GOALS OF THE WORKSHOP

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
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 collaborative systems
and social networks lead to novel classes of human computation tasks and
applications?

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
computation
