  The rise of Internet has made it a major source of information.
Unfortunately, not all information online is true, and thus a number of
fact-checking initiatives have been launched, both manual and automatic, to
deal with the problem. Here, we present our contribution in this regard:
\emph{WhatTheWikiFact}, a system for automatic claim verification using
Wikipedia. The system can predict the veracity of an input claim, and it
further shows the evidence it has retrieved as part of the verification
process. It shows confidence scores and a list of relevant Wikipedia articles,
together with detailed information about each article, including the phrase
used to retrieve it, the most relevant sentences extracted from it and their
stance with respect to the input claim, as well as the associated
probabilities. The system supports several languages: Bulgarian, English, and
Russian.
