Abstract:
Web-based geographic information search
engines are prominently used in recent years. Spatial
databases have both spatial and textual descriptions.
Geographic web search engine retrieves the nearest
objects that are the most textually and spatially
relevant according to the user required keywords.
Many number of spatial keyword query methods have
been proposed and a variety of applications has been
developed in GIS decision support system. This paper
proposes category based new combined index
structure which integrates R* tree and inverted file.
The proposed system can efficiently be used both
multidimensional points and spatial data. The
proposed system is capable for good performance
and reduces the storage cost.
