Making Sense of Cities Using Social Media: Requirements for Hyper-Local Data Aggregation Tools

摘要

As more people tweet, check-in and share pictures and videos of their daily experiences in the city, new opportunities arise to understand urban activity. When aggregated, these data can uncover invaluable local insights for local stakeholders such as journalists, first responders and city officials. To better understand the needs and requirements for this kind of aggregation tools, we perform an exploratory study that includes interviews with 12 domain experts that utilize local information on a daily basis. Our results shed light on current practices, existing tools and unfulfilled needs of these professionals. We use these findings to discuss the requirements for hyper-local social media data aggregation tools for the study of cities on a large scale. We outline a list of key features that can better serve the discovery of patterns and insights about both real-time activity and historical perspectives of local communities.
