Wikidatatrust, a tool for visualizing who contributed to which Wikidata statement

I am a biophysicist (Q14906342) interested in integrating research (Q42240) workflows with the Internet (Q75) — particularly if they relate to medicine (Q11190), Biodiversity (Q47041) or open science (Q309823). My contributions here cover similar topics, with a focus on scholarly publications as sources for statements in Wikidata. My most recent affiliations are Institute for Globally Distributed Open Research and Education (Q55775817), Ronin Institute (Q27207785), Freie Universität Berlin (Q153006), Leibniz Institute of Freshwater Ecology and Inland Fisheries (Q1813732), Fraunhofer Institute for Biomedical Engineering (Q1167435) and University of Virginia (Q213439) — see my ORCID profile for details. I enjoy most of the interactions with the Wikidata community, which sometimes trigger wiki thanks.

For semi-automated or tool-assisted edits, I am experimenting with a separate account over at User:Research Bot.

Bugs to reportEdit

Italics in titles not recognized upon importEdit

See also this discussion and its on-wiki counterpart.

PhenotypeEdit

e.g. see version history of

Origin of the problemEdit

looks like the incorrect handling of the italics comes from Crossref, e.g. from https://api.crossref.org/v1/works/http://dx.doi.org/10.1271/bbb.57.628 for 20-Ketoreductase Activity of Chaetoglobosin A and Prochaetoglobosins in a Cell-free System of Chaetomium subaffine and the Isolation of New Chaetoglobosins (Q78436365)

Variants of the problemEdit

in Correction: Deciphering the Growth Behaviour of Mycobacterium africanum. (Q46502996), the title was missing the taxon name for a while, which can be traced back to Europe PMC

FlaggingEdit

See also Help:Ranking and Help:Deprecation and usage stats for deprecated rank as well as for preferred rank

ExamplesEdit

The problem may not be apparent from what is currently displayed here, so it is advisable to check the version history for the items in question.

No auto-relinking after merging of lexemes?Edit
