I am happy to announce that the Fourth Human Computation Workshop (HCOMP 2012), will be organized this year together with the AAAI conference, on July 22 or 23. The conference is in Toronto.
The deadline for submitting a paper is March 30, 2012. You can submit either a "long" 6-page paper, or a "short" 2-page poster submission.
You can see the official web site or check the detailed Call for Papers at http://www.humancomputation.com/.
Last year, we had a big room for the workshop, which was jam-packed, with more than 100 people at the room at some point, and the program was full of excellent papers. So, if you have ideas about human computation, crowdsourcing, or on merging human and machine intelligence, you want to send a paper at HCOMP!
