Rather than being a limiting factor, “symmetry of ignorance” can provide the foundation for social creativity. Bringing different points of view together and trying to create a shared understanding among all stakeholders can lead to new insights, new ideas, and new artifacts. Social creativity can be supported by new media that allow owners of problems to contribute to framing and solving these problems. These new media need to be designed from a meta-design perspective by creating environments in which stakeholders can act as designers and be more than consumers.

First, we define time graphs to extend the traditional notion of an evolving directed graph, capturing link creation as a point phenomenon in time. Second, we develop definitions and algorithms for time-dense community tracking, to crystallize the notion of community evolution. We develop these tools in the context of Blogspace , the space of weblogs (or blogs). Our study involves approximately 750K links among 25K blogs. We create a time graph on these blogs by an automatic analysis of their internal time stamps. We then study the evolution of connected component structure and microscopic community structure in this time graph. We show that Blogspace underwent a transition behavior around the end of 2001, and has been rapidly expanding over the past year, not just in metrics of scale, but also in metrics of community structure and connectedness. This expansion shows no sign of abating, although measures of connectedness must plateau within two years. By randomizing link destinations in Blogspace, but retaining sources and timestamps, we introduce a concept of randomized Blogspace . Herein, we observe similar evolution of a giant component, but no corresponding increase in community structure. Having demonstrated the formation of micro-communities over time, we then turn to the ongoing activity within active communities. We extend recent work of Kleinberg [11] to discover dense periods of "bursty" intra-community link creation.

NusEye is an information system for syndicated content which is extended to support the collaborative activity of users, also known as social navigation. Dourish and Chalmers [1] define social navigation as provoking a user to move through an information space guided by the activity of others in that space. NusEye augments syndicated content with social navigation. NusEye allows users to apply ad-hoc keywords, or tags, to sources of Web syndicated information. Applied tags are visible to all users in the system. NusEye can identify the most popular tags and webfeeds. The entire community benefits from the aggregation and collective tagging efforts of each individual by being able to search tags and/or users in order to find new webfeed sources. Furthermore, NusEye offers special content analysis based on keyword tags. Users can apply various dynamically updated analyses on the content generated by groups of sources. The major points of design include the selection of an interface in which social communities and networks can form from the use of tags, content analysis that is beneficial for syndicated content, and the presentation of analysis results. A prototype version of NusEye has been built and is currently being used to test and explore the concept of social navigation in syndicated content.

However, many mainstream world-building applications do not offer quick and appropriate ways of developing interactive and user-driven content that can be easily shared with other users. Many education-orientated applications also require built-in tracking and evaluation mechanisms. Evaluation of virtual worlds and communities is difficult enough as it is. While commercial game engines offer a form of task performance tracking, they typically lack non-violent ways of supporting interaction and collaborative teamwork. The chance to help students and the public to learn by creating and collaborating through the development of contextually relevant worlds is exciting. It is perhaps best served by an application containing a feature set designed specifically for content designers to create learning environments. In this paper we suggest some features that might help educational designers build better 'learning as sharing' experiences.

The focus is on children's play of an educational game, Treasure Hunt, and the way children's interactions in play frame developmental processes involving arithmetic with base-10 blocks. Sixty-four third and fourth graders were grouped in same- and mixed-grade dyads. Analyses of interactions revealed that players were frequently involved with jointly structuring arithmetical problems involving base-10 blocks. However, the arithmetical goals that members of dyads created often differed as labor became divided in their activity. Two findings were of particular interest: (1) differences in divisions of labor as a function of players' grades and grades of their opponents led to construction of different arithmetical goals, and (2) differences in goals led to different sequences in children's strategic developments, sequences that differed from the developmental trajectory in our matched controls.

In this paper we describe a collaborative, computer-based framework for argumentation that supports the dialogue process in ways which stimulate belief revision leading to conceptual change and development in science. This pedagogy is specified as a prescriptive ‘dialogue game’, which models features of the tutorial process. Within this scheme, the learner adopts the role of an ‘explainer’ whilst the system plays a facilitating role, and these participants collaborate to develop a shared explanatory model of a qualitative, causal domain. The design framework includes an abstract world model of a qualitative causal system, some ‘commonsense’ reasoning rules, an interaction language and dialogue strategies and tactics, that are co-ordinated within a facilitating dialogue game. A prototype CoLLeGE (Computer based Lab for Language Games in Education) system implements the framework and operates as a dialogue modelling work-bench for demonstrating, investigating and developing the approach. An empirical study showed that students revised their beliefs and improved their explanatory models, and held to their revised and improved conceptions in a delayed post-test. In using CoLLeGE to simulate these dialogues, we found that the tutor’s low-level tactical pedagogies emerged and developed reactively during the dialogues, in response to conceptual difficulties experienced by the students.

In recent years, increasing attention has been devoted to the social bases of cognition, taking into consideration how social processes in groups and teams affect performance. This article investigates when and how teams in collaborative learning environments engage in building and maintaining mutually shared cognition, leading to increased perceived performance. In doing so, this research looks for discourse practices managing the co-construction of mutually shared cognition and reveals conditions in the interpersonal context that contribute to engagement in these knowledge-building practices. A comprehensive theoretical framework was developed and tested. The constructs in the model were measured with the Team Learning Beliefs & Behaviors Questionnaire and analyzed using regression and path analysis methodology. Results showed that both interpersonal and sociocognitive processes have to be taken into account to understand the formation of mutually shared cognition, resulting in higher perceived team performance. 10.1177/1046496406292938 Social and Cognitive Factors Driving Teamwork in Collaborative Learning Environments: Team Learning Beliefs and Behaviors Piet Van den Bossche Wim Gijselaers Mien Segers Paul Kirschner doi:10.1177/1046496406292938 Small Group Research, Vol. 37, No. 5.

This paper also describes various limitations of current recommendation methods and discusses possible extensions that can improve recommendation capabilities and make recommender systems applicable to an even broader range of applications. These extensions include, among others, an improvement of understanding of users and items, incorporation of the contextual information into the recommendation process, support for multcriteria ratings, and a provision of more flexible and less intrusive types of recommendations.

However, understanding and building for everyday practices is crucial for ubicomp designers, in order to push the technological development in the directions needed. We have developed and tested a ubiquitous computing prototype supporting collaborative scheduling. It is based on Pin&Play, a surface-based networking technology with interactive pushpins. The team of a local film festival was engaged in the development process, which resulted in a partial implementation illustrating how their current work practice could be supported. Drawing on this particular design case, we report findings and discuss challenges for ubicomp technology in general.

When people play the game they help determine the contents of images by providing meaningful labels for them. If the game is played as much as popular online games, we estimate that most images on the Web can be labeled in a few months. Having proper labels associated with each image on the Web would allow for more accurate image search, improve the accessibility of sites (by providing descriptions of images to visually impaired individuals), and help users block inappropriate images. Our system makes a significant contribution because of its valuable output and because of the way it addresses the image-labeling problem. Rather than using computer vision techniques, which don't work well enough, we encourage people to do the work by taking advantage of their desire to be entertained.

Groups of four participants completed four web design tasks. Each participant worked on two tasks, each task with a different partner who was either co-located or remote, connected via IM. In one condition, each participant had one co-located and one remote partner. In a second condition, both partners were remote. We examined communication, division of labor, and task performance as a function of condition. The results indicated that nearly all participants divided their time unequally between projects, but less unequally in the remote/remote condition. In the co-located/remote condition, participants favored the task with the co-located partner. The results show that the effects of IM differ depending on people's multiple tasks are distributed across space. We propose a new IM interface that promotes awareness of multiple collaborators on multiple tasks.

Collaborators are willing to share their data, and in many cases they also want to selectively import data from others --- but must occasionally diverge when they disagree about uncertain or controversial facts or values. For this reason, traditional data sharing and data integration approaches are not applicable, since they require a globally consistent data instance. Additionally, many of these approaches do not allow participants to make updates; if they do, concurrency control algorithms or inconsistency repair techniques must be used to ensure a consistent view of the data for all users.In this paper, we develop and present a fully decentralized model of collaborative data sharing, in which participants publish their data on an ad hoc basis and simultaneously reconcile updates with those published by others. Individual updates are associated with provenance information, and each participant accepts only updates with a sufficient authority ranking, meaning that each participant may have a different (though conceptually overlapping) data instance. We define a consistency semantics for database instances under this model of disagreement, present algorithms that perform reconciliation for distributed clusters of participants, and demonstrate their ability to handle typical update and conflict loads in settings involving the sharing of curated data.

Using corpus linguistic methods and factor analysis of word counts for features of formality and informality, we show that the greater the degree of post-production editorial control afforded by the system, the more formal and standardized the language of the collaboratively-authored documents becomes, analogous to that found in traditional print encyclopedias. Paradoxically, users who faithfully appropriate such systems create homogeneous entries, at odds with the goal of open-access authoring environments to create diverse content. The findings shed light on how users, acting through mechanisms provided by the system, can shape (or not) features of content in particular ways. We conclude by identifying sub-genres of web-based collaborative authoring environments based on their technical affordances.

One approach is to model the set of possible sequencings with a graph, but the process of designing and maintaining the graph may be tedious and error-prone. This paper presents some ideas to overcome this, inpired by swarm intelligence techniques. Problems that may arise, as well as possible solutions, are presented.
