Efficient Index Based Query Keyword Search in the Spatial Database

摘要

In many real time applications there is a need to represent many real time objects (universities, temples, airports, cities, buildings, lakes and companies etc) in the spatial database. Usually, spatial database objects are mapped with keywords for their reference in business or service applications. Normally, spacial objects are queried with the requirement of minimum inter object distance. Nowadays many business decisions are directly related to the keyword rating of objects. Existing method considers inter object distance only. Many latest methods require not only the inter object distance but also object ratings for increasing their revenues. More generalized version of spatial keyword search requires both inter object distance as well as keyword ratings.
