    Caring About Sharing: Couples' Practices in Single User Device Access
    (Proceedings of the 2016 ACM International Conference on Supporting Group Work, 2016) Jacobs, Maia; Cramer, Henriette; Barkhuus, Louise
    Most devices today are developed adhering to a one-user paradigm. Yet within households, couples are often sharing devices and accounts. In this paper we take an in-depth look at sharing practices and preferences of cohabiting couples, and discuss the nuances of existing practices surrounding accounts and devices. We present a qualitative interview and diary study with ten couples, consisting of 20 individual interviews, and individual 8-day diaries. Dichotomous access models do not reflect the sharing practices of our couples; in which intent, access, and utilization all characterized sharing behaviors. We present a detailed description of the intentional and unintentional sharing practices our participants used in their day to day interactions and discuss the different challenges that particularly one type of content pose in terms of issues of privacy. We discuss implications for accounts and devices based on the ways in which content was shared and hidden among collocated couples. We provide a structured account of these sharing practices to inform the design of multi-user settings within future technologies.

    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.

    Contested Collective Intelligence: Rationale, Technologies, and a Human-Machine Annotation Study
    (Computer Supported Cooperative Work (CSCW): Vol. 21, 2012) De Liddo, Anna; Sándor, Ágnes; Buckingham Shum, Simon
    We propose the concept of Contested Collective Intelligence (CCI) as a distinctive subset of the broader Collective Intelligence design space. CCI is relevant to the many organizational contexts in which it is important to work with contested knowledge, for instance, due to different intellectual traditions, competing organizational objectives, information overload or ambiguous environmental signals. The CCI challenge is to design sociotechnical infrastructures to augment such organizational capability. Since documents are often the starting points for contested discourse, and discourse markers provide a powerful cue to the presence of claims, contrasting ideas and argumentation, discourse and rhetoric provide an annotation focus in our approach to CCI. Research in sensemaking, computer-supported discourse and rhetorical text analysis motivate a conceptual framework for the combined human and machine annotation of texts with this specific focus. This conception is explored through two tools: a social-semantic web application for human annotation and knowledge mapping (Cohere), plus the discourse analysis component in a textual analysis software tool (Xerox Incremental Parser: XIP). As a step towards an integrated platform, we report a case study in which a document corpus underwent independent human and machine analysis, providing quantitative and qualitative insight into their respective contributions. A promising finding is that significant contributions were signalled by authors via explicit rhetorical moves, which both human analysts and XIP could readily identify. Since working with contested knowledge is at the heart of CCI, the evidence that automatic detection of contrasting ideas in texts is possible through rhetorical discourse analysis is progress towards the effective use of automatic discourse analysis in the CCI framework.

    Exploring Appropriation of Enterprise Wikis:
    (Computer Supported Cooperative Work (CSCW): Vol. 21, 2012) Stocker, Alexander; Richter, Alexander; Hoefler, Patrick; Tochtermann, Klaus
    The purpose of this paper is to provide both application-oriented researchers and practitioners with detailed insights into conception, implementation, and utilization of intra-organizational wikis to support knowledge management and group work. Firstly, we report on three case studies and describe how wikis have been appropriated in the context of a concrete practice. Our study reveals that the wikis have been used as Knowledge Base, Encyclopedia and Support Base, respectively. We present the identified practices as a result of the wiki appropriation process and argue that due to their open and flexible nature these wikis have been appropriated according to the users’ needs. Our contribution helps to understand how platforms support working practices that have not been supported by groupware before, or at least not in the same way. Secondly, three detailed implementation reports uncover many aspects of wiki projects, e.g., different viewpoints of managers and users, an investigation of other sources containing business-relevant information, and perceived obstacles to wiki projects. In this context, our study generates a series of lessons learned for people who intend to implement wikis in their own organizations, including the awareness of usage potential, the need for additional managerial support, and clear communication strategies to promote wiki usage.

    Soft peer review. Social software and distributed scientific evaluation
    (From CSCW to Web 2.0: European Developments in Collaborative Design Selected Papers from COOP08, 2008) Taraborelli, Dario
    The debate on the prospects of peer-review in the Internet age and the increasing criticism leveled against the dominant role of impact factor indicators are calling for new measurable criteria to assess scientific quality. Usage-based metrics offer a new avenue to scientific quality assessment but face the same risks as first generation search engines that used unreliable metrics (such as raw traffic data) to estimate content quality. In this article I analyze the contribution that social bookmarking systems can provide to the problem of usage-based metrics for scientific evaluation. I suggest that collaboratively aggregated metadata may help fill the gap between traditional citation-based criteria and raw usage factors. I submit that bottom-up, distributed evaluation models such as those afforded by social bookmarking will challenge more traditional quality assessment models in terms of coverage, efficiency and scalability. Services aggregating user-related quality indicators for online scientific content will come to occupy a key function in the scholarly communication system.
