A new chapter in the history of ICTIR: Ten years ago, ICTIR 2015 was established under the ACM SIGIR umbrella. Given the evolving nature of the Information Retrieval field and the needs of the SIGIR community and the conference, ACM ICTIR, formerly known as the “ACM SIGIR International Conference on the Theory of Information Retrieval”, is renamed to ACM SIGIR International Conference on Innovative Concepts and Theories in Information Retrieval.
This new branding highlights and clarifies the focus of the conference for the authors, the reviewers, and the organizers. The conference aims to provide a forum for the presentation and discussion of research related to the foundational aspects of Information Retrieval (IR), including, for example, new or improved models of relevance, ranking, representation, information needs, and evaluation. The conference also welcomes interdisciplinary research that connects information retrieval with other research disciplines that are theoretically motivated. We use the definition of foundation used by ICTIR founders as a scientific result that others can build upon and use for their own research. While IR research traditionally relies heavily on rigorous experimentation, ICTIR does not see this as a must.
ICTIR 2025 will be held on July 18 in Padua, Italy and invites submissions with substantial and original research on innovative methodological contributions to the field of Information Retrieval. This includes original research on the theoretical aspects of Information Retrieval, topics from neighboring fields with a strong and clear connection to Information Retrieval, and novel approaches and methods for developing, improving, and evaluating models related to the field of Information Retrieval.
📢Additionally, ICTIR 2025 considers the following theme and especially welcomes research papers related to the following theme: “LLMs + IR, what could possibly go wrong?”
📢New to ICTIR, ICTIR 2025 accepts both regular and SIGIR Revise-and-Resubmit (SIGIR-RR) submissions.

Co-Located with ACM SIGIR 2025
ICTIR 2025 is co-located with SIGIR 2025. ICTIR 2025 is held one day after the entire SIGIR 2025 program. This means that there is no overlap with SIGIR 2025, thus attendance to ICTIR 2025 does not compete with any of the SIGIR tutorials, workshops or main program.
ICTIR 2025 takes place in the same venue as SIGIR 2025: the Padova Congress Center, see the following page for more information.
Registration details will be provided soon.
