant literatures at home and abroad,the theories and methods related to this paper.Secondly,this paper gives the basic definition of knowledge exchange network,builds an abstract network,takes the muchong academic virtual community as an example,generates user knowledge exchange network with actual data,and observes the topology structure and network characteristics of the network.It is found that the network has the characteristics of a small world,the overall density of the network is low,and the connections between users are not tight.Then,this paper defines the user node and the emotional node,establishes a connection between the user's emotion and the user's communication network,and generates a user relationship——emotional tendency network with actual data.It is often found that the status and role of emotionally rich users in the community is more important.The emotional orientation is closely related to the user's role.The role of negative emotions and neutral emotions in the network cannot be ignored.Finally,based on the research results,relevant suggestions are put forward to provide theoretical support for the improvement of knowledge exchange efficiency in academic virtual communities.
