Efficient Index Based Query Keyword Search in the Spatial Database
نویسنده
چکیده
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.

An Effective Path-aware Approach for Keyword Search over Data Graphs
Abstract—Keyword Search is known as a user-friendly alternative for structured languages to retrieve information from graph-structured data. Efficient retrieving of relevant answers to a keyword query and effective ranking of these answers according to their relevance are two main challenges in the keyword search over graph-structured data. In this paper, a novel scoring function is proposed, w...

Important cloud services rely on spatial-keyword queries, containing a spatial predicate and arbitrary boolean keyword queries. In particular, we study the processing of such queries in main memory to support short response times. In contrast,current state-of-theart spatial-keyword indexes and relational engines are designed for different assumptions. Rather than building a new spatial-keyword ...

Spatial Data Mining (SDM) is the process of mining spatial databases. Spatial databases contain details of geographical objects. Spatial data is generally associated with non-spatial data as well. Queries on spatial databases can also predicates to obtain the required results. However, the predicates are pertaining to the geographical features of spatial objects. The applications that use spati...
