Diversified Stress Testing of RDF Data Management Systems
The Resource Description Framework (RDF) is a standard for conceptually describing data on the Web, and SPARQL is the query language for RDF. As RDF data continue to be published across heterogeneous domains and integrated at Web-scale such as in the Linked Open Data (LOD) cloud, RDF data management systems are being exposed to queries that are far more diverse and workloads that are far more v...
متن کاملSurvey of RDF data on the Web
The Resource Description Framework (RDF) allows describing metadata in an interoperable way. It is the basis for promising work in the area of the Semantic Web. This paper assesses how much and what kind of RDF data was found on the web in December 2001 and in August 2002. Four search strategies, crawling, scanning URLs obtained from an Internet Directory, a targeted search, and a search at URL...
متن کاملEfficient Management of Spatial RDF Data
The RDF data model has recently been extended to support representation and querying of spatial information (i.e., locations and geometries), which is associated with RDF entities. Still, there are limited efforts towards extending RDF stores to efficiently support spatial queries, such as range selections (e.g., find entities within a given range) and spatial joins (e.g., find pairs of entitie...
متن کاملA Survey of State Management in Big Data Processing Systems
The management and usage of state are issues of paramount importance in big data processing systems (BDPS) today. They are increasingly gaining attention due to their utility in supporting complex operations in various applications. In this paper, we survey state management in BDPS and introduce a taxonomy to classify current research in this field by key characteristics. Firstly, we present so...
