Wikidata:WikiCite/Citation Typing Ontology

This page gives some information about how citations (using Citation Typing Ontology (Q44955364)) can be annotated with their citation intention and what Wikidata holds currently.

Each citing resources (journal article, data sets, software, etc) uses cites work (P2860). The CiTO annotation is added as a qualifier using has goal (P3712). The value of that qualifier has a value that is instance of citation intent (Q96471816), e.g. cites as authority (Q96479983) or one of these.

For example, the item Q102371658 has the following statement:

• v
• t
• e

cites work	Crystal Structure of the SARS-CoV-2 Non-structural Protein 9, Nsp9 edit series ordinal 40 has goal cites as authority 0 references add reference
		add value

Currently, mainly two sources are used to add data:

1. journals and preprint servers that have explicit CiTO annotations
2. other sources

The other sources can be manually added, but also results from a publicly released dataset, like I did with CiteULike CiTO annotations (Q115470140).

• Journal of Cheminformatics (Q6294930) (multiple articles, see https://www.biomedcentral.com/collections/cito for the pilot, but several papers after the pilot were published)
• Journal of Biomedical Semantics (Q6294854) (one article)

• ChemRxiv (Q50012382) (e.g. https://chemrxiv.org/engage/chemrxiv/article-details/62569956742e9f1b495b88a2)
• BioHackrXiv (Q115450084) (e.g. https://biohackrxiv.org/7f95d/ aka An ETL pipeline to construct the Intrinsically Disordered Proteins Knowledge Graph (IDP-KG) using Bioschemas JSON-LD data dumps (Q115449286))

• CiteULike CiTO annotations (Q115470140)
• Inputs and results of "A quantitative and qualitative citation analysis to retracted articles in the humanities domain" (Q117357537)

It is now also possible to define citation annotations (even signed) as nanopublications. See this blogpost.
