The Research Of Information Dissemination On Micro-blog

With the Internet’s entry into the Web2.0era, the interaction between peoplebecomes more and more closely. Besides, the dissemination of information becomesmore and more convenient. Currently, the growth of Facebook, twitter, Sinamicro-blog and other social media is explosive. It does not only have far-reachinginfluence to the traditional forms of media, but also bright more academic problems. Itcreates a new field and puts forward new requirements for scientific and technicalworkers.We use Sina micro-blog as source of experimental data and study the analysistechnique for information dissemination related to the social computing in the newform and new background.First, the paper introduces the research background. The network has entered theinformationalized and social age. A large number of grassroots people have createdricher media content which has extended this massive network information even more.Facing the new situation, we urgently need new technology and method to solvepractical problems.Then it introduces the method about data acquisition from Sina micro-blog. Wecan get the data through the Sina’s API or create webpage reptile as we do in Web1.0times. The webpage reptile is "vertical" crawler, which takes up according to specificareas. There is introduction about accomplishment for log-in simulation andinformation extraction.After that, the paper focuses on the analysis for the spread of information in Sinamicro-blog. In Sina micro-blog, the information is spread based on a tree structure.This paper presents two algorithms to generate the tree-like structure. Using these twoalgorithms, I get lots of information dissemination trees and use them to do statisticanalysis job.Finally, this paper introduces the public opinion monitoring system based on theabove technology. In this system, we use rich visualization technology to show thedata, and successfully combine the theory and practice.At the end, this paper gives some current problems and some prospects for thenext stage of development.
