The Research And Implementation Of Microblogging Initiator Detection And Dissemination Analysis

In Microblogging Information Propagation territory, Initiator Detection ofMicroblogging and dissemination Analysis is one of the most important part,which alsoprovide an important basis for Microblogging Information Filter. Propagation trendanalysis and Microblogging public opinion monitor.So based on the feature of Largevolumes of data, complex network of information Propagation and information repairsimply, we devise the calculation methods of Initiator Detection of Microblogging anddissemination,and realize it in the system.First, through the research of information propagation model and discussion ofmicroblogging transmission mode, this paper do relevant studies on MicrobloggingInformation Propagation. Second, through the analysis of the existing text similaritycalculation method, a calculation method of paragraph similarity is devised on the basisof Sentence matching and string similarity calculation method, with the aim ofcalculating Microblogging text, which is characterized by its shortness and thesimpleness of content modification.Third, based on Microblogging text similarity,time and the information propagationrelationship of users, an information propagation probability calculation method isdevised to infer information propagation probability of nodes that don’t have significantinformation propagation relation so as to build information propagation path. Fourth, anew Event Initiator Detection technique is introduced, on the basis of the linkingrelation between Microblogging and its content as well as publishing time.Finally, this paper focuses on the calculation methods of Microblogginginformation dissemination. At the same time, the estimation methods of Microblogginginformation dissemination are also devised on the basis of the large spending of spacetime in dissemination calculation. we change the union calculation to intersectioncalculation,and make the calculation easier.In addition, some Microblogging data is selected in this paper to experimentallytest the calculation methods of devised Microblogging text similarity, initiator detection,and the estimation methods of dissemination. Meanwhile, Microblogging initiatordetection and dissemination analysis is also constructed to guarantee the systematicaloperation of all the functional modules in YHPODS system.
