An Introduction to Wikidata

Tue, 17 Jan 2017 06:46:13 +0000

Describes Wikidata, a "free and open knowledge base" which houses the data formerly located at Google's Freebase. Discusses how Wikidata is well-placed to solve data provenance issues on the Web, such as those currently faced by Google's Knowledge Graph. Wikidata is machine-readable, open source, and multilingual. In addition, it assigns unique identifiers to resources and describes those resources using statements.

The author of this blog post states his opinion that "the world has too many ontologies and not enough useful data for those ontologies to describe", then seeks to help remedy the situation by sharing some scripts he wrote which search the Web (via a Google API) to find RDF data.

Providing Linked Data

Sun, 23 Oct 2016 05:39:27 +0000

This module covers the whole spectrum of Linked Data production and exposure. After a grounding in the Linked Data principles and best practices, with special emphasis on the VoID vocabulary, it covers R2RML, operating on relational databases, Open Refine, operating on spreadsheets, and GATECloud, operating on natural language. Finally it describes the means to increase interlinkage between datasets, especially the use of tools like Silk.

The Linking Open Data Cloud Diagram

Thu, 20 Oct 2016 05:39:11 +0000

This web page is the home of the LOD cloud diagram. This image shows datasets that have been published in Linked Data format, by contributors to the Linking Open Data community project and other individuals and organisations. It is based on metadata collected and curated by contributors to the Data Hub as well as on metadata extracted from a crawl of the Linked Data web conducted in April 2014. Clicking the image will take you to an image map, where each dataset is a hyperlink to its homepage.

Open Data Communities Data Catalogue

Sat, 16 Jan 2016 13:43:28 +0000

This is a catalogue of links to over 100 datasets which appear to be complete with in-depth descriptions and metadata. They have been provided by the UK Department for Communities and Local Government as part of its Open Data Strategy- a commitment to routinely releasing data outputs in fully open, accessible and re-usable forms. The datasets are provided under the OGL (Open Government Licence). Many of the datasets themselves are downloadable as N-Triples; all of the metadata for each dataset is available in the most common machine-readable formats (including JSON, RDF/XML, Turtle). The Open Data Communities home page also has a link to a SPARQL endpoint.
