In this post, I will discuss in some detail the rationale and goals of the design of the Social Network Benchmark (SNB) and explain how it relates to real social network data as in Facebook, and in particular FaceBook's own graph benchmark called LinkBench. We think SNB is the most intricate graph database benchmark to date (it's also available in RDF!), that already has made some waves. SNB recently receiv
Social Network interaction is amongst the most natural and widely spread activities in the internet society, and it has turned out to be a very useful way for people to socialise at different levels (friendship, professional, hobby, etc.). As such, Social Networks are well understood from the point of view of the data involved and the interaction required by their actors.
LDBC is proud to announce that Andrey Gubichev and his colleagues of TUM won the graph analytics-targeted SIGMOD 2014 programming contest. In the presentation to the plenary SIGMOD/PODS room, the LDBC Social Network Benchmark data generator, which was used in this contest, was explicitly named, thanked and praised.
The Linked Data Benchmark Council (LDBC) is reaching a milestone today, June 23 2014, in announcing that two of the benchmarks that it has been developing since 1.5 years have now reached the status of Public Draft. This concerns the Semantic Publishing Benchmark (SPB) and the interactive workload of the Social Network Benchmark (SNB). In case of LDBC, the release is staged: now the benchmark software just runs read-only queries. This will be expanded in a few weeks with a mix of read- and insert-queries. Also, query validation will be added later.
The focus of this new workshop is to elicit discussion and description of application areas and open challenges in managing large-scale graph-shaped data.
Experiences including use-case descriptions, war stories and benchmarks as well as system descriptions are important ingredients of the meeting.
The workshop is co-chaired by Josep Larriba Pey (UPC) and Peter Boncz (CWI).
The LDBC consortium are pleased to announce the fourth Technical User Community (TUC) meeting. This will be a one-day event at CWI in Amsterdam on Thursday April 3, 2014.
The event will include:
Following the 1st International workshop on Benchmarking RDF Systems (BeRSys 2013) the aim of the BeRSys 2014 workshop is to provide a discussion forum where researchers and industrials can meet to discuss topics related to the performance of RDF systems. BeRSys 2014 is the only workshop dedicated to benchmarking different aspects of RDF engines - in the line of TPCTC series of workshops.The focus of the workshop is to expose and initiate discussions on best practices, different application needs and scenarios related to different aspects of RDF data management.
It is with great pleasure that we announce the new LDBC organisation site at www.ldbcouncil.org. The LDBC started as a European Community FP7 funded project with the objective to create, foster and become an industry reference for benchmarking RDF and Graph technologies.
Graph-TA, organized by DAMA-UPC (Data Management) group of Universitat Politècnica de Catalunya – BarcelonaTech, aims at encouraging researchers to present their current work and interact in an informal set up in order to foster collaboration with other colleagues. Thus, the workshop will provide a forum for presenting and discussing research results and applications in the domain of graphs from different communities, i.e.
