Geotagging the blogosphere
If you were to identify and pinpoint blog posts’ location data (i.e. mentioned locations in blog posts), a process known as geotagging or geocoding, these visualizations are the result. In the first and fourth picture, the color represents the popularity of a location (red is highest frequency). In the second and third picture, the size of the square represents the popularity of a location.
The original data set consisted of about 800 randomly chosen blogs with around 80.000 posts. Geotagging was done with ClearForest, Google Maps and World Gazetteer.
The meaning of these location data is — unfortunately — relatively arbitrary.
