The Spreading Of Network Popular Words In Virtual Community

With the rapid development of computer technology, more than a quarter of people in the world have used internet, more and more Internet users participate in the spreading of information and knowledge. Then an important information and knowledge sources----the virtual community appeared. Virtual community provides a knowledge-sharing space to people with no time and geographical constraints. So people have not to share knowledge face to face or spend a lot of money to buy paper books. Knowledge spreading in virtual community is much different from in the reality world. In the virtual community, maybe hundreds or even thousands of times spreading can be finished just in a few days. This new form of knowledge and information dissemination have attracted the scholars and the scholars already have made a lot of research..The internet popular words represent a new knowledge and information of a virtual community, one popular word often on behalf of a news event or some network witticisms such as "buy sauce","Brother Sharp","sheep voice" and so on. Popular words are often easy to understand, close to the people's livelihood, and the feature of vivid makes it a rapid spread in a quite short time, such as in2009, the number of "Sheep voice"appeared in the virtual community was up to150,000. The spreading of popular words in virtual community have affected tens of thousands of Internet users, and it have brought a significant impact on our lives, economic, political, and media sector, so it caught the eye of the media.Most of the existing research on the virtual community knowledge and information spreading are from the perspective of qualitative and empirical research, quantitative analysis are very few, so we can not understand the virtual community knowledge and information spreading process in a more scientific and systematic way. In this paper, we take the spreading of the popular words in the virtual community for example, Study the spreading mechanisms combined with the complex systems theory from a quantitative and audio-visual point of view.The basis of population dynamics on the the view point spreading and spreading of infectious diseases is very similar, putting infectious disease model as the standard can estimate the population average parameters, such as interpersonal contact rates, immunization rates, and so on. These quantities are quite reasonable to clarify the spread of ideas, and it provides a simple method for the sociology quantitative method and the behavior patterns. Here we have created the virtual communities knowledge and information dissemination model which based on the SIR model, it describes the emergence and spreading process of the network popular words.In this paper, we found the virtual community knowledge and information dissemination layered model----the virtual community network popular words spreading model and the spreading model of popular words between the virtual community which takes the population movement into account; We also analysis the main factors that influence the spreading of popular words, the We have discussed the network structure's impact on the spreading of knowledge through compared the popular words spreading in virtual community with the common rumors spreading in reality; At last, according to the data of the empirical research, we analysis the different types of networks popular words'differences in the spreading process and further verify the model.This study provides a more scientific theory for researching on the virtual community knowledge and information dissemination, it also can enrich the theory of knowledge spreading and provide scientific decision-making both for controlling the spreading of malicious rumors and strengthening the knowledge and information spreading in the virtual community. This paper have great theoretical and practical significance.
