Report on the 4th Workshop on Reducing Online Misinformation through Credible Information Retrieval (ROMCIR 2024) at ECIR 2024

Abstract

The 4th Workshop on Reducing Online Misinformation through Credible Information Retrieval (ROMCIR 2024) was part of the Satellite Events of the 46th European Conference on Information Retrieval (ECIR 2024). ROMCIR served as a platform for discussions on accessing accurate information and addressing the issue of information disorder prevalent in the online landscape at that time. In general, the challenge is multifaceted, encompassing various types of information sources (e.g., websites, social media posts, ...) across different platforms and domains (e.g., fake news detection, health-related information retrieval, propaganda reduction). Additionally, in this edition, the critical need to assess the impact of generative models like Large Language Models (LLMs) on inadvertently amplifying misinformation and explore their potential role in supporting Information Retrieval Systems (IRSs) began to emerge. In this context, diverse approaches to the problem of access to truthful information found their place. Keynote speech and articles in this year's workshop mainly focused on themes such as health misinformation, multimedia and multimodal fact-checking, and information filtering to combat misinformation.
