Hi all, The next Research Showcase will be live-streamed next Wednesday, October 16, at 9:30 AM PDT/16:30 UTC. We’ll have two timely presentations from Fabrício Benevenuto and Francesca Spezzano about disinformation and how to counter it. YouTube stream: https://www.youtube.com/watch?v=KZ35weAVlIU As usual, you can join the conversation on IRC at #wikimedia-research. You can also watch our past research showcases here: https://www.mediawiki.org/wiki/Wikimedia_Research/Showcase 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.
