The number of datasets published in the Web of Data as part of the Linked Data Cloud is constantly increasing. The Linked Data paradigm is based on the unconstrained publication of information by different publishers, and the interlinking of web resources through “same-as” links which specify that two URIs correspond to the same real world object. In the vast number of data sources participating in the Linked Data Cloud, this information is not explicitly stated but is discovered using instance matching techniques and tools.
On the second day of the 6th LDBC TUC Meeting that took place in Barcelona we welcomed Yinglong Xia from IBM Research with his presentation “Recent Updates on IBM System G – GraphBIG and Temporal Data”.
In this post we will look at running the LDBC Social Network Benchmark (SNB) on Virtuoso.
Peter Haase from Metaphacts kicked-off the afternoon presentations during last LDBC TUC Meeting in Barcelona with the presentation "Querying the Wikidata Knowledge Graph"
Next 31st of May the GRADES workshop will take place in Melbourne within the ACM/SIGMOD presentation. GRADES started as an initiative of the Linked Data Benchmark Council in the SIGMOD/PODS 2013 held in New York. Read more information about the event here.
Note: this post is a continuation of "SNB Interactive Part 1 - What is SNB Interactive Really About?" post by Orri Erling.
SNB Interactive is the wild frontier, with very few rules. This is necessary, among other reasons, because there is no standard property graph data model, and because the contestants support a broad mix of programming models, ranging from in-process APIs to declarative query.
LDBC is presenting two papers at the next edition of the ACM SIGMOD/PODS conference held in Melbourne from May 31st to June 4th, 2015. The annual SCM SIGMOD/PODS conference is a leading international forum for database researchers, practitioners, developers, and users to explore cutting-edge ideas and results, and to exchange techniques, tools and experiences.
During last TUC Meeting in Barcelona we were glad to welcome Mark D. Wilkinson from Universidad Politécnica de Madrid with his presentation "SADI: A design-pattern for “native” Linked-Data Semantic Web Services".
Check the slides and video to learn more about how SADI uses OWL and RDF and about SHARE the health research environment that answers SPARQL queries with SADI.
This post is the first in a series of blogs analyzing the LDBC Social Network Benchmark Interactive workload. This is written from the dual perspective of participating in the benchmark design and of building the OpenLink Virtuoso implementation of same.
The second part of presentations during the first day at the TUC Meeting in Barcelona started with the presentation from Jerven Bolleman from the Swiss Institute of Bioinformatics called "20 billion triples in production".
Watch Jerven Bolleman talking about why and how the Uniprot SPARQL endpoint allows working with billion of triples from biological datasets.
