13:45 - 14:45 Keynote Talk: From Opacity to Clarity: Embracing Transparent and Accountable Fact Verification
Pepa Atanasova (University of Copenhagen)
Automating fact-checking processes is of paramount importance in the era of abundant online misinformation. Although substantial progress has been made in developing accurate systems, the focus must now shift towards ensuring transparency and accountability. The lack of understanding in the decision-making process of machine learning models, acting as black boxes, raises concerns about their reliability and trustworthiness. This invited talk will delve into the significance of explainability in automated fact checking. We will explore the state-of-the-art transparency methods that provide textual explanations for models' predictions, improving trust among stakeholders and enabling the identification of potential errors or biases. The talk will also present novel approaches to generate fluent, easy-to-read explanations with logically connected multi-chain arguments. By emphasizing the importance of explainability, this talk aims to shed light on the potential benefits of transparent fact-checking models. Attendees will gain insights into how such explainability systems can bolster the analysis of model outputs, enhance decision-making processes, and contribute to building a more informed and trustworthy online information ecosystem.

11:15 - 12:15 Keynote Talk: The User and the Algorithm: A Tug of War or Allies?
Judith Möller (University of Hamburg & Leibniz-Institute for Media Research | Hans-Bredow-Institut)
The relationship between users and algorithms in digital spaces remains a complex area of study. Dr. Judith Möller's research sheds light on how users interact with and influence their algorithmically curated information environments. Contrary to the perception that algorithms solely define content and user experience, evidence suggests that users play a more active role in determining their information spheres, if they want to. However, the real challenge lies in motivating users to recognize and harness the power they possess within these systems. Therefore, this talk will address the potential of nudges in these environments to guide users towards informed decisions. The aims of this keynote is to provide a balanced perspective on the intricate dynamics between users and algorithms in the digital age.
