Assuming their potential impacts on human verbalization behaviors, one possibility is to link the functions of places to verbal representations [...]

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 [...]
