Abstract
A skyline query finds objects that are not dominatedby another object from a given set of objects. Skylinequeries can filter unnecessary information efficiently andprovide us important clues for various decision makingtasks. Now a days, GPS devices and location based servicesare very popular and they can easily connect users andmake groups. Conventional skyline queries are not sufficientto obtain valuable knowledge to fulfil the needs of suchgroups. Considering this fact, in this paper, we proposed aspatial skyline query for groups of users located at differentpositions. Our proposed skyline query algorithm selects a setof spatial objects to fulfil the groups’ needs. For example, ifa group wants to find a restaurant to hold a meeting, ourmethod can select a convenient place for all users of thegroup. We performed several extensive experiments to showthe effectiveness of our approach.
