In the broad context of the social urban data mining applied in the study of the city, Instagram and its geotagged posts are used in this dissertation to understand urban dynamics, and to produce new visual representations and insights in relation to the city of Turin. The idea of “community” and “city” as they adapted to the Information age are introduced in the first chapter as premises to validate the decision of using geotagged Instagram posts as a source of potential knowledge in the field of urban studies. The “eloquence” of geotagged Instagram posts is found in its intrinsic characteristics of social media where users filter through the selection of pictures the reality around them, making them a powerful proxy to understand the contemporary city in its complexity.
