WikiCite is an ongoing effort to build an extensive bibliographic database in Wikidata to serve all Wikimedia projects. While the idea has been around for over a decade, the technology needed to sustain this effort is maturing, and the immediate goal of the initiative to produce a well-curated, high-quality structured dataset of all sources cited across Wikimedia projects in Wikidata is taking sha...

Wikidata is a great project towards mapping structured information about the world, and exhibits a high degree of correctness. Its degree of completeness, in turn, is much less understood. Anecdotal evidence suggests that it covers many popular topics quite well, but there are few standard means that help in this assessment: At present, editors and consumers have to analyze largely on a case-by-ca...

Europeana offers a trusted repository of cultural heritage objects on the Web. One of our missions is to facilitate the re-use of cultural heritage metadata and content by third parties. In order to do so, it is crucial for the metadata and content described in Europeana to be semantically rich, multilingual and re-usable. A better integration with Wikidata is therefore a key priority.[1] Wikidata...

More than 1.4M monument have been gathered from more than 70 countries across the world since the inception of Wiki Loves Monuments in 2010.

Specific data is usually hard to find and it remains a challenge to link and connect the information already available. As a...

Wikidata are growing and expanding. So they are inevitable facing different problems and challenges. Aim of the discussion is at least to identify these problems and challenges. Main themes may be: scalability - both macro (database) and micro (item) level vandalism - as internal (incorrect data) and external problem (Wikidata credibility) multilinguality - fact or just a dream references - necess...

After you have convinced an institution to donate data (or, if you are an institution: after you have been convinced) the real fun starts — how to upload all the data? Wikidata lacks a big friendly upload button, but that should not put you off. We'll look at various parts of a typical workflow: collecting data (copyright! data base right! fun!) cleaning data (repairing faulty data with Google Spr...

It makes extensive use of the Wikidata Query Service. It attempts to make a complete researcher profile/CV as well as a tool to...

Data quality is an important topic for Wikidata, as the number of initiatives and projects around this topic testifies. To name just a few, the Item quality campaign relied on the work of the community to evaluate Items using a single-grading label scheme. The CoolWD project focuses on a particular dimension of quality, providing users with information about the completeness of the results of a qu...

This session is a workshop intended to bring together Wikidata wizards and enthusiasts who can help resolve some of the major pain points in the data import process. For example: It’s very difficult to keep Wikidata ‘in sync’ with an external data source (especially when they have no unique ID system!). There’s no way to easily report metrics related to a particular data import. It’s hard to find...

Wikidata, the knowledge base of structured data that anyone can edit, has roughly 16,000 active editors. The number of editors is growing steadily. How can we support hundreds of thousands, or even millions, of editors? One strategy is to create contribution pathways that reduce the barriers of entry for newcomers. We introduce Wikidata for Digital Preservation, a portal that allows users to curat...

When researchers publish scientific articles some include information about software used in their research. In traditional publication models the rare occasions in which research software is provided along with a publication, the links between those research outputs are not always easily maintained. Funders, publishers, scholars, librarians, and other information professionals need ways to descri...

The goal of this discussion is to allow people doing research on/with Wikidata to define a list of things that could be improved to make Wikidata more research-friendly. This would allow volunteer contributors to have ideas of things they could hack on. This discussion will also be a place to share existing tips and tools that helps doing research on/with Wikidata. about this event: https://c3voc....

One of the major challenges faced in Wikidata, like in any crowdsourcing project, is to attain a high level of editor engagement. There is a clear need for attracting new editors and growing the community, but at the same time, retaining existing editors is also crucial for the success of Wikidata. While Wikidata has currently thousands of active editors, only a few of them are power users who per...
