摘要:

在过去的几年里,越来越多的关联数据及其固有的分布式特性引起了整个研究界和从业者对数据搜索的极大关注。受传统分布式数据库研究成果的启发,介绍了在SPARQL端点上管理联邦的不同方法。SPARQL是RDF的标准化查询语言,RDF是链接数据部署中使用的默认数据模型,SPARQL端点是许多链接开放数据(LOD)存储库提供的流行访问机制。在本文中,我们首先概述了联邦框架的基础设施,然后继续与现有的SPARQL联邦框架的比较。最后,我们强调了现有框架的缺点,我们希望这有助于催生新的研究方向。

英文摘要:

The increasing amount of Linked Data and its inherent distributed nature have attracted significant attention throughout the research community and amongst practitioners to search data, in the past years. Inspired by research results from traditional distributed databases, different approaches for managing federation over SPARQL Endpoints have been introduced. SPARQL is the standardised query language for RDF, the default data model used in Linked Data deployments and SPARQL Endpoints are a popular access mechanism provided by many Linked Open Data (LOD) repositories. In this paper, we initially give an overview of the federation framework infrastructure and then proceed with a comparison of existing SPARQL federation frameworks. Finally, we highlight shortcomings in existing frameworks, which we hope helps spawning new research directions.
