RDF and Graph benchmarking project started: LDBC

This week we received notification from the EU that the LDBC project has been granted. We think this is great news. The LDBC project (is a STREP and will run until Q2 2015. LDBC stands for Linked Data Benchmark Council, and linked data here of course comprises RDF data management, but also includes the emerging class of […]

EU confirmes the start of LDBC.

November 9, 2012, the EU confirmed the start of the new FP7 project called Linked Data Benchmark Council (LDBC). The main objective of LDBC is the development of benchmarks for the emerging field of RDF and graph data management systems, as well as to spur industry cooperation around such benchmarks. This new council of database […]

Update: Complexity, Learning and Semantics

Source: Data2Semantics Complexity metrics form the backbone of graph analysis. Centrality, betweenness, assortativity and scale freeness are just a handful of selections from a large and quickly growing literature. It seems that every purpose has its own notion of complexity. Can we find a way to tie these disparate notions together? Algorithmic statistics provide an […]

Update: TabLinker & UnTabLinker

Source: Data2Semantics TabLinker, introduced in an earlier post, is a spreadsheet to RDF converter. It takes Excel/CSV files as input, and produces enriched RDF graphs with cell contents, properties and annotations using the DataCube and Open Annotation vocabularies. TabLinker interprets spreadsheets based on hand-made markup using a small set of predefined styles (e.g. it needs to […]

Update: Machine Learning and Linked Data

Source: Data2Semantics Part of work package 2 is developing machine learning techniques to automatically enrich linked data. The web of data has become so large, that maintaining it by hand is no longer possible. In contrast to existing techniques for learning for the semantic web, we aim at applying the techniques directly to the linked data. We use kernel […]

Update: Provenance Reconstruction

Source: Data2Semantics Work package 5 of Data2Semantics focuses on the reconstruction of provenance information. Provenance is a hot topic in many domains, at it is believed that accurate provenance information can benefit measures of trust and quality. In science, this is certainly true. Provenance information in the form of citations is a centuries old practice. […]

Update: Linked Data Replication

Source: Data2Semantics What if Dolly was only a partial replica? Work package 3 of Data2Semantics centers around the problem of ranking Linked Data. Over the past year, we have identified partial replication as a core use case for ranking. The amount of linked data is rapidly growing, especially in the life sciences and medical domain. At […]
