Paper – Wikidata: a platform for your library’s linked open data

Wikidata: a platform for your library’s linked open data by Stacy Allison-Cassin, Dan Scott. code{4}lib Issue 40, 2018-05-04

“Creating and using linked open data (LOD) in library and GLAM (galleries, libraries, archives, museums) projects has historically been associated with a high level of institutional requirements. Erik et al (2015) asserted “the fact that LAM institutions are still having to select triplestores, SPARQL engines, indexing platforms, and other services means that there is still a relatively high bar for institutions to cross in taking up LD projects”. The requirement to select, host, and administer all of these systems establishes technical and resource barriers that can prevent organizations and individuals from participating in LOD entirely (Goddard and Byrne, 2010). Creating and publishing LOD has traditionally required technical skills to transform relational data, to support content-negotiation and alternate serializations, and to understand vocabularies and ontologies typically documented in RDFS or OWL. Wikidata, launched in 2012 by the Wikimedia Foundation as the machine-readable store for all Wikimedia Foundation projects, is a freely available hosted platform that anyone–including libraries–can use to create, publish, and use LOD. Powered by Blazegraph, the platform offers a triplestore and high-availability SPARQL endpoint that (as of April 2018) has served roughly 3 million queries per day over the past year (Wikimedia Foundation, n.d.); a full text search engine; and is administered by the Wikimedia Foundation. Its vocabulary is published and editable alongside other items in the platform using the same relatively user-friendly interfaces. In effect, Wikidata has responded to the barriers identified by Erik et al and Goddard and Byrne by providing a ready-made platform for any person or organization that wants to create, publish, and use LOD, including libraries. In their 2016 IFLA discussion paper, Bartholomei et al noted “[t]he potential of Wikidata to draw linked open data and linked open data authorities together across the world’s languages and many different ontologies and taxonomies has enormous potential to support researchers around the world.” The platform is increasingly important as a general LOD resource and as a “linking hub”, recognized in 2013 by Klein and Kyrios as they worked on integrating VIAF data into Wikipedia [7]. At the first Wikidata Conference, van Veen (2017) boldly suggested Wikidata could be both a linking hub and source of library authority data. As of February 2018, Wikidata now offers links to external data with more than 2,500 identifiers. An international, multilingual, community-based project, Wikidata is a practical choice for use by libraries, and requires all contributions to be licensed under the Creative Commons CC0 “No rights reserved” licence. This licence allows the contents (49 million items as of February 2018) to be used in any project without the cumbersome attribution requirements of other open data licenses, and ensures that every contribution to the repository broadens the range of freely available data…”

What are the ten most cited sources on Wikipedia? Let’s ask the data.

Wikimedia: “Citations are the foundation of Wikipedia’s reliability: they trace the connection between content added by our community of volunteer contributors and its sources. For readers, citations provide a mechanism to validate and check for themselves that what Wikipedia says is sound and trustworthy: they act as a gateway towards a broader ecosystem of reliable… Continue Reading

200,000 Volunteers Have Become the Fact Checkers of the Internet

NexrGov: The creation process of Wikipedia is largely transparent – “Founded in 2001, Wikipedia is on the verge of adulthood. It’s the world’s fifth-most popular website, with 46 million articles in 300 languages, while having less than 300 full-time employees. What makes it successful is the 200,000 volunteers who create it, said Katherine Maher, the… Continue Reading

Paper – The Evolution of Wikipedia’s Norm Network

The Evolution of Wikipedia’s Norm Network – Bradi Heaberlin and Simon DeDeoFuture, Internet 2016, 8(2), 14; doi:10.3390/fi8020014 “Social norms have traditionally been difficult to quantify. In any particular society, their sheer number and complex interdependencies often limit a system-level analysis. One exception is that of the network of norms that sustain the online Wikipedia community.… Continue Reading

From Freebase to Wikidata: The Great Migration

“Collaborative knowledge bases that make their data freely available in a machine-readable form are central for the data strategy of many projects and organizations. The two major collaborative knowledge bases are Wikimedia’s Wikidata and Google’s Freebase. Due to the success of Wikidata, Google decided in 2014 to offer the content of Freebase to the Wikidata… Continue Reading
