The Industry Day of CIKM ’26 will be held on 7th November 2026 in Rome, Italy. We call for technical talks that cover how topics of interest relevant to the broader CIKM community (including but not limited to knowledge management, information retrieval, efficient data processing, large language models, evaluation, recommender systems, data mining, and others found in the CIKM ‘26 Call for Papers) are used in an industrial setting. Example topics include how AI is put to use in practical scenarios, how user behavior can be observed and interpreted, how to improve systems in practice, how industrial pipelines can be optimized, how to address cold start issues, or how scale is a challenge in more ways than the academic or the obvious. We encourage talk proposals from small companies, such as startups or spin-offs from university projects, as well as larger companies.
