Microblog Information Flow Diffusion Research Of The Characteristics Of Space And Time

In this paper, on the reference and the basis of summarizing the predecessors’research, from the perspective of geography information, by fractal theory and basedon the theory of the core-edge with sina weibo forward ACTS as information flowspace a new perspective of communication studies, select "420" ya ’an earthquakecases,Respectively for ordinary users of sina weibo and Authenticated user select theforwarding of two weibo for research, the application of SPSS and ARCGIS softwarefor data processing, and generate the space distribution, to analyze weibo flowdiffusion spatial distribution characteristics.Reference information diffusion intensityindex, the city’s first degree and rank-size rule from the perspective of time and spacefor the spread of the information flow characteristics are analyzed and discussed,found that:(1) in the weibo forward the quantity relationship with weibo release timehas the characteristics of the distribution of the "long tail". Ordinary users microblogand V weibo forward the most amount of focus on the first day of release weibo, fullyreflects the characteristics of weibo and timely update the characteristics of fast speed,weibo after release quickly by other users access to information, with the passage oftime gradually covered by the more new information and buried, the microblogging isgradually no longer aroused people’s concern.(2) Spread in the microblog informationflow, information flow diffusion capacity in cities across presents different leveldifference. Beijing show that the spread of absolute advantage, in all time of twoclasses of weibo is located in the flow of information diffusion strength first. Strong atthe same time, the information flow diffusion node city, Shanghai, chengdu,guangzhou, nanjing and so on also in two classes of weibo every time play animportant role in information diffusion.Diffusion level presents a "pyramid" type tothe number of cities, fewer city has contributed to a larger quantity of informationdiffusion, and the intensity of flow diffusion weaker lower level city, the proportionof the total number of cities is larger, but these cities for the spread of informationflow capacity is very small.(3) In the national scope, the diffusion of information flowin the present relatively scattered and balanced state, in the province as the research scale range, to form the "A large, multiple small" type and "two large, multiple small"type of provinces,the spread of the information flow more concentrated in the firstcity, information diffusion is focused on the first of a few provinces cities and twocities, showing a strong information central tendency. So in weibo informationdiffusion in the form of a wide range of dispersion, state and local concentration ofspace.(4)Weibo in the flow of information diffusion in line with the rank-sizedistribution characteristics, the average user users microblog weibo and V are presenta focus on information flow distribution, and the more dispersed and balanced state.Forward from the overall situation, the flow distribution of both types of present areasonable concentration, the characteristics of the wide spread of information. Asequence leading to Beijing, Shanghai, chengdu, guangzhou, nanjing and other cities,formed a strong information gathering node in the space, prominent contribution tothe spread of the information flow.This research will be divided into five parts:The first part of the introduction. First of all, this paper introduces the researchbackground; Then the microblogging, microblogging information dissemination andinformation flow space research at home and abroad is reviewed and analyzed; Afterhas expounded in this paper, the research purpose and meaning; Finally described inthis paper, the research train of thought.The second part is the research basis. In this part, introduced in this paper, thebasic theory and research method. Respectively the profile and application of fractaltheory and an overview of the core-edge theory and application are expounded, andanalysis; And elaborated this article research methods: literature analysis, casemethod and model analysis.The third part is the microblog information dissemination. This part of thisarticle research object-weibo are introduced and analyzed. Weibo is first proposed ininformation communication; And then the information transmission in weibocharacteristic and function are analyzed.The fourth part is the empirical research. This research data acquisition andprocessing instructions; And analysis the main content of this article, including the flow of information diffusion intensity of space characteristics, the first degree in theapplication of information diffusion and the rank-size rule in the application of theinformation diffusion.The fifth part is conclusion and discussion. The research conclusion of this paperand needs to improve and perfect aspects are summarized.
