Linking Benchmark for Spatial Data – Presentation in OM 2017

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 across knowledge bases. In most cases, the cross-dataset links are not explicit in the […]

Versioning for Big Linked Data: approaches and benchmarks

As LOD datasets are constantly evolving, both at schema and instance level, there is a need for systems that support efficiently storing and querying such evolving data. Such archiving systems must support various types of queries on data, including queries that access multiple versions (cross-version queries), queries that access the evolution history (delta) itself, as well as […]

Benchmarking RDF Query Engines – A mini-survey

Non-relational data management is starting to dominate the new data economy. Formats like XML, JSON and RDF are becoming the basis for data exchange in the Web and the Enterprise, and systems are constantly being developed for their support. For any such system to gain traction, it has to provide adequate support for its respective […]

HOBBIT @ EDF 2016

EDF 2016 is now over and HOBBIT was present in several functions. We disseminated the idea of a universal benchmarking platform to the many European organizations and research projects that were present at the forum. Potential collaborations were established with data-driven projects pertaining to geo-spatial data and societal challenges, which will be followed through. Beware […]

Upcoming Evaluation Campaigns powered by HOBBIT technologies, almost.

In a former blog post, we presented the predecessor of the HOBBIT platform, the General Entity Annotator Benchmarking Framework (GERBIL) [1]. This framework has been adopted by two evaluation campaigns as described in this post. These campaigns focus on tasks such as entity recognition, entity typing and question answering. Open Knowledge Extraction Challenge The OKE […]

The roots of HOBBIT: GERBIL

The idea of creating a platform to host different benchmarking tools for the Big Linked Data lifecycle was born with the creation of the General Entity Annotator Benchmarking Framework [1](GERBIL). GERBIL is designed to facilitate the benchmarking of named entity recognition (NER), named entity disambiguation (NED) and other semantic tagging approaches. GERBIL’s objective is to […]

Why Join the Hobbit Community?

Linked Data technologies are proving their efficiency in creating interoperable IT systems that integrate disparate data sources. However, it is still unclear which solutions scale up the needs of modern business applications. Benchmarks have been created to support decisions on choosing the best software solution. However, they commonly fail to reflect business requirements in terms […]
