论文摘要
Skyline和Top-K是从数据集中提取信息的两种最重要的方法，但两者都有缺点，这就是为什么最近已经研究了一些尝试混合两者的功能的新技术的原因。在这项调查中，分析了三个新运营商，F-Skyline，Oru/Ord和$ε$ -SKYLINE。在给出了这些主要想法及其属性背后的主要想法之后，它们汇编了3个基本特征，例如个性化，心脏控制和概括，以指导用户为任何任务选择最佳的功能。
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.
