Workshop on Reducing Online Misinformation through Credible Information Retrieval (ROMCIR 2026)

Session Information

Nowadays, we are all aware of the problems that can arise from coming into contact with dis- and mis-information that are propagated mainly through the Web, social media in particular, through different kinds of information disorder communication forms.

False news can, for example, guide public opinion in political and financial choices; false reviews can promote or, on the contrary, destroy economic activities based on malicious behaviors; unverified medical information can lead people to follow behaviors that can be harmful to their own health (and to that of society as a whole).

What we see unfolding right before our eyes is nothing less than Moore's Law applied to the distribution of mis-information: an exponential growth of available technology coupled with a rapid collapse of costs.

In this context, it becomes essential to guarantee to users access to credible information that does not distort their perception of reality. For this reason, in recent years, numerous approaches have been mainly proposed for the identification of false information, in different contexts, and for different purposes.

However, the problem is still of great interest with respect to many open issues, such as early detection of dis/misinformation, the retrieval of credible information, the development of solutions that can be understood by final users (explainable AI), the study of the problem in the health-related field, the relationship between security, privacy, and credibility in information access and dissemination.

In this scenario, the role of social computing is crucial to investigating such open issues, providing users with automatic but understandable tools to help them come into contact with genuine information.

There is an immediate need to seek workable solutions for the polluted information streams that are now characteristic of our modern, networked, and increasingly polarised world.

Reducing Online Misinformation through Credible Information Retrieval (ROMCIR 2026)

WorkshopsWorkshops 01:30 PM - 05:00 PM (Europe/Amsterdam) 2026/04/02 11:30:00 UTC - 2026/04/02 15:00:00 UTC
In the online digital ecosystem, we are surrounded by distinct forms of information pollution, posing significant threats to both individuals and society as a whole. Just think of the recent riots in England and Wales which were triggered by deliberate misinformation. Other instances of false news, for instance, wield power to sway public opinion on matters of politics and finance. Deceptive reviews can either bolster or tarnish the reputation of businesses, while unverified medical advice may steer people toward harmful health practices. In light of this challenging landscape, it has become imperative to ensure that users have access to both topically relevant and factually accurate information that does not warp their perception of reality, and there has been a surge of interest in various strategies to combat misinformation through different contexts and multiple tasks. The purpose of the ROMCIR Workshop, for some years now, is precisely that of engaging the Information Retrieval community to explore potential solutions that extend beyond conventional misinformation detection approaches. Key objectives include identifying subjective and objective factors associated with information credibility and truthfulness respectively, and integrating such factors as fundamental dimensions of relevance within Information Retrieval Systems (IRSs), achieving early detection of misinformation, and ensuring that the search results retrieved are not only truthful but also explainable to the users of IRSs. Moreover, it is essential to evaluate the role of generative models such as Language Models (LLMs) in inadvertently amplifying misinformation problems, and how they can be used to support IRSs, together with the contribution that the human-in-the-loop paradigm can have in this context.
