Visual Analysis Method Of Network Communication

The birth of the Internet has brought ecedented impact to and make enormous changs tothe way of information dissemination. When the Internet as a new carrier of communicationin our life, it will carry the interpersonal communication function.The virtual world on theInternet has created various applications, especially micro-blog is able to be fully utilized.Now micro-blog becomes an important platform to disseminate information and diffuseopinion by the the vast number of users and convenient and rapid way to disseminateinformation and the transmission way of information distribution. Users can through the“follow” and “followee” to form a large online community transmission network, which hasproduced many influential users at the same time.It will be a great significance to study information dissemination process and influentialnodes in micro-blogs. In addition to study effects of propagation process to understand nodesin the process of communication, by virtue of which factors can become a powerfulcommunication node, which is of great vital to the effective management of public opinion.There are still some disadvantages in recent studies:1) Evaluation model of the influenceare based on the PageRank algorithm, the evaluation index is simple, not comprehensive;2)the influence did not introduce to topology structure into the network;3) While visual thepropagation path of micro-blog, the layout of the node takes up a lot of space, cause a lot ofspace waste;4) the current research on user influence only stay on the overall assessment ofthe user’s influence, and has no further study.In view of the above problems, this paper carrying out research on informationdissemination and influence based on network analysis and information visualization. Themain achievement are as follows:1) construct a set of evaluation index system, and proposesa model to evaluate the influence based on factor analysis method;2) introduce influence inthe topological structure of the network transmission, and propose a large-scale nodehierarchical layout algorithm;3) based on the plane polar coordinates method, propose animproved radius tree layout algorithm;4) introduce matrix scatter diagram to explorecorrelation between influence evaluation index, the line graph exploration types of “opinionleaders”;5) take the data of Jiang men Branch of China Mobile to experiment, results showthat: The proposed method has good visibility, the research results has a certain referencevalue to Micro-blogging Marketing and public opinion guidance.
