A process of distillation is needed to boil down a large information space into information that is concise and organized. We take a system-augmented approach to the problem by creating a set of tools with which human editors can collaboratively distill a large amount of informal information. Two design principles, which we will define as incremental diagenesis and incremental summarization, help editors flexibly distill the informal information. Our system, Arkose, is built as a demonstration of these principles, providing the necessary tools for distillation. These tools include a number of visualization and information retrieval mechanisms, as well as an authoring tool and a navigator for the information space. They support a gradual increase in the order and reusability of the information space and allow various levels of intermediate states of a distillation.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132551264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore how feedback might improve teamwork in a controlled experiment where groups interact through chat rooms. Collaborators who receive high feedback ratings use different language than poor collaborators (e.g. more words, fewer assents, and less affect-laden language). Further, feedback affects language use. This suggests that a system could use linguistic analysis to automatically provide and visualize feedback to teach teamwork. To this end, we present GroupMeter, a system that applies principles discovered in the experiment to provide feedback both from peers and from automated linguistic analysis.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127800140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper introduces, on the basis of a field study, the concept of stigmergy to the analysis of coordinative practices in architectural work. It distinguishes between practices of stigmergy and articulation work. Stigmergy is understood as coordination achieved by acting directly on the evidence of work previously accomplished and articulation work is understood as second order efforts to coordinate collaborative work. Furthermore, this leads to a distinction between representational artifacts associated with practices of stigmergy and coordination mechanisms in the service of articulation work.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128490812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the potential of emerging 3D telepresence technology for facilitating paramedic - physician collaboration while providing emergency medical trauma care we conducted a between-subjects post-test experimental lab study. During a simulated emergency situation 60 paramedics diagnosed and treated a trauma victim while working alone or in collaboration with a physician via 2D video or a 3D proxy. Analysis of paramedics' task performance shows that the fewest harmful procedures occurred in the 3D proxy condition. Paramedics in the 3D proxy condition also reported higher levels of self-efficacy. These results indicate 3D telepresence technology has potential to improve paramedics' performance of complex emergency medical tasks and improve emergency trauma health care when designed appropriately.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114228919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we analyze over two years of data from CiteULike, a social bookmarking system for tagging academic papers. We propose six tag metrics-tag growth, tag reuse, tag non-obviousness, tag discrimination, tag frequency, and tag patterns-to understand the characteristics of a social bookmarking system. Using these metrics, we suggest possible design heuristics to implement a social bookmarking system for CiteSeer, a popular online scholarly digital library for computer science. We believe that these metrics and design heuristics can be applied to social bookmarking systems in other domains.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"13 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113955845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Managing such diverse views is a persistent problem in cooperative group work. The Wikipedian community has responded with an evolving body of policies that provide shared principles, processes, and strategies for collaboration. We employ a grounded approach to study a sample of active talk pages and examine how policies are employed as contributors work towards consensus. Although policies help build a stronger community, we find that ambiguities in policies give rise to power plays. This lens demonstrates that support for mass collaboration must take into account policy and power.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"23 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114025049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subramanian","doi":"10.1145/1316624.1316640","DOIUrl":"https://doi.org/10.1145/1316624.1316640","url":null,"abstract":"The windows and doorways that connect offices to public spaces are a site for people to gather awareness information and initiate interaction. However, these portals often reveal more information to the public area than the office occupant would like. As a result, people often keep doors and window blinds closed, which means that nobody can gather awareness information, even those with whom the occupant would be willing to share. One solution to this problem is a co-present media space - a computer-mediated video connection at the boundary between an office and a public area. These systems can provide both greater privacy control to the occupant and greater overall awareness information to observers. To see how co-present media spaces would work in real world settings, we built what we believe are the first ever co-present media spaces, and deployed them in two offices. From observations gathered over fifteen months, it is clear that the systems can do a better job of balancing the occupant's need for privacy and the observers' need for awareness better, than a standard window. However, we also identified a number of issues that affected the use and the success of the systems: the existence of alternate information sources, confusion with existing social norms, disparities between effort and need, and reduced interactional subtlety for observers in the public area. Our work contributes both a novel arrangement of a media space for co-present collaborators, and the first investigation into the design factors that affect the use and acceptance of these systems.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"57 6 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123388412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
