Efficient Evaluation of Imprecise Location-Dependent Queries
2007
2007 IEEE 23rd International Conference on Data Engineering
In location-based services, it is common for a user to issue a query based on his/her current position. One such example is "find the available cabs within two miles of my current location". Very often, the query issuers' locations are imprecise due to measurement error, sampling error, or message delay. They may also want to protect their privacy by providing a less precise location. In this paper, we study the efficiency of queries that return probabilistic guarantees for location data with
