Spatial semantic search in location-based web services
Jeong-Hoon Park · 2014
As GPS-enabled mobile devices have advanced, the location-based service(LBS) became one of the most active subjects in the Web-based services. Major Web-based services such as Google Picasa, Twitter, Facebook, and Flicker employ LBS as one of their main features. Consequently, a large number of geotagged documents are generated by users in the Web-based services. Recently, there have been studies on the spatial keyword search which aims to find a set of documents in the Web-based services by evaluating the spatial relevance and keyword relevance. It is a combination of the spatial search and keyword search, each of which has been studied for a long time.
