wikipedia_citations — English Wikipedia citations of identified works (2020)

Description

A bipartite network of the articles of the English Wikipedia and the works (scholarly articles, books, ...) they cite, from the Wikipedia Citations dataset of H. Singh, R. West and G. Colavizza. The authors extracted all the citations made with citation templates (cite journal, cite book, cite news, citation, ... 35 templates in all) from the wikitext of the articles in the English Wikipedia dump of May 2020, 29.3 million citations in total, together with the identifiers given in them (DOI, PMID, PMC, ISBN, arXiv, JSTOR, OCLC, ...).

A directed edge from an article to a work is a citation. Only the citations that carry an identifier of the cited work can be linked to the same work cited elsewhere, so only these are included (3.8 million citations); the others (mostly of news and web pages, identified only by their title or URL) are left out. Each work is identified by the first identifier available among, in this order: DOI, PMID, PMC, arXiv, Bibcode, JSTOR, ISBN, OCLC, LCCN, Open Library, ASIN, MR, zbMATH, JFM, SSRN, OSTI, RFC, ISMN and Usenet id. DOIs are compared in lower case, and ISBNs as 13-digit numbers (ISBN-10s are converted, and hyphens removed). Citations with only an ISSN (which identifies a journal, not a work) are left out. A work cited with different identifiers in different articles (e.g. only a PMID in one, and a DOI in another) appears as several nodes. The candidate DOIs found by the authors for some citations without identifiers by searching Crossref are not used. The network is a multigraph, since an article may cite the same work several times.

The network has the following properties:

(Node) is_article: whether the node is a Wikipedia article (otherwise it is a cited work).
(Node) title: the title of the Wikipedia article, or of the cited work (as written in the first citation of it).
(Node) id_type (works): the type of the identifier of the work, e.g. DOI, PMID, ISBN.
(Node) id (works): the identifier of the work (normalized as described above).
(Node) identifiers (works): all the identifiers given in the first citation of the work, e.g. {PMID=20784713, PMC=2282302, DOI=10.1136/bmj.1.4286.261}.
(Edge) template: the citation template used, e.g. cite journal.
