Research On The Mode Of Knowledge Diffusion In Online Social Network

In recent years, along with Facebook, Renren, twitter, microblog, letters and other social networking platforms have emerged, online social worldwide craze set off a wave of heat. SinaWeibo, as China’s first micro-blogging service, to keep the knowledge of the social media platform from the initial transformation, and ultimately become a bearer of knowledge sharing and transfer process online social tools. As knowledge of information provided microblog has immediacy, openness, multi-media technology and fragmentation characteristics, coupled with the huge media influence and a strong social function, it is still among the mainstream microblogging forefront. SinaWeibo service advantages of knowledge has become increasingly prominent, prompting people will gather once again the focus of attention to the proliferation of social networks of knowledge and spread on top of the problem.Diffusion of Knowledge worked in the field of knowledge management, social networks, complex networks experienced a sustained and long research process. Nevertheless, the definition of knowledge diffusion has not been uniform in academia so far. Research methods and uses mostly stick to the existing literature overview of the theory, mathematical model derivation, social network analysis, empirical research is very scarce, so that the data can support the extreme lack of appropriate conclusions, and knowledge diffusion research of online social networks is unknown.The articles based on social network theory, research issues related to online social networks in knowledge diffusion model. Firstly, through literature study will collect and analyze literature data, the theoretical basis of social networks, research status, as well as content knowledge diffusion, models, patterns, effects and other elements were comprehensive and informative commentary. On this basis, summarizes existing research gaps, and to determine the theme of this paper and the specific content, namely "a pattern of four points." Secondly, the use of questionnaires and observation, from the knowledge diffusion network structure, diffusion processes, influencing factors, the diffusion effect four levels on SinaWeibo knowledge diffusion model in empirical research, statistical data analysis software will be a an order, and made a detailed analysis and discussion. Again, according to the results of the data analysis, combined with existing research findings, systematically expounded the theory of online social networks in knowledge diffusion model, and build an analysis framework of knowledge diffusion model. Finally, a summary of the full text, but also pointed out the lack of research exist in the process. Research results including:(1) Knowledge diffusion network structure:the relationship between the intensity and characteristics of nodes in the network.(2)Knowledge diffusion process:the content type is diffused and forms of knowledge, behavior and motivation main nodes, knowledge diffusion channel characteristics.(3)Factors affecting the diffusion of knowledge:Node factors, relationship factors, environmental factors.(4)The diffusion effect:the breadth of knowledge diffusion, diffusion depth, duration, frequency and knowledge of the case to release the key quality.(5)The general pattern of online social networks to spread knowledge and analytical framework.
