摘要

RDF(资源描述框架)数据集的增长及其使用的扩展与SPARQL(一种声明性查询语言)的定义相结合，使RDF数据管理成为一个活跃的研究和开发领域。在这方面，已经提出了一些机制来帮助用户在更短的时间内找到他们想要的答案，包括排名方法和基于偏好的查询。Skyline查询是最实用、最主要的基于偏好的查询类型之一。这项工作的目的是提供一个指南，说明如何使用最新作品和SPARQL 1.0和1.1版本中提出的语法来指定SPARQL天际线查询。结果显示了在SPARQL中重写skyline查询以表达偏好的可能性。我们计划开发一个工具，将SPARQL天际线查询应用所提出的不同语法翻译成SPARQL 1.0和1.1，目的是提供一种自动翻译机制。

Skyline Queries in SPARQL: An Overview

The growth of RDF (Resource Description Framework) datasets and the expansion of their use in conjunction with the definition of SPARQL, a declarative query language, have made RDF data management an active area of research and development. In this regard,mechanisms have been proposed to help users find their desired answers in less time, including ranking methods and preference-based queries. Skyline queries constitute one of the most practical and predominant types of preference-based queries. The aim ofthis work was to provide a guide to specifying SPARQL skyline queries using syntax proposed in state-of-the-art works, and SPARQL versions 1.0 and 1.1. The results show the possibility of rewriting skyline queries in SPARQL to express preferences. We planto develop a tool to translate SPARQL skyline queries applying the different grammars proposed, into SPARQL 1.0 and 1.1 with the aim of providing an automatic mechanism of translation.
