天际线查询从给定的一组对象中查找不受另一个对象支配的对象。Skyline查询帮助我们有效地过滤不必要的信息，并为我们提供各种决策任务的线索。本文提出了一种计算空间天际线对象（如酒店）的方法。传统的天际线查询基于酒店的非空间属性（如价格和评级）来选择酒店。然而，他们并没有很好地利用周围的环境。相比之下，所提出的方法在选择skyline酒店时考虑了每家酒店的周边设施，如酒店附近的餐厅和超市。就像酒店的例子一样，当我们在数据库中选择一个空间对象时，周围环境与其他属性一样重要。因此，提出的天际线查询功能对空间数据库具有重要意义。
A skyline query finds objects that are not dominated by another object from a given set of objects. Skyline queries help us to filter unnecessary information efficiently and provide us clues for various decision making tasks. In this paper, we present a method for computing spatial skyline objects such as hotels. Conventional skyline queries select hotels based on non-spatial attributes of hotels such as price and rating. However, they do not utilize surrounding environments well. In contrast, the proposed method takes into account surrounding facilities of each hotel such as restaurants and supermarkets that are close to the hotel when we select skyline hotels. Like the hotel example, when we select a spatial object in a database, surrounding environment is as important as other attributes. Therefore, the proposed skyline query function is significant for spatial databases.
