Presentation Instructions

ICTIR 2021 will be an online live conference held jointly with the SIGIR 2021 conference. We are committed to promoting an interactive dense program that is convenient to attend for the people of our community in all time zones. ICTIR this year is a 24-hour program with a 12-hour gap between the two parts of the program. This is to ensure that each paper is presented live at a reasonable time for its authors. The schedule of the talks is available here.

One presenter for each paper is expected to give a live talk and be available for discussion at a poster session. The live talks will be held on Zoom, and the posters will be presented using a virtual space at The links to the Zoom sessions and space will be available on a platform called Underline.

All presenters are required to upload a pre-recorded video. If an unexpected technical problem arises during the live session, the video will be presented. Instructions on how to submit the video will be sent to the authors via a separate email.

Paper Presentation

While we do not have separate long/short paper tracks this year, we allocate more presentation time to longer papers (as publicized in CFPs).

Submissions with 7.5 pages or more (excluding references): 22 minutes talk + 3 minutes QA
Submissions with less than 7.5 pages (excluding references): 12 minutes talk + 3 minutes QA

An email will be sent to each author to confirm the presentation time.

Poster Presentation

Two poster sessions are scheduled in the conference program, where participants can talk to the presenters of the papers and discuss their work. All posters will be available during the 24 hours of the ICTIR program at, and authors are encouraged to attend both poster sessions (if possible based on their time zones). It is, however, expected that one author for each paper presents the paper at its assigned poster session.

General instructions on using the Underline platform and environment are available at the SIGIR poster presenter training video.

Final remark

We are aware that the presentation times may not be convenient for some of you. Although we tried to adjust the program to authors’ timezones, there is really no solution that works for everyone. We appreciate your understanding and cooperation.
