The Fifteenth NTCIR conference (NTCIR-15) would like to welcome all of you who are interested in and/or working on information access research. This sesquiannual event was first held in 1999, and has grown steadily ever since. About 160 people from 15 different countries attended NTCIR-14/EVIA 2019 and we are hoping that the event will be even more successful this time. NTCIR covers diverse information access tasks including, but not limited to, information retrieval, question answering, text summarisation and text mining, with an emphasis on East Asian languages and English.

At the NTCIR-15 conference, we will hear exciting reports from the following tasks:

- DialEval: Dialogue Evaluation
- FinNum: Numeral Attachment in Financial Tweets
- QALab-PoliInfo: (Question Answering Lab for Political Information)
- SHINRA2020-ML: (SHINRA 2020 Multi-lingual)
- WWW: (We Want Web)
- Data Search: (Data Search)
- MART: (Micro Activity Retrieval Task)

While the NTCIR conference is a venue for task participants and organisers to discuss the official task results, open problems and future task designs, our door is open even to those who did not participate in any of the NTCIR-15 tasks. For the previous Conference, among them about half were researchers participated in the "task(s)" set by NTCIR, and others contributed to fruitful discussion.

We look forward to seeing you all at NII in December!
