Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.Sat Aug 18 13:22:24 CEST 2007Community Software Development with the Astrophysics Simulation Collaboratory2001software development community This paper addresses issues given by the template developed by the GCE WG for the journal.

Submitted to: Journals Production Department, John Wiley {\&} Sons, Ltd., Chichester, West Sussex, PO19 1UD, U.K. SUMMARY We describe a Grid-based collaboratory that supports the collaborative development and use of advanced simulation codes. Our implementation of this collaboratory uses a mix of Web technologies (for thin-client access) and Grid services (for...Sat Aug 18 13:22:24 CEST 2007PaperbackDecemberThe Digital University: Building a Learning Community2001digital learning university community {University education continues to be revolutionized by the use of Web-based teaching and learning systems. Following on from "The Digital University: Reinventing the Academy", this book provides a fully up-to-date and practical guide to using and implementing this important technology. Looking specifically at asynchronous collaboration, it covers:- policies- management of collaboration- distance learning- support for authoring- course design- educational metadata schemaand will be an essential buy for managers, lecturers, administrators, department heads and researchers.It includes a foreword by Ben Shneiderman, Director of the HCI Laboratory at the University of Maryland, USA.}Sat Aug 18 13:22:24 CEST 2007HardcoverNovemberWiki : Web Collaboration2005collaboration internet wiki online no-tag community new_media hypertext {Wikis are Web-based applications that allow all users not only to view pages but also to change them. The recent success of the Internet encyclopedia Wikipedia has drawn increasing attention from private users, small organizations and enterprises to the various possible uses of wikis. Their simple structure and straightforward operation make them a serious alternative to expensive content management systems and also provide a basis for many applications in the area of collaborative work. We show the practical use of wikis in carrying out projects for users as well as for maintainers. This includes a step-by-step introduction to wiki philosophy, social effects and functions, a survey of their controls and components, and the installation and configuration of the wiki clones MediaWiki and TWiki. In order to exemplify the possibilities of the software, we use it as a project tool for planning a conference.}Sat Aug 18 13:22:24 CEST 2007NatureApril7136664--667Quantifying social group evolution4462007social_network sociology scientific complexity networks_dynamic swarm social-networks generations k-clique socialnetworking cell community cultural-evolution network social-structure tagging taggingpres cooperation collaboration quantifying dynamics networktheory social_networks social social-dynamics networks quantitative sociophysics percolation group evolution phone social-network complex_network social_analysis auto-correlation no-tag 07 Sat Aug 18 13:22:24 CEST 2007PaperbackSeptemberLife on the Screen: Identity in the Age of the Internet1997computers sts no-tag new-media cybercultures digilife net culture i_own_it sociology mary-weaver identity iown web20 internet online university theory psychology communities cybersociology bricolage cyberculture computing art community cyberethnography multiple-identities gender agency digitalyouth ethnography virtual social online-communities computer games mmo learning technology ident media play mud book online-identities {Sherry Turkle is rapidly becoming the sociologist of the Internet, and that's beginning to seem like a good thing. While her first outing, <i>The Second Self: Computers and the Human Spirit</i>, made groundless assertions and seemed to be carried along more by her affection for certain theories than by a careful look at our current situation, <i>Life on the Screen</i> is a balanced and nuanced look at some of the ways that cyberculture helps us comment upon real life (what the cybercrowd sometimes calls RL). Instead of giving in to any one theory on construction of identity, Turkle looks at the way various netizens have used the Internet, and especially MUDs (Multi-User Dimensions), to learn more about the possibilities available in apprehending the world. One of the most interesting sections deals with gender, a topic prone to rash and partisan pronouncements. Taking as her motto William James's maxim "Philosophy is the art of imagining alternatives," Turkle shows how playing with gender in cyberspace can shape a person's real-life understanding of gender. Especially telling are the examples of the man who finds it easier to be assertive when playing a woman, because he believes male assertiveness is now frowned upon while female assertiveness is considered hip, and the woman who has the opposite response, believing that it is easier to be aggressive when she plays a male, because as a woman she would be considered "bitchy." Without taking sides, Turkle points out how both have expanded their emotional range. Other topics, such as artificial life, receive an equally calm and sage response, and the first-person accounts from many Internet users provide compelling reading and good source material for readers to draw their own conclusions. }
