| Abstract:In this paper, we combined temporal analysis and spatial analysis together,
and proposed the Electron Cloud Model (ECM) which is based on the Schrodinger equation
and Niels Bohr atomic theory. The ECM is used to conduct temporal visual analysis of
micro-blog sentiments. In the ECM, we made an attempt to mapping a score of sentiment
to the electron stability and took neutral sentiments into consideration. We applied kernel
density estimation and edge bundling to conduct space-varying visual analysis of sentiment.
Kernel density estimation visualized sentiment changes in different levels of detail naturally
while edge bundling was used to reduce visual clutter of edge crossing and reveal high-level
edge patterns. Finally, we implemented an analysis system, conducted three case studies
and made simple comparisons with other visualize methods. |
