| Popis: | Visually conveying time-dependent changes in tag maps is insufficiently addressed by current approaches. Typically, for each time range a tag map is determined, and the change between tag maps of subsequent time ranges is progressively visualized. Our method compares tag maps locally in order to enable a continuous display of geographical topic changes among subsequent time ranges. We further provide an alternate tag map variant focusing on frequency changes instead of relative frequency values to visualize the geospatial-temporal rise and fall of topics. |
