This experiment aims at unveiling the perception of safety in different zones of the city, as well as specific public spaces.
The analysis has been carried through a selection of the geo-tagged contributions (twitter + facebook + flickr + foursquare) that indicates the sentiment of fear (semantical sentiment analysis and relevant hashtags), and the plotting on the map of a 1 month-long extraction of data. Results were then split by gender / time of the day / days of the week in order to find further meaningful insights.
A second analysis has been carried using absolute (non geo-referenced) contribution localized on the map if a recognizable toponym was included in the body of the shared message.
