The Mushroom Challenge


Disinformation, propaganda and fake news poison our society. One of the most commonly used means for the spread of disinformation is the use of what we call mushroom websites, anonymous websites used for “seeding” disinformation and propaganda, and consequently generating buzz & fuss through social media amplification.


You will be challenged to build tools or a solution for detection of mushroom websites through the automatic calculation of credibility scores, based on transparent and objective criteria.


Sensika will suggest and disseminate formal criteria for scoring the credibility and trustworthiness of news websites, along with rich datasets of news websites content, links and statistics.


This November, we invite you to come mushroom hunting, together with us and some of the most prominent experts in the field of countering disinformation.


Let’s join forces in detecting and fighting mushroom sources and create algorithms to automate the process at scale. Collective work between developers, fact checker and journalists is highly encouraged.

Let’s go mushroom hunting, don’t miss it!
