Global Diffusion of the Internet VIII: Maximum Resolution Dichotomy for Global Diffusion of the Internet

The Global Diffusion of the Internet (GDI) framework was used to study the progress in the adoption of the Internet in close to 30 countries since 1997. A new methodology in data mining is presented to extend the use of Kiviat diagrams to visualize the framework cast in a supply-demand dichotomy. A maximum resolution topology is derived as an additional tool for exploratory data analysis of such GDI dichotomies

Maximum resolution topology for multi-attribute dichotomies

The Star Plot approach to high-dimensional data visualization is applied to multi-attribute dichotomies. It is observed that the areas of the plot for the two parts of a dichotomy may be used as an aggregate measure of their relative dominance. An optimization model is developed to determine a topology (or weighted configuration of the attributes) that maximizes the resolution of this measure with respect to a given set of reference dichotomies. © 2005 Institute of Mathematics and Informatics, Vilnius.link_to_OA_fulltex
