Implementing Graph Transformation Languages using RDF Storage and SPARQL Queries
RDF has so far not been widely used in the context of graph rewriting tools. In this paper, the authors take AToMPM, a research-oriented meta-modelling [...]
Recognizing, Naming and Exploring Structure in RDF Data
This master's thesis seeks to apply research into RDBMS - which has led to mature techniques for storing and querying data - to the problem [...]
The Berlin SPARQL Benchmark
This article introduces the Berlin SPARQL Benchmark (BSBM) for comparing the performance of native RDF stores with the performance of SPARQL-to-SQL rewriters across architectures. The [...]
Introduction to: Triplestores
This brief weblog entry describes the differences between triple stores and relational database systems. It also discusses the similarities and differences with NoSQL Graph databases. [...]
Integrating Open Sources and Relational Data with SPARQL
The authors of this paper believe that the possibility to use SPARQL as a front end to heterogeneous data without significant cost in performance or [...]
Practical RDF Schema Reasoning with Annotated Semantic Web Data
Semantic Web data with annotations is becoming available, with the YAGO knowledge base a prominent example. This video discusses an approach to performing the closure [...]
Capturing Relational Schemas and Functional Dependencies in RDFS
Mapping relational data to RDF is an important task for the development of the Semantic Web. To this end, the W3C has recently released a [...]
Dynamic Querying of Mass-Storage RDF Data with Rule-Based Entailment Regimes?
SPARQL is the W3C standard for querying RDF data, but it mostly provides means for querying simple RDF graphs only, whereas querying with respect to [...]
