RDFBroker: A Signature-Based High-Performance RDF Store [chapter]

Michael Sintek, Malte Kiesel
2006 Lecture Notes in Computer Science  
In this paper we propose an RDF store that uses a natural mapping of RDF resources to database tables that does not rely on RDF Schema, but constructs a schema based on the occurring signatures, where  ...  A first prototype has been implemented and already shows a significant performance increase compared to other freely available (inmemory) RDF stores.  ...  This work has been supported in part by the SmartWeb project, which is funded by the German Ministry of Education and Research under grant 01 IMD01 A, and by the NEWS project, which is funded by the IST  ...

Categorization of RDF Data Management Systems

Khadija Alaoui, Mohamed Bahaj
2021 Advances in Science, Technology and Engineering Systems  
To this end, we give an extended categorization of RDF data stores according to their main characteristics.  ...  It is therefore a necessity for users to be able to distinguish between these systems to decide about the appropriate triplestore for an efficient processing of their RDF data depending on their objectives  ...  FlexTable [20] and RDFBroker [21] are examples of such stores. RDFBroker is based on occurring predicates signatures in RDF data.  ...

A Survey of RDF Stores SPARQL Engines for Querying Knowledge Graphs [article]

Waqas Ali, Muhammad Saleem, Bin Yao, Aidan Hogan, Axel-Cyrille Ngonga Ngomo
2021 arXiv   pre-print
This survey paper provides a comprehensive review of techniques and systems for querying RDF knowledge graphs.  ...  RDF has seen increased adoption in recent years, prompting the standardization of the SPARQL query language for RDF, and the development of local and distributed engines for processing SPARQL queries.  ...  RAP RDFBroker [212] (2006) is an RDF store that follows a property table approach.  ...

RDFProv: A relational RDF store for querying and managing scientific workflow provenance

Artem Chebotko, Shiyong Lu, Xubo Fei, Farshad Fotouhi
2010 Data & Knowledge Engineering  
The comparison with two popular relational RDF stores, Jena and Sesame, and two commercial native RDF stores, AllegroGraph and BigOWLIM, showed that our optimizations result in improved performance and  ...  In this paper, we elaborate on the design of a relational RDF store, called RDFProv, that is optimized for scientific workflow provenance querying and management.  ...  RDF store RDFBroker [100] implements signature relations, which are conceptually similar to clustered property relations, but are generated based on RDF data rather than RDF Schema information.  ...

An Intermediate Algebra for Optimizing RDF Graph Pattern Matching on MapReduce [chapter]

Padmashree Ravindra, HyeongSik Kim, Kemafor Anyanwu
2011 Lecture Notes in Computer Science  
A comparative performance evaluation of the traditional Pig approach and RAPID+ (Pig extended with NTGA) for graph pattern matching queries on the BSBM benchmark dataset is presented.  ...  This cost is prohibitive for RDF graph pattern matching queries which typically involve several join operations.  ...  RDFBroker [21] is a RDF store that is based on the concept of a signature (set of properties of a resource), similar to NTGA's structurelabeling function λ.  ...
