Community networks are digital infrastructures designed to strengthen bonds and build social capital between members of a community, facilitating accomplishment of goals. As we consider how community network implementations can be improved, we recognize the potential that social translucence and activity notification introduces to other forms of CSCW. We investigate how the underlying notion of persistent virtual identity -- established at logon -- impacts user perception of community networks and their social capital production process. To approach this question, we introduce a design model that reconciles various computer-mediated communication research contributions with support for typical community network scenarios of use. Using this model, we perform an inspection on existing community network implementations. Based on the insight gained through this analysis, we introduce a generic prototype that allows survey of user reaction to community network design elements under differing conditions of persistent virtual identity implementation and usage motivation -- the results frame a value-chain understanding of conceptual tradeoffs.
Recommenders everywhere: The wikilens communitymaintained recommender system
"... Suppose you have a passion for items of a certain type, and you wish to start a recommender system around those items.

Suppose you have a passion for items of a certain type, and you wish to start a recommender system around those items. You want a system like Amazon or Epinions, but for cookie recipes, local theater, or microbrew beer. How can you set up your recommender system without assembling complicated algorithms, large software infrastructure, a large community of contributors, or even a full catalog of items? WikiLens is open source software that enables anyone, anywhere to start a community-maintained recommender around any type of item. We introduce five principles for community-maintained recommenders that address the two key issues: (1) community contribution of items and associated information; and (2) finding items of interest. Since all recommender communities start small, we look at feasibility and utility in the small world, one with few users, few items, few ratings. We describe the features of WikiLens, which are based on our principles, and give lessons learned from two years of experience running wikilens.org.

This work examines the interplay of inter-personal and inter-organizational trust, two distinct but related concepts, through a theoretic inter-organizational trust-based security model for a multi-agent system information-sharing community. A calculus that mathematically models trust building at the inter-organizational level is at the heart of this model. In interorganizational or inter-firm exchange, the role of the boundary spanner, an organizational representative, is important in reducing asymmetries that may exist between the two parties. Trust is a crucial component to the dyadic interaction at the inter-personal or boundary spanner level, and the trust established at this level affects, as well, the overall quality of the relationship at the inter-organizational level. Trust, as an aspect of social control, is thus viewed a more effective mechanism for security in an open, distributed system, like an information-sharing community. The inter-organizational trust-based security model proposed herein represents a soft security approach. It affords several important benefits over traditional hard security mechanisms used in open systems – robustness, scalability, and adaptability. The inter-organizational trust-based model is an important contribution to the computational security community, as other open systems applications of a distributed or pervasive nature could adapt it and realize its benefits. It also is one of few attempts to model trust building at either the inter-organizational or inter-personal level.

Abstract. Virtual learning communities bring together people from diverse backgrounds and provide the basis for knowledge construction and sharing. Important processes for the community to function as a whole have been identified and examined through existing systems. Although existing systems attempt to support these processes, the absence of a complete community model, and the personalisation and adaptation to the individual rather than the community compose the main obstacles to their holistic success. A computational framework is proposed, to support the community to function as an entity rather than concentrating to the individual person.

ABSTRACT. Emergence of web services like YouTube, Flickr etc. has transformed the way we share our lifestyles with family, friends and colleagues. The significance of these social contents can be enhanced if they are shared with the right person, at the right location and at the right time. Towards this vision, we present DroPicks, a tool for sharing social web contents utilizing augmented everyday artefacts used as digital data container. Our initial user evaluation shows DroPicks as a promising tool for our intended purpose. This poster summarizes the design and implementation of DroPicks. 1.
