The third MEDIATE workshop will be held on June 6, as part of the International AAAI Conference on Web and Social Media (ICWSM). The main goal of the workshop is 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 is: Misinformation: new directions in automation, real-world applications, and interventions. You can also check the program and recorded talks of the 2020 and 2021 editions of MEDIATE.

Philip Resnik Professor, Linguistics and UMIACS, University of Maryland
Why Do Misinformation Spreaders Also Share Information from Reliable Sources? The Role of Fake-News Narratives

A great deal of attention is paid to the spread of false/mis-/dis- information in media. But misinformation spreaders also share articles from reputable sources, sometimes including news outlets to which they're ideologically opposed. Why? We argue that understanding the misinformation landscape isn't just about factual truthfulness, it's about understanding the way that people's prior conceptions influence their perceptions. I'll describe work in which we've constructed a dataset to look at the sharing behavior of misinformation spreaders, and analysis suggesting that sharing true information can be connected with the way that information fits in with existing narratives from fake-news sources.

Heidi J Larson Professor, London School of Hygiene & Tropical Medicine
How Vaccine Rumours Start and Why They Don't Go Away

The vaccine enterprise has failed to keep pace with the changing global dynamics, and engage the alternative voices much earlier, partly because it didn't believe that what is happening now could ever happen. And there is still denial among some. Resistance to vaccines is a growing problem threatening global health. Prof Larson will discuss some of the roots of this resistance, consider the new challenges in the face of our hyper-connected media landscape and propose ways to move forward.

Call for Papers

Topics of interest include, but are not limited to:

  • New directions in verification automation: novel automated and human-in-the-loop methods for rumour detection/verification, fact-checking, stance classification and novel relevant tasks. Submitted papers should describe how their advantages would lead to being adopted in practice by journalists and the public, e.g. improved generalisability, ability to provide explanations, reduced bias, etc.
  • Real-world applications of automated methods: success stories (e.g., trending news/events detection), challenges (e.g., misinformation detection), partial solutions to known challenges (e.g., interpretable models).
  • Interventions: effective interventions to prevent the spread of false claims, automated and semi-automated content moderation, interdisciplinary discussions on digital governance and democracy.

We invite submissions of technical papers and talk proposals:

  • Technical papers must be up to 4 pages (short papers) or up to 10 pages (long papers). Technical papers must contain novel, previously-unpublished material related to the topics of the workshop. Accepted papers will be presented orally and will appear in the workshop proceedings.
  • Talk proposals must be up to 2 pages describing the content of a short talk (the actual length will be determined based on program constraints).

Papers must adhere to the ICWSM guidelines and be submitted through EasyChair. You can contact the organizers (details below) for questions related to the submission or participation.
