包括地理空间特征到互联网上的查询是可能的位置感知设备。另一方面，存在当前应用，其中用户有兴趣查看基于多个标准从大集合中选择的最佳对象。Skyline过滤掉那些最符合用户偏好的对象。地理位置和偏好的融合使得一种新的天际线查询成为可能，该查询同时考虑了位置邻近度和用户的偏好。基于位置的Skyline是Skyline的扩展，它依赖于感兴趣对象的地理位置。在这项工作中，我们已经开发了一个Web工具，显示基于位置的天际线查询的结果，并提出了一个新的算法来评估基于位置的天际线查询。我们的实验研究表明，我们提出的算法优于现有的算法，高维查询时，数据是不重复的。
Including geo-spatial features into queries over Internet is possible with location aware devices. On the other hand, there are current applications where a user is interested in viewing the best objects chosen from a large collection, based on multiple criteria. Skyline filters out those objects that best match user's preferences. The fusion of geo-location and preferences makes possible a new kind of Skyline queries that takes into account both location proximity and user's preferences. A location-based Skyline is an extension of Skyline, which depends on geographical locations of interest objects. In this work, we have developed a web tool that displays the results of a location-based Skyline query and propose a new algorithm to evaluate location-based Skyline queries. Our experimental study shows our proposed algorithm outperforms existing algorithms for high-dimensional queries when data are non-duplicated.
