An Efficient I/O Cost Model for Novel Indexing algorithms in a Joint Top K Spatial Keyword Query Processing

Abstract

A Top-k spatial keyword query returns the k best objects ranked in terms of both distance to the query location and textual relevance to the query keywordsThe Web users and Web content are increasingly being geo-positioned such as GPS and WIFI. It also focuses to convert local content in response to web queries. Ittake into an account of both the locations and textual descriptions of content. In order to process such queriesefficiently, spatial-textual indexes combining R-trees and inverted files are employed. The studies deal with an efficient joint processing of multiple top-k spatial keyword queries with cost model for Novel Algorithms. The joint processing is deals a high query loads and also occurs when multiple queries are used to obfuscate a user’s true query. The Novel algorithm with an index structure for the joint processing of top-k spatial keyword queries are proposed with an efficient cost model.
