Geovisualization of knowledge diffusion a case study in data minin

The diffusion of knowledge and technology is a complex spatial process. Using geovisualization technology to visualize and analyze diffusion and dissemination of knowledge from the spatial view is of great value. Selecting the field of data mining as research subjects, we bring forward a new way to visualize knowledge diffusion of SCI papers based on the combination of scientometrics and geovisualization technology. Through converting relevant factors of knowledge diffusion into feature layers, we can use all kinds of thematic maps to visualize the factors and process of knowledge diffusion. Based on it, we find some interesting result of knowledge diffusion in this field. It shows the method is helpful to discover the law of knowledge diffusion and will lay the foundation for further studying of data mining.
