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.

The aims are;

1. to encourage research in information access technologies by providing large-scale infrastructure of research and evaluation.
2. to provide a forum for research groups interested in evaluation and exchanging research ideas in an informal atmosphere
3. to investigate evaluation methods and metrics of information retrieval and access technologies.

The main interest of us is "Speed the research in labs to real world". For this purpose, NTCIR provides the infrastructure of the research and evaluation. 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. To do so, each participating group takes responsibility to report the experimental results carefully in details with sufficient analysis to depict why and how the proposed method worked well or not, and contribute the forum to learn each other from each others experience. Module-based examination is also important to show how and why. 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 questions or problems, please do not hesitate to contact NTCIR-9 General Co-Chairs and Evaluation Co-chairs at ntc9-chairs.
