• Topica is a mashup developed to support especially those end users who may have little to no knowledge about where to find information on nearby POI, but who are able to trigger a search based on their interests.

• Topica mashes up services coming from: – OpenCalais , Zemanta, Dbpedia and Dbpedia

Spotlight for providing an even richer annotation and to widen recall during information retrieval.

– Google Maps

• Topica provides a temporal-facet to the featuring of a POI.

• Dbedia Mobile [1] – Location-aware SW client, which based on the current geo coordinates

renders a map with near-by locations from the DBpedia data set.• Stevie Mobile [2]

– Allows users to share and browse temporal infor- mation about POIs events based on the location broadcast by end users’ GPS (Global Positioning System) on a map visualisation.
