Hello all,
In this month’s showcase, we have two presentations on the importance and
value of Wikipedia outside of Wikipedia. In the first talk, Nick Vincent
will present results on the importance of Wikipedia for search engines in
which they looked how often and where Wikipedia links appeared in search
results of Google, Bing, DuckDuckGo, etc. In the second talk, Tiziano
Piccardi will present a recent study on the value of Wikipedia’s links to
external websites by quantifying the amount of traffic generated by those
links and analyzing for which types of articles Wikipedia acts as a
stepping stone to the intended destination.
Time/date: May 19, 16:30 UTC (9:30am PT/ 12:30pm ET/ 18:30pm CET)

Title: The Importance of Wikipedia to Search Engines and Other Systems
Abstract: A growing body of work has highlighted the important role that
Wikipedia’s volunteer-created content plays in helping search engines
achieve their core goal of addressing the information needs of hundreds of
millions of people. In this talk, I will discuss a recent study looking at
how often, and where, Wikipedia links appear in search engine results. In
this study, we found that Wikipedia links appeared prominently and
frequently in Google, Bing, and DuckDuckGo results, though less often for
searches from a mobile device. I will connect this study to past work
looking at the value of Wikipedia links to other online platforms, and to
ongoing discussions around Wikipedia's value as a training source for
modern AI.

Title: On the Value of Wikipedia as a Gateway to the Web
Abstract: By linking to external websites, Wikipedia can act as a gateway
to the Web. However, little is known about the amount of traffic generated
by Wikipedia's external links. We fill this gap in a detailed analysis of
usage logs gathered from Wikipedia users' client devices. We discovered
that in one month, English Wikipedia generated 43M clicks to external
websites, with the highest click-through rate on the official links listed
in the infoboxes. Our analysis highlights that the articles about
businesses, educational institutions, and websites show the highest
engagement, and for some content, Wikipedia act as a stepping stone to the
intended destination. We conclude our analysis by quantifying the
hypothetical economic value of the clicks received by external websites. We
estimate that the respective website owners would need to pay a total of
$7--13 million per month to obtain the same volume of traffic via sponsored
search. These findings shed light on Wikipedia's role not only as an
important source of information but also as a high-traffic gateway to the
broader Web ecosystem.
