open questions, so far:(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: 1. Can we use social media to understand how neighborhoods are perceived? 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?
