This month's presentations:

Elections Without Fake: Deploying Real Systems to Counter Misinformation
Campaigns

By Fabrício Benevenuto, Computer Science Department, Universidade Federal
de Minas Gerais (UFMG), Brazil

The political debate and electoral dispute in the online space during the
2018 Brazilian elections were marked by an information war. In order to
mitigate the misinformation problem, we created the project Elections
Without Fake <http://www.eleicoes-sem-fake.dcc.ufmg.br/> and developed a
few technological solutions able to reduce the abuse of misinformation
campaigns in the online space. Particularly, we created a system to monitor
public groups in WhatsApp and a system to monitor ads in Facebook. Our
systems showed to be fundamental for fact-checking and investigative
journalism, and are currently being used by over 150 journalists with
editorial lines and various fact-checking agencies.


Protecting Wikipedia from Disinformation: Detecting Malicious Editors and
Pages to Protect

By Francesca Spezzano, Computer Science Department, Boise State University

Wikipedia is based on the idea that anyone can make edits in order to
create reliable and crowd-sourced content. Yet with the cover of internet
anonymity, some users make changes to the online encyclopedia that do not
align with Wikipedia’s intended uses. In this talk, we present different
forms of disinformation on Wikipedia including vandalism and spam and
introduce to the mechanism that Wikipedia implements to protects its
integrity such as blocking malicious editors and page protection. Next, we
provide an overview of effective algorithms based on the user editing
behavior we have developed to detect malicious editors and pages to protect
across multiple languages.
