Social Filtering (using social networks for neighborhood generation) is compared to Collaborative Filtering with respect to prediction accuracy in the domain of rating clubs. After reviewing background and related work, we present an extensive empirical study where over thousand participants from a social networking community where asked to provide ratings for clubs in Munich. We then compare a typical traditional CF-approach to a social recommender / social filtering approach where friends from the underlying social network are used as rating neighborhood and analyze the experiments statistically. Surprisingly, the social filtering approach outperforms the CF approach in all variants of the experiment. The implications of the experiment for professional and private-life collaborative environments and services where recommendations play a role are discussed. We conclude with future perspectives on social recommender systems, especially in upcoming mobile environments.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"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":"130889149","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}

Systems that worked well with smaller numbers or particular types of users must change to meet the needs of an expanding and diversified user base. A first step toward growth is to cultivate new users. We present results from research that examines one approach to the challenge of attracting new users to a large-scale computing infrastructure. We describe gateway organizations and the important social and technical support they provide, which help potential users to conceptualize a use for the infrastructure and increase their willingness and ability to use it.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"92 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":"134581539","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 present an analysis of how the vlogging system transformed social and instructional interactions in clinical training. Additionally, we describe how the faculty's appropriation of vlog technology was initially challenged by the presentation of divergent methodology in vlog records, and increased transparency of teaching practices in video records.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"43 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":"133687898","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 identify when team members collaborate, why they collaborate, and how they collaborate during information seeking activities, we conducted a field study of a multidisciplinary patient care team. We found that the unit secretary, a non-clinical team member, had characteristics of various types of gatekeepers identified in previous studies. However, unlike those gatekeepers, the unit secretary also played a particularly active role during information seeking activities. Most medical information systems design focus on supporting collaboration amongst clinical staff. Our study highlights the importance of also supporting non-clinical team members.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"393 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":"127354132","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}

These dependencies create a need for communication and coordination that requires continuous effort by developers. Empirical studies, including our own, suggest that technical dependencies among software components create social dependencies among the software developers implementing those components. Based on this observation, we developed Ariadne, a plug-in for Eclipse. Ariadne analyzes software projects for dependencies and collects authorship information about projects relying on configuration management repositories. Ariadne can \"translate\" technical dependencies among components into social dependencies among developers. We have created visualizations to convey dependency information and the presence of coordination problems identified in our previous work. We believe the information conveyed in the visualizations will prove useful for software developers.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"7 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":"130615086","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 propose two design strategies, illustrated with mock-ups, to support creativity with awareness: (1) Automatically summarize and recommend ideational activities from system logs; (2) Allow collaborators to enter status of work activity, making these activity updates visible on social and temporal dimensions. Our analysis also suggests an integrated framework of metrics to evaluate creativity as a long-term collaborative activity.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"19 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":"129969455","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}

This research seeks to gain an understanding of the issues related to managing different social networks through one system, in particular looking at how users of these systems present themselves when they are using one site to keep in contact with both their past social groups from school and their current social connections in the workplace. To do this, we examined online profile pages and interviewed employees at a large software development company who frequently use the website Facebook, a site primarily used by college students and young graduates transitioning into the work force. The outcome of this initial case study is a framework for understanding how users manage self-presentation while maintaining social relationships in heterogeneous networks.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"11 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":"117011520","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 recommend strategies for cross-service tag integration at the points of tag storage and tag search, rather than at the conventional point of tag entry. We close with a research agenda around this strategy.","PeriodicalId":445069,"journal":{"name":"Proceedings of the 2007 ACM International Conference on Supporting Group Work","volume":"24 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":"134190215","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 discusses how toallsupport users - different types of stakeholders - in the collaborative creation of mixed reality configurations as an integral part of expressing their ideas about an urban project, distinguishing between different types and levels of cooperation.
