David Redmiles is a Professor in the Department of Informatics at the University of California, Irvine (UCI). He is the author of over 100 research publications integrating the areas of software engineering, human-computer interaction, and computer-supported cooperative work. From 2004 to 2011, he chaired the Department of Informatics at UCI.

Awareness, Trust, and Tool Support in Distance Collaborations

Our day-to-day activities and especially our work increasingly involve distance collaborations. As individuals, we work in isolation and integrate results via collaborative technologies. Also, with great frequency, we see new kinds of collaborative technology and variations on existing technologies supporting new tasks or new aspects of activities. This trend of distributed, collaborative work and the technologies supporting it fuel one another and the combination motivates the research that my group has performed for the past several years. The problems are fascinating in their diversity and human-centered nature. Indeed, while we study and develop technologies for supporting distance collaborations, we equally study individuals' and organizations' reactions to, use of, and disuse of these technologies. In this talk, I will discuss a wide range of technologies we have developed, theoretical findings we have made, and approaches we take in researching distance collaborations. While the theories and concepts apply to multiple domains, the examples discussed are almost exclusively in the context of collaborative software engineering. Examples of the topics I will discuss include the following: tool support, visual user interfaces, awareness and trust among collaborators, effects of gender and culture, and empirical work in organizations and laboratory settings. Most of all, I wish to share with the audience the excitement and the overall promise of research in this area.


Dr. David W. McDonald is an associate professor in The Information School at University of Washington. Dr. McDonald has ongoing projects studying mass interaction in Wikipedia and technology and media use in the home. He has published research on ubiquitous sensing for behavior change, collaboration in distributed contributor systems, collaborative authoring, recommendation systems, and public use of large screen displays. His general research interests span Computer-Supported Cooperative Work (CSCW) and Human-Computer Interaction (HCI). Dr. McDonald recently finished serving as a Program Director for the Human Centered Computing (HCC), Network Science and Engineering (NetSE), and Social Computational Systems (SoCS) programs at the National Science Foundation (NSF).

How A Million People Could Save the Planet: The Next Research Agenda for Collaborative Computing

The rise of large-scale systems that allow diverse communities of individuals to each contribute their unique talents, perspectives and skills has necessitated a shift in how we think about the relationship between people and computing. Systems like Wikipedia, PatientsLikeMe, InnoCentive, or Mechanical Turk illustrate the potential for these new types of systems to interleave the talents of people and machines to begin solving problems that neither people nor machines could solve alone. Various terms are being used to describe these systems that begin to interleave the efforts of people and machines: Distributed Contributor Systems, Human Computation, Collective Intelligence, Web Science and Social Computational Systems (SoCS). One aspect of SoCS is that any single disciplinary stance (computational, behavioral, or social) is insufficient to understand characteristics for which we must account when designing and building these types of systems.

This shift toward integrating larger numbers of people and machines into a designed system raises a number of distinct research challenges for: programming languages that express complex relationships between the human contributions and machine contributions in a computation, data management schemes that effectively handle massive amounts of data with missing, inconsistent and dirty values and which track the provenance, and software architectures that effectively scale from small numbers of machines and participants through massive numbers of machines and participants.

The talk will introduce Social Computational Systems (SoCS) to claim that Human Computer Interaction (HCI) and collaborative computing are experiencing a paradigm shift that encompasses larger numbers of connected, participating users and machines. As a result, the study and design of SoCS is important to the future of HCI and collaborative computing. I outline a small selection of prior research that illustrates a progression of my own research thinking about how to study, characterize, design and build systems where the interleaving of computation and people are essential to the way the systems perform. I illustrate working in a disciplinary intersection through a study that applies machine learning techniques to understand how members of one large online community identify behavioral patterns of other members of the community. The talk concludes by outlining key research challenges for a Social Computational Systems (SoCS) research agenda.


Raquel Recuero is an associate professor at UCPel. Her research interests focus on the online social networks and virtual communities, specially on how people negotiate conversations in the online environment and the information flows these networks allow. She is the author of several books, including Redes Sociais na Internet (Social Networks in the Internet) and Conversação em Rede (Network Conversations). She also worked as a research consultant for several companies, including Google, MySpace, and Lolapps.


Curriculum Lattes:

Redes Sociais Online, Capital Social e Cooperação

A proposta enfoca a discussão das redes sociais online como facilitadoras dos processos colaborativos através da construção de capital social. A partir desta premissa, discutem-se os sites de rede social e as redes sociais como fenômenos contemporâneos, cujas práticas conversacionais originam novas formas de negociar e construir valores sociais, contribuindo para uma maior pluralidade de valores disponíveis que podem ser utilizados pelos atores como elementos de cooperação e colaboração. Discutem-se também as estruturas das redes, as motivações e as perspectivas estruturais dessas redes e suas principais diferenças daqueles grupos constituídos exclusivamente nos espaços offline.
