The workshop invites contributions that explore media trust and journalistic authority using innovative methods grounded in the field of information retrieval. In today's platformized media ecosystem, the evaluation and monitoring of media trust and journalistic authority require novel approaches that consider the perspectives of citizens and end-users, as well as the mediating role of social media platforms. These platforms have significantly reshaped the way people access and engage with news, making them a crucial component in understanding contemporary media dynamics.

According to the Digital 2023 - Global Overview Report, 'finding information' remains the leading reason why individuals use the internet, closely followed by 'keeping up with news and current events.' Social media platforms such as Facebook, X (formerly Twitter), Instagram, and TikTok have transitioned from simple social interaction spaces to essential channels for news dissemination. Globally, social media has become one of the most popular sources of news, outpacing traditional mediums like radio, print publications, blogs, and even word-of-mouth. This impact is particularly evident among younger demographics. Generation Z and Millennials, in particular, exhibit a strong preference for consuming news on social platforms, gravitating towards visually engaging and interactive formats like videos and infographics, which are prevalent on platforms like TikTok and Instagram. In response, traditional news outlets have been compelled to adapt, integrating formats that are more suitable for social media into their content distribution strategies.

In this evolving landscape, Artificial Intelligence (AI) plays an increasingly influential role in how news is curated and consumed on social media. AI-driven algorithms analyze vast amounts of user data to deliver personalized news feeds, tailoring content based on past user behavior, search history, and social connections. While this level of personalization allows for a highly customized news experience, it raises concerns about the formation of echo chambers. These echo chambers can reinforce users' existing beliefs by repeatedly exposing them to similar viewpoints, limiting exposure to diverse perspectives and potentially contributing to polarization.

In light of these trends, the workshop seeks to foster discussions and insights into innovative strategies for addressing the challenges and opportunities presented by AI-driven news consumption, media trust, and the evolving authority of journalism in the digital age.
