The Power Nodes Set Influence Analysis On Network Information Spreading

The continuous development and improvement of Internet technology has brought about tremendous changes in people?s lifestyles.The society has become increasingly networked.People?s lifestyles have gradually shifted from traditional offline activities to online activities,especially the emergence of social networking platforms.It has an important influence on social communication patterns and information dissemination patterns.The spread of network information is faster,wider,and more influential.It has an important impact on the public opinion environment,and it plays a key role in the dissemination of information on the Internet.It is an influential node with a large number of fans.Therefore,The research of influence nodes has also become a hot issue in the research of complex networks.In many researches,most of the research perspectives are mostly ind ividual,while neglecting the impact of the structure between the influence node sets on information dissemination.Based on this,the main research object of this paper is the influence node sets,the content is the influence analysis of power node sets on network information spreading.The core parts of this paper mainly include chapters 3,4 and 5.The third chapter is to study the impact of the Weibo big “V” set on information dissemination through the e xample of the “girls attacked in the Beijing Heyi hotel” in April 2016.The study finds that the big "V" group has an important influence on information dissemination,and this raises the core issue of this paper,namely the influence of influence node sets on information dissemination.The fourth chapter mainly includes the definition of the power node set and the identification of the power node set recognition algorithm.The correctness of the algorithm is verified through experiments.The fifth chapter uses Matlab software to study the influence of t he information structure on the network structure of the power node set under the uncertainty of the information source.This paper studies the influence of the collection of power nodes on the information dissemination from the perspective of collections.At the same time,it considers the information sources in the process of information dissemination as indefinite.Through research,it is found that the network structure of the power nodes set has important influence on information dissemination.The results mainly include the following aspects:(1)The scope of information dissemination will increase with the increase of the power aggregation coefficient;(2)The more the network density of power nodes set is,the greater the scope of information dissemination;(3)When the information source is a power node,the number of information sources has little effect on the effect of information dissemination.These conclusions of this paper have important practical significance,which can play a guiding role in the control of information dissemination,can effectively control the cost of information transmission,and can also use the power node set to effectively monitor and filter information.
