The 31th China Conference on Information Retrieval

The 31st China Conference on Information Retrieval (CCIR 2025) is the primary domestic Chinese forum for academic and industrial research on information retrieval, search technologies, and related fields. The conference covers topics such as document ranking and relevance, question answering, knowledge-based search, neural retrieval models, recommendation systems, multilingual retrieval, and evaluation methodologies. As the volume of digital information continues to surge, effective retrieval systems have become foundational infrastructure for virtually every online service.

CCIR 2025 brings together researchers from universities, technology companies, and government research institutes who are advancing the theory and practice of information access. The conference is particularly valuable for students and early-career researchers in China who wish to publish and receive feedback within the Chinese research community while engaging with internationally relevant problems. Industrial participants gain exposure to the latest academic advances that can inform next-generation search and recommendation products.
