Based On The Microbloinublic Oinion Events Node Geographic Spread

From the Angle of geography, the spread of information refers to information ina certain period of time from one location to other location on the transfer process.This study based on April10,2013"The ancient city of phoenix charge event"happened to analyze the spread of public opinion in microblog, mainly from the eventdiffusion mechanism, diffusion path, geographical characteristics and diffusion modeland so on four aspects to discuss the microblogging public opinion events ingeographical spatial diffusion phenomenon.The study found that:(1) Public opinionevents as a whole takes the form by the core to the edge of the level of diffusion.Public opinion events in microblog diffusion: abide by the nodes in the model, theright to have a center node, namely information publisher for the first time, then thenode is connected to the bridge, and at last the long tail node, the spread of publicopinion events in microblog influence degree depends on bridge node size.(2) Publicopinion events in present stage diffusion time and present characteristic s-shapedcurve. Event in the ancient city of phoenix charging time can be divided intopreclinical stage, evolution period, outbreak, spread and fading period five stages ofdiffusion. In addition, in the ancient city of phoenix in the diffusion process of chargeaccident, proliferators showed increased form a certain cumulative number, roughlythe present s-shaped diffusion, accords with the general law of diffusion ofinnovation.(3) Public opinion events, there exist some differences in geographicalspatial diffusion. On the one hand, the different period of geographical spatialdiffusion has certain differences, mainly spread in the geographic space time sectionand time curve is consistent. On the other hand, is a different type of geographicalspread exist differences between microblog users. Certification microblog users, thisblogger weibo influence are very big, depth and breadth of information diffusion isthe biggest of all. Its appeal is not enough strong blogger, there is no way to get thestrength proliferators help fan base, depth and breadth of information diffusion arelow.(4) The proximity effect on the spread of public opinion space dimensions. Theancient city of phoenix for events in the process of spatial diffusion presents a certain degree of proximity effect. Many microblog users of the ancient city of phoenixcharge event information forwarding, is under the influence of adjacent area or closefriends and forwarding. Events in the ancient city of phoenix charges, however,further studies have found that information in the process of geographical spatialdiffusion, the effect of adjacent to "homogeneous" surrounding the scope is limited tothe region.(5) From coastal to inland presents on the process of space characteristicof the diffusion. From the space pattern of the overall point of view, microblog usersinfluence the size and the density of urban distribution from the east coast to theinterior west will decrease trend. In addition, the development of informationizationcaused huge gap between urban and rural areas, make ordinary farmers unable to cityresidents have network information platform, at the same time, more can’t the firsttime come into contact with the microblog information diffusion.This thesis from the following five aspects:The first part of introduction mainly introduces the research background of thisthesis and first related research progress in recent years. Secondly elaborated thisthesis research object and research method, research significance of the thesis againgiven certain self assessment, have certain innovation, finally determines theconception and framework of this study.The second part introduces the "microblog" and "public opinion" and themeaning of "public opinion", is the main feature of node in microblog diffusion areexpounded and the related progress in recent years, finally analyzes the geographicaldiffusion of innovation theory and applications of geographical diffusion ofinnovation theory in geography.The main content of the third part is combined with related cases to analyze themicroblogging public opinion events node diffusion mechanism and diffusion path,microblogging public opinion events in the spread of microblog is through thegovernment, the audience under the function, the traditional media and opinionleaders. By applying statistical analysis software SPSS, the public opinion in sinamicroblog integral calculation and analysis of the phenomenon of diffusion, events are analyzed in detail the spread of the spread of the internal mechanism and underthe background of different paths.The fourth part is mainly based on the actual case by using Photoshop andARCGIS software for data processing and analysis, discusses the charge eventmicroblogging public opinion in the ancient city of phoenix nodes spread diffusioncharacteristics of space and time characteristics, node diffusion model and so on threeaspects of content. First is the time of public opinion events diffusion characteristics,through public opinion events in time to a detailed analysis on the diffusion of spacecurve, is in line with the diffusion of innovation curve characteristics; Secondly frommacro and micro two aspects analyzes the node geographical spread characteristics ofpublic opinion events; Finally, according to the characters of the spread of the wholepublic opinion events, gives several cases of diffusion path diagram in detail, throughsum up five microblogging public opinion is also given node pattern.The fifth part is the conclusion of this study. Based on node geographical spreadof microblogging public opinion event study summarized and concluded, is given inthe specific research scope of the relevant conclusions, the study is discussed in theend still exist deficiencies.
