The first Mediate workshop was held virtually on June 8th, 2020, as part of the International AAAI Conference on Web and Social Media (ICWSM). The main goal of the workshop was to bring together media practitioners and technologists to discuss new opportunities and obstacles that arise in the modern era of information diffusion. This year's theme was Social and News Media Misinformation, the various forms it can take, and the different ways one can approach it.

The contributed papers of the workshop were published in the Workshop Proceedings of ICWSM, and all the talks are publicly available online.

Call for Papers

Misinformation is regarded as a problem that has reached new heights in the current information sphere, partly due to the ease, the diversity of mediums, the reach, and the consequences of information dissemination.

We particularly encourage submissions tackling the current information flood surrounding COVID-19. We believe that this "infodemic" requires us to step-up all efforts to fight online misinformation, and research at this workshop can contribute to these efforts.

MEDIATE's topics of interest include, but are not limited to:

  • Political Misinformation
    • Traditional phenomena in political misinformation such as filter bubbles, echo chambers, and polarisation
    • Intentional or unintentional ''self-misinformation'', i.e., how well people consume information, whether it is authentic or fake
    • Analysis on how dire, measurable, or controllable these phenomena are and how they change over time
  • Scientific Misinformation
    • Studies on pseudo-scientific news that has deceived the public (e.g., the anti-vaccination movement or the coronavirus remedies quackery)
    • Discussions on journalists' trade-off between using appealing and accessible language, and accurately reporting research findings
    • Methodologies for effective communication of science to a non-specialized broad audience via news
  • Social Initiatives against Misinformation
    • Proposals to increase media literacy and/or redesign the news ecosystem with an enhanced role for some key players (e.g., regulators, educators, sociologists, scientists, etc.)
    • Media practitioners' perception of the shift from traditional journalism to computational journalism (e.g., an outline of the main acknowledged opportunities and caveats)
    • Personalisation, moderation of user engagement, and other concrete examples of how scientific innovation can impact the spread of misinformation
