Preface
The International Conference on Social Informatics was first held in Warsaw,
Poland in 2009, followed by Laxenburg, Austria in 2010. Singapore, a major
hub in the Asia Pacific regionwell known for its multi-racial and multi-cultural
society, is proud to have hosted the third conference. Both SocInfo 2009 and
SocInfo2010weresmallmeetingsthatcoveredmainlythecomputingperspective
ofsocialinformatics.This orientationbroadensatSocInfo 2011,reachingoutto

differentbackgroundsmeetandmix:acomputationalsocialsciencemeltingpot.
Ultimately, the quality of a conference depends upon the papers included in
its program. We received 68 full papers and 13 poster-paper submissions from
across the globe, coming from 40 different countries, showcasing the interna-
tional character of the conference. The Programand General Co-chairs wish to
acknowledge the great work of our seven publicity chairs, who advertised the
conference across the different regions. Given the multidisciplinary nature of
someofthepapers,wehadtoemployuptoeightreviewsforsomepaperstoob-
tain adequate inputs from different perspectives, before deciding on the papers’
inclusioninthe program.Ourprogramcommittee members,supportedbysome
external reviewers, turned in over 290 reviews. Based on these expert reviews,
we selected 15 full papers, 8 short papers, and 13 poster papers for the final
program.
The healthy number of submissions, followed by the rigorous review process
byamulti-disciplinaryProgramCommittee,ledtoaveryexcitingprogramthat
meets our primary mission to make SocInfo 2011a premier venue for socialand
computer scientists to exchange their latest research ideas as a basis for better
integrated scholarship from the two disciplines going forward.

Technology); and tutorials by Adam Wierzbicki (Polish-Japanese Institute of
Information Technology) and Stuart W. Shulman (University of Massachusetts
Amherst). The conference also featured a Symposium on Social Dynamics in
Online Gaming to create a forum for the discussion of topics regarding online
gaming and the dynamics of player interactions.
Without the support of several funding agencies, organizations as well as
individuals, organizing SocInfo 2011 successfully would not have been possible.
These include sponsorships from AOARD, AFOSR, the Lee Foundation, the
