灵活/受限天际线及其适用性研究综述
A survey on flexible/restricted skyline and their applicability
摘要：
Skyline和Top-k是从数据集中提取信息的两种最重要的方法，但都有各自的缺点，这就是为什么最近研究了一些尝试混合这两种特征的新技术。在这项调查中，分析了三个新的运营商，F-Skyline，ORU/ORD和$ε$ -Skyline。在给出这些背后的主要思想及其属性后，对它们进行个性化、基数控制和泛化等3个基本功能的比较，以指导用户为任何任务选择最佳功能。
英文摘要：
Skyline and Top-k are two of the most important methods to extract information from datasets, but both come with their drawbacks, that's why lately some new technics that try to mix the features of the two have been studied. In this survey three new operators are analysed, F-Skyline, ORU/ORD, and $ε$-Skyline. After giving the main ideas behind those and their properties, they are compered on 3 fundamental features such as personalization, cardinality control, and generalization to guide the user to choose the best one for any task.
