Task Participation

NTCIR is a periodical event held once per one and half years, which aims to promote research on information access technologies by forming a community and test beds incorporated by many research groups for experiments. The twelfth NTCIR, NTCIR-12, now calls for task participation of anyone interested in research on information access technologies and their evaluation, such as retrieval from a large amount of document collections, question answering and natural language processing. We welcome students, young researchers, professors who supervise (many) students, researchers working for a company, and anyone who is interested in informatics.

The registration for NTCIR-12 Task Participation has just started.
