Welcome to the Virtual ICWSM 2021

Pre-recorded talks are available to view at your convenience on this website. During the live sessions, presentations have been assigned a one-hour slot during which we ask at least one author to be available to interact synchronously with participants on gather town. (Think of it like a virtual conference poster session where authors can interact with participants).
There are two ways of enjoying the conference this year:
ICWSM Lite - The MiniConf and Slack experience. Similar to last year’s ICWSM, participants can choose a largely solo journey through the talks and events in ICWSM but still meet up with others through Slack ( and the single-track events. Limited opportunities to interact with paper authors, but you can always invite them to catch up on Slack.
ICWSM Deluxe - The Gathertown, MiniConf, and Slack experience. Enrich your conference experience by hanging out in a custom-designed green space, much like your favorite spot on campus. Walk to your next session with your friends. Ask questions of the authors of the papers you really dig. Bump into the keynote speakers on your way to the next session. Hang out with the organising committee and ask all your burning questions. And when the sessions are over, unwind with new friends over a game of scribbl.

You can find the times for all the live sessions using the Schedule, where you can choose your timezone and find live sessions that work for you.
