Seven Years of Social Sensors

The aim of this paper is to review seven years of research on a specific vision of social media which is that of social sensors, i.e., alternative information systems able to detect and characterize interesting and yet unreported information and events in real-time, crossing topics, locations and language barriers. In particular, we here present a computational exercise based on a Topic Modeling technique over a set of papers citing probably the first contribution about the conceptualization and formalization of the social sensor keyword. By extracting topics from 367 (English) titles and correlating them with metadata such as the year of publication and the number of received citations, we tried to light up interesting aspects and research directions in the social media mining community.
