Abstract:

The remarkable success of online social media sites marks a shift in the way people connect and share information. Much of this information now contains some form of geographical content due to the proliferation of location-aware devices, thus fostering the emergence of geosocial media - a new type of user-generated geospatial information. Through geosocial media we are able, for the first time, to observe human activities in scales and resolutions that were so far unavailable. Furthermore, the wide spectrum of social media data and service types provides a multitude of perspectives on real-world activities and happenings, thus opening new frontiers in geosocial knowledge discovery. However, gleaning knowledge from geosocial media is a challenging task, as they tend to be unstructured and thematically diverse. In this presentation we will provide example applications to demonstrate the opportunities and challenges associated with the use of social media content in geospatial applications.
