TsingNUS: A Location-Based Service System Towards Live City
Summary: TsingNUS crawls and cleans location-based UGC (Foursquare, Twitter) into well-structured geodata for live-city search. It introduces three location-aware paradigms: instant search, fuzzy similarity search, and direction-aware search, plus continuous search to support moving queries and reduce client-server traffic; the system is implemented and deployed.
