Wikidata:WikiProject Identifying Knowledge Gaps

From Wikidata
Jump to navigation Jump to search

This Wikiproject is for using Wikidata to identify gaps in Wikipedias and other Wikimedia projects based on both data from Wikidata, other Wikipedias and from outside sources. Using Wikidata to do this provides both clear ways of articulating gaps, and you can use computation on top of that knowledge or to identify other problems and make them visible to other contributors. For example, on projects like the meta:WikiPedia Cultural Diversity Observatory or Project GLOW, outside datasets are generated by various methodologies to identify potential topics of interest to participants.

However, data modeling for surfacing this kind of material, using these different properties, like on focus list of Wikimedia project (P5008), and practices for leveraging authorities don't have clear strategies for identifying thing like language of origin, methodologies used to generate lists, or identifying target languages for filling these gaps. This WikiProject is for discussing the data modeling and other needs for gap identification.

Specific sub projects[edit]

Each of these specific sub projects are for discussing how to leverage outside methodologies to surface missing topics on Wikidata:


The property on focus list of Wikimedia project (P5008) can be used to document a focus group within Wikimedia projects that doesn't have a clear identifier or property based

The following qualifiers have been used with P5008:

Title ID Data type Description Examples Inverse
point in timeP585Point in timepoint in time: time and date something took place, existed or a statement was true2012 United States presidential election <point in time> -
locationP276Itemphysical location: location of the object, structure or event. In the case of an administrative entity as containing item use P131. For statistical entities use P8138. In the case of a geographic entity use P706. Use P7153 for locations associated with the object.Mona Lisa <location> Louvre Museum-
main subjectP921Itemtopic, matter and subject: primary topic of a work (see also P180: depicts)Marina <main subject> Rocco Granata-

Using authorities[edit]

Ingesting sets of identifiers from other authorities has been a common approach for identifying gaps in Wikimedia projects. For coordinating authority work, see Wikidata:WikiProject Authority control.

Here we will document the use of tactics like Authorities and Mix-n-match to strengthen gap identification.
