Proceedings of the 3rd Workshop on Reducing Online Misinformation through Credible Information Retrieval 2023 co-located with The 45th European Conference on Information Retrieval (ECIR 2023), Dublin, Ireland, April 2, 2023

The 2023 Workshop on Reducing Online Misinformation through Credible Information Retrieval (ROMCIR 2023) is at its Third Edition, as part of the Satellite Events of the 45th European Conference on Information Retrieval (ECIR 2023). ROMCIR aims at offering a discussion forum about access to truthful information and mitigation to the information disorder phenomenon, which characterizes our current online environment. This problem is very broad, as it concerns different information objects (e.g., Web pages, online accounts, social media posts, etc.) on different platforms, and different domains and purposes (e.g., detecting fake news, retrieving truthful health-related information, reducing propaganda and hate-speech, etc.). In this context, all those approaches that can serve, from different perspectives, to tackle the truthful information access problem, find their place. In particular, this year keynote speeches and articles have been presented discussing the problem of providing skills for people to identify the truthfulness of information, preventing access to health misinformation, and improving the evaluation processes of truthful information retrieval solutions
