geographies of time, weekends
While municipal boundaries (zip codes or administrative boundaries) are actually necessary to provide order and organization to the city, they are not reflecting how people actually live and perceive areas.â€¨The specific goal here is to build novel maps of city areas' boundaries, mapping the different patterns of use (activities on Social Media) on specific areas of the city, and aiming to derive and represent new boundaries of the city neighborhoods: evolving, interplaying and overlapping.
By measuring social media activities (e.g. profile of people sharing from a place, characteristics of venues of the place, "pulsation" of social media activities
according to diverse timestamps in the place, typology of pictures people take in different areas, etc etc) in specific places of the city we aim at identifying some initial clustering operations highlighting similarities and drawing novel boundaries of those area sharing a strong "identity".
This experiment will build novel geographies out of Social Media data production, rather than confirming / evaluating existent and well known ones. Goegraphies of time is the first of a series of spatial aggregation based on Social media. Areas are defined and coloured according to the time period of the day they are pulsing the most.
The areas are characterised by more fragmentation than in the days of the week. The places and times of contributions are more closely linked to domestic life and a multi-directional mobility, related to different free-time preferences.
There are, however, some overall observations:
The central area, specifically the area of San Babila and Duomo, the axes from Via Dante and Via Torino, as well as the gardens of Porta Venezia and Parco Sempione have a very high concentration in the afternoon hours (midday to 6pm).
The popularity of the southern area of the city (Navigli, Porta Ticinese and Porta Romana) in the evening (from 6pm until midnight) is confirmed.
University campuses (Politecnico Leonardo, Politecnico Bovisa, Bicocca) are thin on contributions compared to lessons times during the week.
