The geographic map shows the locations of documents based on analyzing their textual content (a process typically referred to as “geo-tagging”). The Active Document is highlighted by a yellow asterisk, and the letters [a-e] represent the five highest-ranking documents in the Similar Topics view. If users have an interest in a specific location rather than a topic, they can click anywhere on the map to activate the closest document (hovering above the map previews the document, but does not activate it).

After entering a search term, the set of results is visualized in the geographic map. Circular markers show the target geography of the found articles. The diameter of the marker represents the number of matches for a given location, its color the average sentiment of these matches. Using a color range from yellow to either green or red, trajectories link the source and target geography of an article (source geography = location of the publisher; target geography = main location referenced in the document). The little ‘+’ symbol on the right side of the window allows users choosing alternative base maps (e.g. NASA Blue Marble, Political Borders, Google Terrain, etc.), as well as deactivating the circular markers or trajectories.
