Center node: "evaluating and optimising models of network growth"
  Abstract: This paper presents a statistically sound method for measuring#R##N#the accuracy with which a probabilistic model reflects#R##N#the growth of a network, and a method for optimising parameters#R##N#in such a model. The technique is data-driven, and#R##N#can be used for the modeling and simulation of any kind of#R##N#evolving network.#R##N#The overall framework, a Framework for Evolving Topology#R##N#Analysis (FETA), is tested on data sets collected from#R##N#the Internet AS-level topology, social networking websites#R##N#and a co-authorship network. Statisticalmodels of the growth#R##N#of these networks are produced and tested using a likelihoodbased#R##N#method. The models are then used to generate artificial#R##N#topologies with the same statistical properties as the#R##N#originals. This work can be used to predict future growth#R##N#patterns for a known network, or to generate artificial models#R##N#of graph topology evolution for simulation purposes. Particular#R##N#application examples include strategic network planning,#R##N#user profiling in social networks or infrastructure deployment#R##N#in managed overlay-based services.
