SoHuman2012 @IEEE Social Computing,Amsterdam, Sept 3, 2012
2. Goals of the workshop
Explore challenges and opportunities of applying social media
to designing human computation systems and applications
Discuss practical challenges and experiences with applications of
social media to human computation
Can we identify specific problem classes / use cases particularly
suited for new kinds of applications?
Enrich the technology-driven perspective strongly present in AI
and multimedia retrieval with a user-centered view
Stimulate the discussion on best-practices in this still young and
quickly growing field
3. Theme
Human Computation
Human users as task-solvers within
computational systems
Solving complex tasks that are easy for
humans but difficult for purely
computational approaches
Requires large numbers of participants
financial rewards, fun…
Social Media
Support online social interaction,
information exchange, coordination and
collective action
Can provide enabling methods and
technologies for human computation
4. Theme
Human Computation vs. Crowdsourcing
“Whereas human computation replaces
computers with humans, crowdsourcing
replaces traditional human workers with
members of the public.”
(Quinn & Bederson, 2011)
Human Computation vs. Social Media
“…social computing facilitates relatively
natural human behavior that happens to be
mediated by technology, whereas participation
in a human computation is directed primarily Quinn, A.J. & Bederson, B.B. (2011).

by the human computation system.” Taxonomy of a Growing Field, Proc. of
(ibid) CHI 2011
5. Approach
The need to interrelate social media research and human
computation is reflected in questions such as:
How can we design effective incentive systems for large-scale
participation?
How do we design tasks at different levels of complexity that can
still be solved reliably by individual contributions?
How can we use social media techniques for new models of
coordination (e.g. social network analysis for task-routing)?
How can lessons from distributed problem-solving in social
networks and collaborative systems lead to novel classes of
human computation tasks and applications?

12. Panel Discussion
Do we really need
social media for
crowdsourcing?
13. Questions
• Do we really need social media for crowdsourcing?
• Do we understand all dimensions: Motivation,
Quality control, Aggregation, Human Skill (expert,
not expert), Process order (how to hybidize?)
• How do we enrich the technology-driven
perspective with a user-centered view?
• How do we move beyond the “mechanical” aspect
of crowdsourcing to make use of a full range of
human perspectives and abilities?
• How do we "invent" new applications for
crowdsourcing?
• What are the major risks moving forward?
