Nowadays, advances in computer engineering made it possible that humans may interact with the machines in their natural language either in the written or the spoken manner. At the same time, the amount of (textual) data available in big data bases as well as the world wide web is growing in a rapid manner. Both developments setup new challenges for the development of innovative algorithms to recognise speech, to categorise and classify not only textual information in short times as well as to extract knowledge and wisdom from a huge pile of raw, unevaluated data.

At the situation, 2025 9th International Conference on Natural Language Processing and Information Retrieval (NLPIR 2025) will bring together researchers, which devoted their work to progress in the above described timely tasks. It will be held in Kyushu University, Fukuoka, Japan during December 14-16, 2025.

Submission Guidelines

Requirements Official language is English in paper writing and presenting. Manuscripts should be at least 8 pages (Single column). Additional page (if the paper exceeds 10 pages) is possible but will be charged for 50 USD per page.
