VISUALIZING LOCATION-BASED DATASETS USING "TAG MAPS"

The visualization of datasets by associating text (keywords) with location and optionally with time is provided. This visualization may help the user better understand and analyze the contents of the dataset. The visualization takes as input a keyword and related parameters such as location, importance/relevance factors, time, visualization level, and keyword category, and displays the selected keywords on a map, at their associated location, with the size or other characteristic of the keyword varying according to its relevance.
