A survey of RDF storage approaches
TLDR
The Semantic Web extends the principles of the Web by allowing computers to understand and easily explore the Web. Expand
Ontology Based Data Integration Over Document and Column Family Oriented NOSQL
TLDR
The World Wide Web infrastructure together with its more than 2 billion users enables to store information at a rate that has never been achieved before. Expand
SPARQL Graph Pattern Processing with Apache Spark
TLDR
We study the use of two distributed join algorithms, partitioned and broadcast join, for the evaluation of BGP expressions on top of Apache Spark. Expand
Design of a Domain Specific Language for modelling processes in landscapes.
TLDR
The modelling of processes that occur in landscapes is often confronted to issues related to the representation of space and the difficulty of properly handling time and multiple scales. Expand
SPARQL query processing with Apache Spark
TLDR
The number of linked data sources and the size of the linked open data graph keep growing every day. Expand
Data Integration over NoSQL Stores Using Access Path Based Mappings
TLDR
In this paper, we adapt a framework encountered for the integration of relational data to a broader context where both NoSQL and relational databases can be integrated. Expand
WaterFowl: A Compact, Self-indexed and Inference-Enabled Immutable RDF Store
TLDR
In this paper we present WaterFowl, a novel approach for the storage of RDF triples that addresses scalability issues through compression. Expand
RDF Database Systems: Triples Storage and SPARQL Query Processing
TLDR
RDF Database Systems is a cutting-edge guide that distills everything you need to know to effectively use or design an RDF database. Expand
Strider: An Adaptive, Inference-enabled Distributed RDF Stream Processing Engine
TLDR
We propose an inference-enabled SPARQL AQP for real-time processing of data streams emanating from sensors. Expand
On the Evaluation of RDF Distribution Algorithms Implemented over Apache Spark
TLDR
This paper presents an in-depth analysis and experimental comparison of five representative and complementary distribution approaches for RDF data distribution with predefined query workloads. Expand
