    Bloggers and Readers Blogging Together: Collaborative Co-creation of Political Blogs
    (Computer Supported Cooperative Work (CSCW): Vol. 20, 40634) Baumer, Eric P. S.; Sueyoshi, Mark; Tomlinson, Bill
    A significant amount of research has focused on blogs, bloggers, and blogging. However, relatively little work has examined blog readers, their interactions with bloggers, or their impact on blogging. This paper presents a qualitative study focusing specifically on readers of political blogs to develop a better understanding of readers’ interactions with blogs and bloggers. This is the first such study to examine the same blogging activity from both readers’ and bloggers’ perspectives. Readers’ significance and contributions to blogs are examined through a number of themes, including: community membership and participation; the relationship between political ideology, reading habits, and political participation; and differences and similarities between mainstream media (MSM) and blogs. Based on these analyses, this paper argues that blogging is not only a social activity, but is a collaborative process of co-creation in which both bloggers and readers engage. Implications of this finding contribute to the study and understanding of reader participation, to the design of technologies for bloggers and blog readers, and to the development of theoretical understandings of social media.

    Characterizations of Online Harassment: Comparing Policies Across Social Media Platforms
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Pater, Jessica A.; Kim, Moon K.; Mynatt, Elizabeth D.; Fiesler, Casey
    Harassment in online spaces is increasingly part of public debate and concern. Pervasive problems like cyberbullying, hate speech, and the glorification of self-harm have highlighted the breadth and depth of harassment taking place online. In this study we conduct a content analysis of the governing policies for fifteen social media platforms as they relate to harassment (of oneself and/or of community members) and other associated behaviors. We find that there is a striking inconsistency in how platform-specific policies depict harassment. Additionally, how these policies prescribe responses to harassment vary from mild censuring to the involvement of law enforcement. Finally, based on our analysis and findings, we discuss the potential for harnessing the power of the online communities to create norms around problematic behaviors.

    Collaborative Feed Reading in a Community
    (Proceedings of the 2009 ACM International Conference on Supporting Group Work, 2009) Aizenbud-Reshef, Netta; Guy, Ido; Jacovi, Michal
    Feed readers have emerged as one of the salient applications that characterize Web 2.0. Lately, some of the available readers introduced social features, analogously to other Web 2.0 applications, such as recommendations and tagging. Yet, most of the readers lack collaborative features, such as the ability to share feeds in a community or divide the reading task among community members. In this paper we describe CoffeeReader, a web-based feed reader, which combines social and collaborative features, and is deployed in a small community within our company. CoffeeReader provides awareness of other users' feed lists and read status; it enables information sharing such as tags and recommendations; and aims to support coordination of filtering through feeds to locate important items. We compare these group collaboration features of CoffeeReader with emerging features in publicly available feed readers; present the outcomes of using CoffeeReader within our community; and discuss our findings and their implications on making feed readers more collaborative.

    Crisis Informatics for Everyday Analysts: A Design Fiction Approach to Social Media Best Practices
    (Proceedings of the 2018 ACM International Conference on Supporting Group Work, 2018) Dailey, Dharma; Soden, Robert; LaLone, Nicolas
    The importance of social media usage during crisis has been well established in academic and practitioner communities. Yet, the promise of rendering insights from social media for responders in a consistent and reliable manner remains a challenge and accepted standards of practice have yet to emerge. Inspired by a May 2017 workshop consisting of 15 Crisis Informatics practitioners from 3 continents, we imagine a training curriculum aimed at developing the necessary skills to harness social media data during a crisis. We call the recipients of that training Crisis Informatics Research Technicians (CIRT). We offer this design fiction to stimulate a conversation among Crisis Informatics scholars, Human-Computer Interaction scholars, crisis response professionals, and the public on best practices, tools, limitations, and ethics of using social media to improve crisis response.

    Designing an Application for Social Media Needs in Emergency Public Information Work
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Hughes, Amanda Lee; Shah, Rohan
    Emergency responders increasingly use social media as a means to monitor public information, gather information that could be used in response efforts, and communicate important information during emergency events. However, the adoption of social media into emergency management processes poses socio-technical challenges such as issues of credibility and trust, lack of organizational support, poor tools, and a shortage of resources and training. This study designs, implements, and evaluates an application that supports the work practice of emergency public information officers and their need to gather, monitor, sort, and report social media activity. Based on prior work that examines how social media and the forms of public participation enabled by it are changing public information practice, we iteratively design and evaluate application prototypes using a human-centered process--moving from low-fidelity paper prototypes to a high-fidelity digital prototype that is ready for field use.

    Digital Traces of Online Self-Organizing and Problem Solving in Disaster
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Kogan, Marina
    Natural disasters are associated with breakdown of existing structures, but they also result in creation of new social ties in the process of self-organization and problem solving by those affected. In highly-distributed setting of social media, collaborative arrangements must depend on the aspects of work that facilitate (or not) the creation of a shared information space-such as an explicit shared site of work and visible, legible record of the activity. In my dissertation I investigate what organizational structures emerge through problem solving in the context of more or less explicit shared site of work and more or less visible record of activity.

    Discovering Habits of Effective Online Support Group Chatrooms
    (Proceedings of the 2012 ACM International Conference on Supporting Group Work, 2012) Mayfield, Elijah; Wen, Miaomiao; Golant, Mitch; Penstein Rosé, Carolyn
    For users of online support groups, prior research has suggested that a positive social environment is a key enabler of coping. Typically, demonstrating such claims about social interaction would be approached through the lens of sentiment analysis. In this work, we argue instead for a multifaceted view of emotional state, which incorporates both a static view of emotion (sentiment) with a dynamic view based on the behaviors present in a text. We codify this dynamic view through data annotations marking information sharing, sentiment, and coping efficacy. Through machine learning analysis of these annotations, we demonstrate that while sentiment predicts a user's stress at the beginning of a chat, dynamic views of efficacy are stronger indicators of stress reduction.

    Effects of Feedback and Peer Pressure on Contributions to Enterprise Social Media
    (Proceedings of the 2009 ACM International Conference on Supporting Group Work, 2009) Brzozowski, Michael J.; Sandholm, Thomas; Hogg, Tad
    Increasingly, large organizations are experimenting with internal social media (e.g., blogs, forums) as a platform for widespread distributed collaboration. Contributions to their counterparts outside the organization's firewall are driven by attention from strangers, in addition to sharing among friends. However, employees in a workplace under time pressures may be reluctant to participate and the audience for their contributions is comparatively smaller. Participation rates also vary widely from group to group. So what influences people to contribute in this environment?In this paper, we present the results of a year-long empirical study of internal social media participation at a large technology company, and analyze the impact attention, feedback, and managers' and coworkers' participation have on employees' behavior. We find feedback in the form of posted comments is highly correlated with a user's subsequent participation. Recent manager and coworker activity relate to users initiating or resuming participation in social media. These findings extend, to an aggregate level, the results from prior interviews about blogging at the company and offer design and policy implications for organizations seeking to encourage social media adoption.

    A Framework and Future Direction for Studying Productive Applications of Social Media / Social Networking Sites
    (Proceedings of the 2012 ACM International Conference on Supporting Group Work, 2012) Roback, Andrew J.
    I am researching how non-governmental organizations (NGOs) utilize social media and social networking sites (SM/SNS) in their efforts to organize, inform, and serve the communities they operate in as well as how they use these technologies to communicate and disseminate information. This study will gather data on persons posting on behalf of NGOs and examine SM/SNS data with the goal of developing a framework for both future research and contextual application of SM/SNS as a mediating artifact by NGOs. Many previous studies have addressed similar issues, but those studies are limited in context (e.g. one large software manufacturer) and they typically use only one type of research method. I will address this issue by aggregating a large data set and employing mixed methods to improve the generalizability of my findings and present a replicable framework for future studies of organizational use of SM/SNS.

    From Consumer to Community: Factors of Influence in the Purchasing Decision Making Process
    (Proceedings of the 2012 ACM International Conference on Supporting Group Work, 2012) Gligorijevic, Barbara
    The impacts of online collaboration and networking among consumers on social media (SM) websites which are featuring user generated content in a form of product reviews, ratings and recommendations (PRRR) as an emerging information source is the focus of this research. The proliferation of websites where consumers are able to post the PRRR and share them with other consumers has altered the marketing environment in which companies, marketers and advertisers operate. This cross-sectional study explored consumers' attitudes and behaviour toward various information sources (IS), used in the information search phase of the purchasing decision-making process. The study was conducted among 300 international consumers. The results were showing that personal and public IS were far more reliable than commercial. The findings indicate that traditional marketing tools are no longer viable in the SM milieu.

    The Gap between Producer Intentions and Consumer Behavior in Social Media
    (Proceedings of the 2012 ACM International Conference on Supporting Group Work, 2012) Rader, Emilee; Velasquez, Alcides; Hales, Kayla D.; Kwok, Helen
    It can be difficult for social media users to tell who is paying attention to what they post. As producers of content, Facebook users make assumptions about who will be part of their intended audience. However, when the same user's role shifts to that of consumer, the criteria for consumption depends on factors outside of the original producer's control. This creates a gap between producer intentions and consumer behavior; producing content that is actually consumed by one's intended audience is neither guaranteed nor easily confirmed.

    Journalists as Crowdsourcerers: Responding to Crisis by Reporting with a Crowd
    (Computer Supported Cooperative Work (CSCW): Vol. 23, No. 4-6, 41974) Dailey, Dharma; Starbird, Kate
    Widespread adoption of new information communication technologies (ICTs) is disrupting traditional models of news production and distribution. In this rapidly changing media landscape, the role of the journalist is evolving. Our research examines how professional journalists within a rural community impacted by Hurricane Irene successfully negotiated a new role for themselves, transforming their journalistic practice to serve in a new capacity as leaders of an online volunteer community. We describe an emergent organization of media professionals, citizen journalists, online volunteers, and collaborating journalistic institutions that provided real-time event coverage. In this rural context, where communications infrastructure is relatively uneven, this ad hoc effort bridged gaps in ICT infrastructure to unite its audience. In this paper, we introduce a new perspective for characterizing these information-sharing activities: the “human powered mesh network” extends the concept of a mesh network to include human actors in the movement of information. Our analysis shows how journalists played a key role in this network, and facilitated the movement of information to those who needed it. These findings also note a contrast between how HCI researchers are designing crowdsourcing platforms for news production and how crowdsourcing efforts are forming during disaster events, suggesting an alternative approach to designing for emergent collaborations in this context.

    LiveDissent: A Media Platform for Remote Participation in Activist Demonstrations
    (Proceedings of the 2018 ACM International Conference on Supporting Group Work, 2018) Hamilton, William A.; Lupfer, Nic; Kerne, Andruid
    Social media platforms such as Twitter and Facebook have become a critical tools for the coordination of activist movements and demonstrations. Additionally, live streaming platforms like Periscope have started to emerge as modalities for reporting on and remotely experiencing activist activities. In this design fiction, we present LiveDissent, a fictional media platform that leverages both established and emerging technologies to support remote participation in activist demonstrations. These technologies include mobile live streaming, telepresence robots, unmanned aerial vehicles, and digitally augmented picket signs. LiveDissent brings these technologies together into an aggregated platform for remotely watching and participating in demonstrations. We discuss a planned in the wild study at an upcoming demonstration, through which we will explore the design and implications of social media and telepresence for participation in activism. Finally, our authors' statement connects to related prior work and explores potential research and ethics questions.

    Modeling User Intrinsic Characteristic on Social Media for Identity Linkage
    (Proceedings of the 2018 ACM International Conference on Supporting Group Work, 2018) Yu, Xianqi; Sun, Yuqing; Bertino, Elisa; Li, Xin
    Most users on social media have intrinsic characteristics, such as interests and political views, that can be exploited to identify and track them. It raises privacy and identity issues in online communities. In this paper we investigate the problem of user identity linkage on two behavior datasets collected from different experiments. Specifically, we focus on user linkage based on users' interaction behaviors with respect to content topics. We propose an embedding method to model a topic as a vector in a latent space so as to interpret its deep semantics. Then a user is modeled as a vector based on his or her interactions with topics. The embedding representations of topics are learned by optimizing the joint-objective: the compatibility between topics with similar semantics, the discriminative abilities of topics to distinguish identities, and the consistency of the same user's characteristics fromtwo datasets. The effectiveness of our method is verified on real-life datasets and the results show that it outperforms related methods.

    Raising Your Eminence inside the Enterprise Social Network
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Kremer-Davidson, Shiri; Ronen, Inbal; Leiba, Lior; Kaplan, Avi; Barnea, Maya
    Companies are motivating their employees to become socially engaged in enterprise social networks as a means to raise employee engagement. This is also beneficial for employees as it provides an opportunity for them to get a voice and raise their eminence. Unfortunately, not all employees are born social butterflies" and many have difficulties in becoming more socially active. Failing to engage in an effective manner creates frustration which over time decreases their activity and lowers their chance to become socially eminent. This paper is a first of a kind study that reveals insights on social behavioral patterns of socially eminent employees. We extracted a comprehensive set of tips and recommendations to help employees become more socially eminent and investigate if and how eminent employees engage differently than others. We conducted interviews with top socially eminent employees and a quantitative inspection of bloggers behavioral patterns. Furthermore, we show that indeed best practices stated by socially eminent employees are fulfilled by eminent bloggers and less by others. We also found differences in how socially eminent employees engage compared to less eminent employees."

    Regrets, I've Had a Few: When Regretful Experiences Do (and Don't) Compel Users to Leave Facebook
    (Proceedings of the 2018 ACM International Conference on Supporting Group Work, 2018) Guha, Shion; Baumer, Eric P.S.; Gay, Geri K.
    Previous work has explored regretful experiences on social media. In parallel, scholars have examined how people do not use social media. This paper aims to synthesize these two research areas and asks: Do regretful experiences on social media influence people to (consider) not using social media? How might this influence differ for different sorts of regretful experiences? We adopted a mixed methods approach, combining topic modeling, logistic regressions, and contingency analysis to analyze data from a web survey with a demographically representative sample of US internet users (n=515) focusing on their Facebook use. We found that experiences that arise because of users' own actions influence actual deactivation of their Facebook account, while experiences that arise because of others' actions lead to considerations of non-use. We discuss the implications of these findings for two theoretical areas of interest in HCI: individual agency in social media use and the networked dimensions of privacy.

    The Role of Social Media in Participatory Democracy: A Case Study of Facebook Groups
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Gachau, James Ngetha
    This dissertation investigates three Facebook groups as case studies of the role of social media in enhancing participatory democracy. I argue that the groups were formed to provide avenues for articulating discourses that are counter to the dominant voices of their societies. The study posits that in stratified societies there typically emerges a dominant hegemonic public opinion, which is inimical to the needs, hopes, desires, and aspirations of subordinate classes. The key research question I ask is: How are these groups using social media to build and articulate identities that question the dominant public opinion about issues that have traditionally been controlled by a hegemonic voice?

    A Social Commerce Platform
    (Supplementary Proceedings of the 9th International Conference on Communities & Technologies - Transforming Communities, 2019) AlArdaj, Aisha Ahmed; Solaiman, Ellis
    The advancement of social media and e-commerce have created a new model of online shopping, which is called social commerce. Social commerce platforms need to integrate social features with commercial functions to improve user experience and to enhance trust between consumers and sellers. Current social media platforms such as Instagram, mostly focus on social aspects with limited commercial functions. Also traditional e-commerce websites have commercial capabilities but with limited social features. In this demo, we present an interface for a social commerce platform that integrates both social features and commercial functions to help consumers in their purchase decision processes.

    Social Media for Sensitive Disclosures and Social Support: The Case of Miscarriage
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Andalibi, Nazanin
    I study self-disclosure and investigate ways in which social computing systems can be designed to allow people to disclose negatively-perceived or stigmatized experiences and find support in their social networks. My prior work has given me insight about online disclosures of depression and sexual abuse, the role of anonymity in support seeking, and the ways that people respond to such disclosures. In my dissertation I will use miscarriage as a context to investigate online disclosure and response practices around stigmatized and traumatizing topics with the goal of improving both theory and social media design practices.
