Kolloquium Geoinformatik Big spatiotemporal data analysis based on social sensing

With the rapid development of information and communications technology (ICT), ubiquitous social sensing data bring new opportunities for us to understand our socioeconomic environments. We use the term social sensing to represent the study of characteristics of human spatio-temporal behavior, and the discovery of socio-economic environments, by various means of social sensing. This talk introduces the concept of social sensing and social sensing techniques, and discusses data, the associated analysis methods, and applications. Social sensing has brought us massive amounts of spatial data related to humans. The spatio-temporal analysis of social sensing data is working for different aspects of humans' lives, such as environment, emergency, economy, and urban planning. In the coming big data era, GIScientists should investigate theories in using social sensing data, and develop new methodologies to understand human activity based on social sensing.
