is it possible to build indicators of urban perception and health through social media contributions?

(1) topology

1. Can we use social media to understand contribution patterns based on location, time and topic?  Can we build a picture of overall emotional content and / or meaning from this information?

2.  Where to people contribute data from the most?  Where are they most likely to comment on topics of policy or broad social impact to the city?

3.  Can we “map” emotions?  Does the built environment impact these emotions and how?

4.  Are there communication “dead zones”?

5.  How does seasonality and commuter patterns or tourism impact the social information being reported?

open questions, so far:

(2) areas / neighborhoodidentity:

open questions, so far:

2.  How flexible / overlapping are neighborhood boundaries? 

3.  What typifies social media involvement at a neighborhood scale?  Why area certain neighborhoods similar or different in their useage patterns?

4.  How does seasonality influence these patterns?

Pleens

Pleens is a tool to discover stories, journeys and products told starting from the place you, or your friends, are in when you launch an app: what really matters is not geography or proximity but narration.

Geolocalized stories may include suggestions for tryouts and purchases, provided they are related to the narration and to the emotional context.
