Add A Fact is a temporary experimental tool created by the Wikimedia Foundation's Future Audience team to learn how and if we can support making it possible to contribute productively to Wikipedia from outside of Wikipedia, and if guidance to the contributor from a large language model (LLM) could be useful in this process. The idea was developed and workshopped with Wikipedians at WikiConference North America 2023, demoed and tested with Wikipedia community members as part of our team’s regular monthly community calls.

Add A Fact is available for the Google Chrome and Mozilla Firefox browsers and can be used by any logged in, autoconfirmed English Wikipedia user. We welcome your feedback on the talk page of this page, or via the Feedback tool in the browser extension.

Chernoff faces, invented by Herman Chernoff in 1973, display multivariate data in the shape of a human face. The individual parts, such as eyes, ears, mouth and nose represent values of the variables by their shape, size, placement and orientation. The idea behind using faces is that humans easily recognize faces and notice small changes without difficulty. Chernoff faces handle each variable differently. Because the features of the faces vary in perceived importance, the way in which variables are mapped to the features should be carefully chosen (e.g. eye size and eyebrow-slant have been found to carry significant weight).

The cantu a tenòre (Sardinian: su tenòre, su cuncòrdu, su cuntràttu, su cussèrtu, s'agorropamèntu, su cantu a pròa; Italian: canto a tenore) is a style of polyphonic folk singing characteristic of the island of Sardinia (Italy's second largest island), particularly the region of Barbagia, though some other Sardinian sub-regions bear examples of such tradition.

In 2005, UNESCO proclaimed the cantu a tenore to be an example of intangible cultural heritage.
