Wikidata:ScienceSource project/Focus list, Coronavirus

From Wikidata
Jump to navigation Jump to search

Using on focus list of Wikimedia project (P5008) with a qualifier, additions of article items related to COVID-19 (Q84263196) are now being made to the ScienceSource focus list, such as The Incubation Period of Coronavirus Disease 2019 (COVID-19) From Publicly Reported Confirmed Cases: Estimation and Application (Q87647368).

As of April 2020, the idea is to tag article items for articles used as references in Wikipedia articles about Covid-19. The initial purpose is just to improve the article items by adding statements, which can be of a number of kinds. There is also scope for improving the items about the journals in which the articles are published; and the items about the publishers of the journals.

The pandemic means that Wikidata has to deal with a great deal of biomedical literature about coronavirus topics. Newly-created article items may well be sparse, and missing even basic identifiers. Material at PubMed will be updated over time, so an initial creation cannot be very full, and there is reason to go back later. The way citations link articles obviously evolves over time. The focus list is a rather simple device to enable some tracking, in a changing situation.

At the main WikiProject[edit]

Wikidata:WikiProject COVID-19 has its own focus list, and you can read it with this query: 

#Focus list of the Wikidata WikiProject COVID-19
SELECT ?item ?itemLabel
  WHERE {?item wdt:P5008 wd:Q87748614.   
         SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }       
         }

For the context see Wikidata:WikiProject COVID-19/Focus list.

Missing articles[edit]

Checking Wikipedia articles related to coronavirus is a way to find cited articles that do not yet have Wikidata items. Currently these include from w:Coronavirus disease 2019:

  • Clinical Characteristics of SARS-CoV-2 Infected Pneumonia with Diarrhea, DOI 10.2139/ssrn.3546120
  • Smell and taste dysfunction in patients with COVID-19, DOI 10.1016/S1473-3099(20)30293-0, PMC 7159875
  • New SARS-like virus in China triggers alarm DOI 10.1126/science.367.6475.234, PMID 31949058

Viewing the list[edit]

This simplified query shows the focus list in reverse chronological order: 

SELECT ?item ?itemLabel ?date
  WHERE {?item wdt:P31 wd:Q13442814;
               wdt:P5008 wd:Q55439927;
               wdt:P577 ?date.
         
         SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }       
                               
         }

ORDER BY DESC(?date)

LIMIT 25

This version brings up the main subject (P921) statements: 

#Display of focus list papers from 2020, with subjects where they have been added.
SELECT ?item ?itemLabel ?date ?subjectLabel
  WHERE {?item wdt:P5008 wd:Q55439927;
               wdt:P577 ?date.
         OPTIONAL {?item wdt:P921 ?subject.}
         FILTER(year(?date) >= 2020)
          
         SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
                               
         }

ORDER BY DESC(?date)

Relevant types of statement[edit]

It is also quite possible that clinical trial (Q30612) items could usefully be brought in: not quite so obvious how.
