MoodBar: Increasing new user retention in Wikipedia through lightweight socialization
Socialization in online communities allows existing members to welcome and
recruit newcomers, introduce them to community norms and practices, and sustain
their early participation. However, socializing newcomers does not come for
free: in large communities, socialization can result in a significant workload
for mentors and is hard to scale. In this study we present results from an
experiment that measured the effect of a lightweight socialization tool on the
activity and retention of newly registered users attempting to edit for the
first time Wikipedia. Wikipedia is struggling with the retention of newcomers
and our results indicate that a mechanism to elicit lightweight feedback and to
provide early mentoring to newcomers improves their chances of becoming
long-term contributors.Comment: 9 pages, 5 figures, accepted for presentation at CSCW'1
Fostering Cross-institutional Collaboration for Open Educational Resources Production
An editable version of this resource is available at http://open.umich.edu/education/med/oernetwork/reports/oer-collab-report/2010.Although there are over a quarter of a million open courses published by an increasing number of universities, it remains unclear whether Open Educational Resources (OER) is scalable and productively sustainable. The challenge is compounded when OER is examined in the light of its potential to allow both educators and learners in developing countries to contribute geographically bound learning resources in the context of varied infrastructural, technological and skill constraints. Between October and December 2009, 52 participants involved in various roles related to Health OER from five universities (one in the USA, two in Ghana and two in South Africa) were interviewed. The aim of the study was to investigate sustainability of OER based on possible cross-institutional collaboration as well as social and technical challenges in creating and sharing OER materials. The analytical framework was adopted from prior research in related areas: distributed scientific collaboration; cyber infrastructure; open source development; and Wikipedia. We adopted a qualitative approach for data collection, which included semi structured interviews and document analysis. The findings were analyzed and reported with many direct quotations included. The outcome of the data analysis is a model for productive, scalable, and sustainable OER based on cross-institutional collaboration. The report concludes with practical recommendations on how to the model can be operationalized.William and Flora Hewlett Foundationhttp://deepblue.lib.umich.edu/bitstream/2027.42/94546/1/2010.12.08_oer_collaboration_report-final_0.pd
Improving Textual Merge Result
International audienceIn asynchronous collaborative systems, merging is an essential component. It allows to reconcile modifications made concurrently as well as managing software change through branching. The collaborative system is in charge to propose a merge result that includes user's modifications. The users now have to check and adapt this result. The adaptation should be as effort-less as possible, otherwise, the users may get frustrated and will quit the collaboration. The objective of this paper is to improve the result quality of the textual merge tool that constitutes the default merge tool of distributed version control systems. The basic idea is to study the behavior of the concurrent modifications during merge procedure. We identified when the existing merge techniques under-perform, and we propose solutions to improve the quality of the merge. We finally compare with the traditional merge tool through a large corpus of collaborative editing
Online epistemic communities: theoretical and methodological directions for understanding knowledge co-elaboration in new digital spaces
This paper presents, illustrates and discusses a generic framework for studying knowledge co-elaboration in online epistemic communities (âOECsâ). Our approach is characterised by: considering knowledge co-elaboration as a design activity; distinguishing discussion and production spaces in OECs; characterising participation via the notion of role; fine-grained analyses of meaning, content and communicative functions in interactions. On this basis, three key issues for ergonomics research on OECs are discussed and illustrated by results from our previous studies on OSS and Wikipedia. One issue concerns the interrelation between design (task) and regulation. Whereas design task-oriented activity is distributed among participants, we illustrate that OCEs function with specialised emerging roles of group regulation. However, the task-oriented activity also functions at an interpersonal level, as an interplay of knowledge-based discussion with negotiation of competencies. Another issue concerns the foci of activity on the (designed) knowledge object. Based on a generic task model, we illustrate asymmetry and distinctiveness in tasksâ foci of participants. The last issue concerns how design-use mediation is ensured by specific forms of mediation roles in OECs. Finally we discuss the degree of generality of our framework and draw some perspectives for extending our framework to other OECs
INCREASING THE WILLINGNESS TO COLLABORATE ONLINE: AN ANALYSIS OF SENTIMENT-DRIVEN INTERACTIONS IN PEER CONTENT PRODUCTION
We investigate mechanisms that trigger collaborative work behavior in online peer communities. We regard the collaboration among Wikipedia editors as a social process influenced by specific communication practices. We analyze and quantify the way Wikipedia editors communicate their feedback and support towards each othersâ work in form of sentiments and opinions, and explore to what extent this influences online trust among them. We show that peer content production in Wikipedia is influenced by sharing sentiments during discussions among editors. At the global level, sharing sentiments positively influences the level of online trust. We also find a significant difference in the amount of online trust among editors who share mainly positive or mainly negative sentiments. We further suggest that providing and receiving especially supportive feedback expressed in form of positive sentiments and opinions may be beneficial in terms of virtual teamwork
Division of Labour and Sharing of Knowledge for Synchronous Collaborative Information Retrieval
a b s t r a c t Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques
EquiP: A Method to Co-Design for Cooperation
In Participatory Design (PD), the design of a cooperative digital solution should involve all stakeholders in the co-design. When one stakeholderâs position is weaker due to socio-cultural structures or differences in knowledge or abilities, PD methods should help designers balance the power in the design process at both the macro and micro levels. We present a PD method that addresses the power relations arising during the design process and draws on theories about participation and power in the design and organisation of change processes. We contribute to Computer Supported Cooperative Work (CSCW) by using the PD method to design computer support for cooperation on cognitive rehabilitation between people with Mild Acquired Brain Injuries (MACI) and their healthcare professionals, where strengthening the cooperation is considered an element of patient empowerment. This method is presented as a contribution to the intersection between PD and CSCW. The discussion of power in PD contributes to the discussion of cooperation in CSCW. We found that EquiP supported the creation of choices, and hence the âpower toâ influence the design. This method can contribute to a power âequilibriumâ and a positive-sum power relation in PD sessions involving all stakeholders.publishedVersio
Flexibility Relative to What? Change to Research Infrastructure
It is often said that, in the face of an ever-changing world, infrastructure must remain flexible. Yet, what is meant by change remains glib and, consequently, so too do our studies on flexibility. In this paper, we develop three sensitizing concepts to investigate change to research infrastructure: 1) technoscientific: changes in research objects, scientific methods, and instruments; 2) sociotechnical: changes in social organization, coordination and, collaboration tools; and data sharing techniques; and 3) institutional: changes in funding and regulatory regimes. The majority of studies of âinformation infrastructureâ have focused on the sociotechnical facet, and so we offer the two additional facets of change to help sensitize researchers to empirical instances of these encountered in the field, and to broaden the research agenda. To elaborate these concepts, we focus on a long-term research infrastructure that has been investigating HIV disease for nearly thirty years: The Multicenter AIDS Cohort Study (MACS). Over time, the MACS has faced tremendous changes in its science, collaboration and communication tools, its data and specimen repositories, its institutional environment, and the disease itself. Before we can begin to characterize flexibility, we must understand the nature of change research infrastructures face. We conclude by outlining a research agenda that will match forms of flexibility to the heterogeneity of changes an infrastructure may encounter
