Paper Title
K-Nearest Neighbours Approximate Keyword Search For Spatial Database
Abstract
Keyword search over a large amount of data is an important operation in a wide range of domains. Nearest neighbor
objects with required for location-based search from spatial database has been well studied for years due to its importance to
commercial search engines. Specially, the top-k 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. This paper proposes new index
structure that combines K-d tree and inverted file to answer such query efficiently and we also discuss how to answer the
queries that contain the user typing error in keyword.
