********************* 2nd CALL FOR PAPERS *********************
SoHuman 2013 – 2nd International Workshop on Social Media
for Crowdsourcing and Human Computation, May 1, 2013, Paris

at ACM Web Science 2013
collocated with ACM HyperText'13 & ACM CHI'13 & ACM ECRC'13

Submission deadline: March 20, 2013
********************* 2nd CALL FOR PAPERS *********************

This workshop invites researchers and practitioners from different
disciplines to explore the challenges and opportunities of applying
social media to designing novel applications of collective intel-
ligence, with a special focus on crowdsourcing and human computation.

We are particularly interested in contributions that consider
crowdsourcing and human computation in the broader context:
as specific instantiations of collective intelligence and social
computing on the web. How can the experience gained from the design
of crowdsourcing applications inform the development of new
approaches to collective intelligence? And vice versa: what
lessons from the broader domain of collective intelligence
can inform the design of new kinds of systems for crowdsourcing
and human computation?

Both crowdsourcing and human computation consider humans as
distributed task-solvers, leveraging human reasoning to solve complex
tasks that are easy for individuals but difficult for purely
computational approaches (human computation) or for traditional
organizational work arrangements (crowdsourcing). Though rarely  
addressed as such, social media and related technologies often provide
the enabling methods and technologies for the realization of such  
Examples include crowdsourcing marketplaces (e.g. Amazon Mechanical
Turk), crowdsourcingservice providers (e.g. Microtask, CrowdFlower) or
games with a purpose. While centralized platforms are also at the core
of “traditional” approaches to collective intelligence (e.g. Wikipedia),
attention is increasingly turning to harnessing existing social
platforms (e.g. Facebook, Twitter) that already gather huge numbers
of users into webs of social relationships.

Such Social Clouds pose both chances and challenges for new kinds
of approaches to crowdsourcing and human computation in particular and
to collective intelligence in general. On one hand, the intricate
social relationships allow the development of new kinds of task routing
mechanisms (e.g. identifying the best or most trusted participants for
a specific task). Incentive structures are intrinsically social and
tend to reflect community-like phenomena (e.g. the reputation economy),
thus differing strongly from single-user approaches in classical
crowdsourcing. This is already leading to early experiments such as
expert-based crowdsourcing or solutions for task-injection across
distributed social platforms. On the other hand, the design of such
socially distributed computing structures relates the fields of
crowdsourcing and human computation to the lessons from a broader
class of collective intelligence platforms and applications.

The need to interrelate these fields is reflected in questions such as:
•	How can we design effective incentive systems for large-scale
	participation of human users in structured collective
	intelligence systems?
•	How do we design tasks at different levels of complexity that can be
	solved reliably through a composition of individual contributions?
•	How can we use intricate webs of social relationships of existing
	social platforms for new models of coordination in distributed
•	How can distributed social media enable the design of new classes
	of crowdsourcing applications (e.g. using social network analysis
	for new ways of task-routing)?
•	How can the comparison of lessons from distributed problem-solving
	in human computation and community-based approaches lead to novel
	classes of collective intelligence applications?

We are especially interested in applications and investigations in a
range of domains such as collective action and social deliberation,
multimedia search and exploration, enterprise and medical applications,
cultural heritage, social data analysis or citizen science.

Topics include (but are not limited to):
-	Social media in collective intelligence systems
-	Use cases and applications of social media to crowdsourcing and
	human computation
-	Social incentive models for crowdsourcing and human computation
-       HCI issues in crowdsourcing and human computation
-	Social-network analysis for crowdsourcing and human computation
-	Applications of social media visualization to collective
	intelligence applications
-	Social coordination in crowdsourcing and human computation
-	Social search and human computation
-	Trust models for collective intelligence and crowdsourcing
-	Semantic modeling in crowdsourcing and human computation
-	Expert-based crowdsourcing
-	Influence metering and social trust models
-	Expertise-inference techniques and their application
	to task routing
-	Reputation systems for human computation
-	Quality assurance in distributed human intelligence tasks
-	Social sensing in crowdsourcing and human computation
-	Domain-specific challenges in crowdsourcing and human computation
-	Social sensing in human computation approaches
-	Use cases and applications of social media for human computation

The workshop will accept:
•	Regular research papers (6-8 pages)
•	Applications / Demonstrators (4 pages)
•	Position papers (2-4 pages)

All submissions must be formatted according to ACM Web Science
submission guidelines (
and submitted through the SoHuman 2013 EasyChair system:

All submissions will be reviewed in a peer-review process by at least
two members of the program committee. At least one author of each paper
will need to register for and attend the workshop to present the paper.

•	Abstract submission: March 15, 2013  (recommended)
•	Paper submission: March 20, 2013
•	Notification of acceptance: April 3, 2013
•	Camera-ready papers: April 17, 2013
•	Workshop date: May 1, 2013

Results of the workshop (papers, findings from the discussion panel)
will be published as separate workshop proceedings (either as
Springer Lecture Notes in Computer Science or as CEUR-WS Proceedings).
Depending on the quality of the submissions there will also be an
opportunity to publish extended versions of the papers as a special
issue in a major journal.
