Efficient Processing of Location-Aware Group Preference Queries

Abstract

With the proliferation of geo-positioning techniques that enable users to acquire their geographical positions, there has been increasing popularity of online location-based services. This development has generated a large volume of points of interest labeled with category features (e.g., hotel, resort, stores, stations, and tourist attractions). It gives prominence to various types of spatial-keyword queries, which are employed to provide fundamental querying functionality for location-based services.
