Abstract : There is more and more commercial and research interest in nearest neighbor objects for location-based search from
spatial database. Spatial keyword search has been well studied for years due to its importance to commercial search engines.
Specially, a spatial keyword query takes a user location and user-supplied keywords as arguments and returns objects that is
nearest k objects from user current location and textually relevant to the user required keyword. In these systems,
inconsistencies and errors can exist in the user’s typed queries. To bridge the gap between queries and data, it is important to
support approximate keyword search on spatial database. In this paper we study how to answer such queries efficiently. A
number of geo-textual indices have been proposed in recent years which mainly combine the R-tree and its variants and the
inverted file. This paper proposes new index structure that combines K-d tree and inverted file. The proposed index structure
supports a wide range of query predicates efficiently. We also discuss approximate keyword search for the correct use’s
mistyped keywords.
