Research On Information Diffusion Based On Network Dimension-force

Today cyberspace and realistic space both exist in our life, especially the development of Internet has provided a function prepared platform about open information diffusion and resource sharing to information diffusion. The superiority dimension-forces which network has not only promoted the information communication of cyberspace, but also put the realistic space's information diffusion mapping to cyberspace through information coupling, on the basic of information communication in cyberspace, considered that the behavior of demand acceptance about information destination in realistic space, weighs diffusion whether to occur. We call the coupling spaces information space.In information space, the network dimension-forces make information diffusion in realistic space have essential transformation through information coupling, in fact, it is that information diffusion in realistic space is no longer restricted by geography, capacity and time. Under the impetus of network dimension-forces, the information of source can reach any destinations in broad spatial scope fast and synchronously, and can accumulate information instantaneously to surmount the threshold value of information destination, then can realize the diffusion distance to be willfully far, the quantity of information destination are willfully more, the diffusion effect obviously strengthens. The research on information diffusion in information space is proposed based on above questions. By consulting lots of domestic and foreign related literatures and intelligence information, and on the foundation of related research results, the paper takes diffusion system - diffusion dynamic & resistance - diffusion mechanism - diffusion model - countermeasure measures as a master line, has an exploring research to information diffusion questions in information space. The main research content is as follows: First, due to not have seen the same reports about main subject research in domestic or foreign periodicals, therefore, the paper utilizes the induction analytic method and the comparison analytic method, collects and consults lots of related literatures and intelligence information in domestic and foreign, carries on the reorganization and induction to it, summarizes and refines the logical master line and related research methods of this paper.Second, the paper introduces the basic theory namely the network dimension-force theory, and defines some concepts which are information diffusion, information space, information diffusion in information spaces and so on, which establish the foundation for the later research from concepts and ideas.Third, the paper limits the connotation of information diffusion system on the basis of the general system theory, analyses the constitution of information diffusion system from the complicate system view and carries on the elaboration to its characteristics. Based on this, this paper analyses and elaborates systematically the forming conditions of information diffusion.Fourth, on the basis of information diffusion system, this paper divides the dynamic& resistance of information diffusion into the endogenous powers, the exogenous powers and the resistances. And the endogenous powers include information original driving force, source supply propelling force, information destination demand traction force and information potential propelling force; the exogenous powers include the intercommunication force, the clustering force and the synchronization force; the resistances include node spacing friction force, cultural difference inertia force and the resistance of information asymmetry. Then using the information theory, the cybernetics and the system theory, the paper carries on the comprehensive and systematical elaboration and analysis to the action forces among the essentials of information diffusion system, constructs the dynamic & resistance mechanism model of information diffusion. In this foundation, the paper carries on the annotation to the connection mechanism of the endogenous powers, the exogenous powers and the resistances, and carries on the further discussion to the forming and development of information diffusion.Fifth, on the basis of the diffusion dynamic & resistance and the goal, this paper carries on the annotation to the forming mechanism of information diffusion. On the foundation of limiting the connotation of information diffusion mechanism, the paper expatiates and analyses the constitution of diffusion mechanism. Then using the core thought of the network dimension-force theory, this paper carries on the dissertation to the source information network communication mechanism. Using the multi-stages choice time gamble theory, the paper carries on the annotation to the microscopic acceptance mechanism that information destination accepts source information according to the realistic environment. And using the logical language, the paper carries on elaboration to the feedback mechanism. At the same time, borrowing the concept "field", the paper proposes, establishes and analyses the information diffusion field, and analyses information diffusion's mechanism using the field theory in physics, then reveals the intrinsic essence and rules of information diffusion from field angle.Sixth, on the basis of information diffusion mechanism, the paper researches on the model of information diffusion. On the foundation of elaborating the connotation of information diffusion model, this paper constructs the ladders lattice model of information diffusion process, and analyzes its characteristics. At the same time, based on the source information's diffusion process in the diffusion space is a Markov process which has navigate, the paper uses Markov navigation chain principle to establish the information space-time diffusion model, describes the diffusion space-time's expansion model and characteristics, and uses computer to simulate the model validity.Finally, the paper proposes the countermeasures and measures which can promote information diffusion from the following three aspects: they are advancing the informationization construction, constituting the policy that promotes information diffusion and establishing the humanistic environment which is advantageous to information diffusion.
