Scholia profile of a topic


Scholia (Q45340488) View profile on Scholia is a project to present bibliographic information and scholarly profiles of authors and institutions using Wikidata, the community-curated database supporting Wikipedia and all other Wikimedia projects. Scholia is being developed in the framework of the larger WikiCite initiative, which seeks to index bibliographic metadata in Wikidata about resources that can be used to substantiate claims made on Wikidata, Wikipedia or elsewhere.

Using Scholia[edit]

Main tool[edit]

A Scholia profile for a person

Access the Scholia tool at The menu bar lists "author", "work", "organization", "topic", and suggested other data visualization options. Anyone who wishes to see a scholarly profile of a researcher based on Wikidata information about their publications may search for their name in the "author" presentation. For a Wikidata profile of a publication, search "work", and so on for the others.

Creating a scholarly profile[edit]

When Wikidata has an item entry for a person and item entries for at least some of their publications, then Scholia will use that information to generate a scholarly profile. Anyone wishing to create a scholarly profile with Scholia should edit the Wikidata item for that person in the usual way of engaging with Wikidata. In addition to editing the item for individuals, one should provide Wikidata with a list of that person's publications with appropriate structured data indicating that they are an author of these publications.

Contributing bibliographic data[edit]

Wikidata is seeking structured metadata for academic publications. The project through which the Wikimedia community is managing the social, technical, data accession, and data implementation issues for citations is WikiCite. While smaller data experiments on the order of perhaps hundreds of publications are appropriate for anyone to upload, anyone engaged in large-scale citation upload should join the Wikicite community to review the thousands of pages of documentation and content describing the complicated relationship between Wikipedia, Wikidata, and citations to everything ever published.

To contribute enough data to create scholarly profiles for a few individuals, then collect the digital object identifier (Q25670)s for their publications and upload them to Wikidata using any of the tools which format citations for Wikidata. WikiProject Source MetaData presents tools including fatameh and Source MetaData.

Other visualizations[edit]

Scholia offers visualizations for publications, organizations, and other entities. The model for preparing visualizations for any of these is the same as for an individual researcher: first set up a Wikidata item for the entity to profile, then upload citations to publications which have structured data noting the relationship of the publication to the entity to profile. For instance, items about publications that have a main subject (P921) statement will appear in the "topic" visualization (example: Zika virus).

Use as a reference manager[edit]

Scholia integrates with BibTeX (Q8029), i.e. from inside TeX (Q5301) or LaTeX (Q5310) documents, a particular reference can be cited by just using their Wikidata identifier, through which Scholia can retrieve the bibliographic metadata that BibTeX can process to format the output according to the style file defined in the document.

Scholia provides a visualization and access to data which many researchers find useful and which otherwise would either be expensive, labor intensive, or use commercial closed data to access.

How it works[edit]

Scholia uses various other Wikidata functions to operate. To make a profile, it executes a set of queries using the Special:MyLanguage/Wikidata:SPARQL query service. For some of its visualizations, it uses other tools.

Usage on Wikimedia sites[edit]

While Scholia uses data from Wikidata, it can itself be used across Wikimedia projects, e.g. by way of a template pointing from a Wikipedia or Wikimedia Commons page to a corresponding Scholia profile. A subset of such usage is tracked here.


Finn Årup Nielsen created the tool and encourages the Wikimedia community to engage with it.


Scholia's dependencies[edit]

Scholia profiles[edit]

Curation pages[edit]

Several of Scholia's aspects have associated pages that help curate gaps related to the profile in question. They can usually be accessed by adding /curation to the profile's URL.


Some of Scholia's aspects allow to compare several entities. They can usually be accessed by changing the aspect in the URL from singular to plural and adding the Wikidata identifiers after the slash, separated by commas. The current setup supports comparisons of up to about 5 entities.
