Query: Reliability in Time: Evaluating the Web Sources of Information on
  COVID-19 in Wikipedia across Various Language Editions from the Beginning of
  the Pandemic   There are over a billion websites on the Internet that can potentially serve
as sources of information on various topics. One of the most popular examples
of such an online source is Wikipedia. This public knowledge base is co-edited
by millions of users from all over the world. Information in each language
version of Wikipedia can be created and edited independently. Therefore, we can
observe certain inconsistencies in the statements and facts described therein -
depending on language and topic. In accordance with the Wikipedia content
authoring guidelines, information in Wikipedia articles should be based on
reliable, published sources. So, based on data from such a collaboratively
edited encyclopedia, we should also be able to find important sources on
specific topics. This effect can be potentially useful for people and
organizations.
  The reliability of a source in Wikipedia articles depends on the context. So
the same source (website) may have various degrees of reliability in Wikipedia
depending on topic and language version. Moreover, reliability of the same
source can change over the time. The purpose of this study is to identify
reliable sources on a specific topic - the COVID-19 pandemic. Such an analysis
was carried out on real data from Wikipedia within selected language versions
and within a selected time period.
