SoHuman 2012

1st International Workshop on Social Media for Human Computation
September 3, 2012, Amsterdam, co-located with IEEE Social Computing 2012

************************** 2nd CALL FOR PAPERS *****************************


Human computation is a paradigm considering humans as distributed 
task-solvers as a part of intelligent computational systems. It leverages 
human reasoning to solve complex tasks that are easy for humans but 
difficult for purely computational approaches. Effective realizations of 
this paradigm typically require participation of a large number of 
distributed users over the Internet. Though rarely explicitly addressed as 
such, social media and related technologies often provide the enabling 
methods and technologies for realization of such models.  Examples of human 
computation applications include crowdsourcing marketplaces (e. g. Amazon 
Mechanical Turk), crowdsourcing service providers (e.g. Microtask, 
CrowdFlower) or games with a purpose. While the former provide coordination 
services for workers performing tasks for financial awards the latter 
motivate user participation through game-based scenarios.

The workshop invites researchers and practitioners from research and 
industry to discuss the challenges and opportunities of applying social 
media to developing and implementing new kinds of human computation systems 
and applications. We are interested in contributions that interrelate 
experiences from social media and human computation research.

This involves questions such as:
* How can we design effective incentive systems for large-scale 
* 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 collaborative systems 
and social networks lead to novel classes of human computation tasks and 

We particularly solicit contributions emphasizing social media and human 
computation as it is used in practice (i.e. in terms of specific problems 
and use cases) in diverse domains and types of applications, such as:
- multimedia search, 
- enterprise and medical applications, 
- cultural heritage, 
- social data analysis or 
- open science.
This also includes open social networks involving different user groups in 
heterogeneous settings (e. g., end-users, small and medium-sized 
businesses, scientists, policy makers, citizens). In this way, the workshop 
shall contribute to identifying best-practices and opportunities for new 
approaches to designing and implementing human computation systems.

Topics of interest include (but are not limited to):
- Social media in human computation systems
- Social incentive models for human computation
- Social-network analysis for human computation
- Applications of social media visualization to human computation
- Social coordination for human computation
- Social search and human computation
- Trust models and reputation systems for human computation
- Expertise-inference techniques and their application to task routing
- Quality assurance in distributed human intelligence tasks
- Social sensing in human computation
- Domain-specific challenges and use cases in social media for human
