Please prepare the forms carefully. Please download the relevant form(s), make two sets of original double-sided copies, sign, and send (by postal mail or courier) to the NTCIR Project Office at the address specified below.

(3) WORKSHOP AIMS: [further information]

The NTCIR Workshop is a series of evaluation workshops designed to enhance research in information access technologies including information retrieval, summarization, extraction, question answering, etc. It was co-sponsored by Japan Society for Promotion of Science (JSPS) as part of JSPS "Research for Future" Program" and National Center for Science Information Systems (NACSIS) since 1997, by JSPS and the Research Center for Information Resources at the National Institute of Informatics (RCIR/NII,) in FY 2000, by RCIR/NII in FY2001, and by RCIR/NII and MEXT grand-in aid in and after FY2002.

The aims are;

  1. to encourage research in information access technologies by providing large-scale data collections reusable for experiments and a common evaluation infrastructure allowing cross-system comparisons
  2. to provide a forum for research groups interested in cross-system comparison and exchanging research ideas in an informal atmosphere
  3. to investigate evaluation methods of IR and text processing techniques and methods for constructing a large-scale data set reusable for experiments.

This is an opportunity to compare the wide variety of approaches and strategies of each participant, to exchange research ideas, and to learn each other's experience on the same data set and the same evaluation infrastructure. We do hope each of you will enjoy and utilize this opportunity to improve the researches in information access technologies. Any suggestions, advises, leads, etc., are always welcome!

If you have any question or problems, please do not hesitate to contact us.
