Towards using Volunteered Geographic Information to monitor post-disaster recovery in tourist destinations
The aftereffects of disaster events are significant in tourist destinations where they do not only lead to destruction and casualties, but also long-lasting economic harms. The public perception causes tourists to refrain from visiting these areas and recovery of the tourist industry, a major economic sector, to become challenging. To improve this situation, current information…

How good can predictions from check-ins be?
Check-in data such as provided by Foursquare is one kind of social media feeds which gained considerable interest over recent years. This interest is partly due to their high degree of semantic detail, given that users check-in at places which are categorized by a relatively well-defined taxonomy. One associated prevalent task, in research as well…

Mining and correlating traffic events from human sensor observations with official transport data using self-organizing-maps
Cities are complex systems, where related Human activities are increasingly difficult to explore within. In order to understand urban processes and to gain deeper knowledge about cities, the potential of location-based social networks like Twitter could be used a promising example to explore latent relationships of underlying mobility patterns. In a recently published paper (Steiger…

Social Media Data: Topological Outliers and Their Influence on Spatial Analysis
Social media data is one of the recent and prominent sources of georefrenced social information. It allows in-situ insights into the everyday lifes of ordinary people. For all that, social media data also confronts us with considerable analytical challenges. One of these challenges is the mingling of different user habits, functions of geographic space and,…
