Abstract
Currently the keyword queries in spatiotemporal database are the simple traditional query mostly.With the further development of location-based service ( LBS) , new type applications emerge as well, in these new applications the objects do not only contain position in-formation, but also contain location-related text information such as name, style and so on, so traditional query is no longer applicable.In or-der to be able to handle spatiotemporal query efficiently, this paper proposes a novel spatiotemporal keyword query, known as the reverse ag-gregate nearest keyword query.关键词
