Conference for Truth and Trust Online – 2020

Truth and Trust Online 2020 was hosted virtually on the 16th and 17th of October.


While trustworthy online spaces benefit everyone, untrustworthy content and behaviour can divide, confuse, and cause real harm.

The annual Conference for Truth and Trust Online is organised as a unique collaboration between practitioners, technologists, academics and platforms, to share, discuss, and collaborate on useful technical innovations and research in the space.

Our mission is to bring together all parties working toward improving the truthfulness and trustworthiness of online communications. TTO is an annual forum for academia, industry, non-profit organizations, and other stakeholders to discuss the problems facing (social) media platforms and technical solutions to understand and address them. Read more in our call for papers.

The second edition of the conference will be taking place virtually on October 16th and 17th 2020. Registration is essential!

How do we make online news systems trustworthy?

Trust in the news media continues to fall globally, according to a recent report by the Reuters Institute at Oxford, and the context of social media itself is a leading cause for concern when it comes to the spread of false or misleading information. Yet the desire for up-to-date reliable news remains strong especially as we navigate health and humanitarian crises.  A key component of this experience is shaped by recommendation systems and search algorithms, which also suffer limitations such as bias. 

What are the most pressing issues and can they be fixed? Join us we hear from a panel of journalists and technologists about the challenges related to credible news shared through algorithms at worldwide scale.

How do we address the ‘community’ in solutions for online public health?

In a global pandemic amidst unprecedented physical isolation, the need to understand health risks and mitigation strategies is critical. Given the public’s dependency of social media and online information, how do we reimagine and address this critical need via trust, truthful, and evidence-based information online? How do we bridge all the global information for very solitary lives? Join us as we hear from a panel of experts in public health and platform technologies share their perspectives.
