Jisun An, Ingmar Weber
2015 arXiv   pre-print
Given the ever increasing amount of publicly available social media data, there is growing interest in using online data to study and quantify phenomena in the offline "real" world.  ...  The term "social sensing" is often used in this context to describe the idea that users act as "sensors", publicly reporting their health status or job losses.  ...  In our study, we limited ourselves to inferring state-level locations and used the user-provided location fields in combination with a dictionary previously used in [11] .  ...
