geo location semantics
DESCRIPTION
Mobile location based applications have only begun to scratch the surface of what's possible. By leveraging semantics, or the relationships between things, location based applications can become much more powerful - and much more useful. This presentation shows how the Freebase Geo Search API can be used to implement simple, but powerful location + semantic patterns to power the next generation of mobile location based applications.TRANSCRIPT
