Sticker: Searching and Aggregating User-Generated Contents along with Trajectories of Moving Phenomena

With the advance of the Web technologies, people can more easily access the geographic information and generate various types of user contents including geo-information on the Web. Consequently, geo-web and geo-communities have been infrastructures to share and connect information on the Web for many years, and people start to describe a specific phenomenon on places by own representation methods such as text, images, videos, etc. In this demonstration, we introduce a new type of location-based services, called Sticker, which can search and aggregate the relevant user generated contents/media to moving phenomena such as hurricanes, flooding, and global warming. In particular, the Sticker navigates user-generated contents with three dimensional view of space-time(2D+1D) and allows users to retrieve related information with the moving phenomena in a spatiotemporal domain as well as interesting keywords.
