Modeling dynamics of information networks.
We propose an information-based model for network dynamics in which imperfect information leads to networks where the different vertices have widely different numbers of edges to other vertices, and where the topology has hierarchical features. The possibility to observe scale-free networks is linked to a minimally connected system where hubs remain dynamic.
متن کاملModeling the Dynamics of an Information System
The article concentrates on the nature of a social subsystem of an information system. It analyzes the nature of information processes of collectivity within an IS and introduces a model of IS dynamics. The model is based on the assumption that a social subsystem of an information system works as a nonlinear dynamic system. The model of IS dynamics is verified on the indexes of the stock market...
متن کاملModeling the Dynamics of Social Networks
Modeling human dynamics responsible for the formation and evolution of the so-called social networks – structures comprised of individuals or organizations and indicating connectivities existing in a community – is a topic recently attracting a significant research interest. It has been claimed that these dynamics are scale-free in many practically important cases, such as impersonal and person...
متن کاملModeling the Structural Dynamics of Industrial Networks
Economic institutions involved in creating and delivering products and services to end-users operate within networks of relations that " organize " the flows of activities. Historically, an implicit assumption underlying research into these networks is that the patterns of relations are controlled by the organizations involved-the so-called top down view. More recently, we have come to recogniz...
متن کاملStructure and Dynamics of Information in Networks
Preface The present notes are derived from a course taught at the University of Southern California. The focus of the course is on the mathematical and algorithmic theory underpinning the connections between networks and information. These connections take two predominant forms: • Network structure itself encodes a lot of information. For instance, friendships between individuals let us draw in...
