Web edition, Copyright © 2011 by Joseph Michael Reagle Jr. CC-NC-SA 3.0 Purchase at Amazon.com | Barnes and Noble | IndieBound | MIT Press Wikipedia's style of collaborative production has been lauded, lambasted, and satirized. Despite unease over its implications for the character (and quality) of knowledge, Wikipedia has brought us closer than ever to a realization of the centuries-old Author Bio & Research Blog pursuit of a universal encyclopedia. Good Faith Collaboration: The Culture of Wikipedia is a rich ethnographic portrayal of Wikipedia's historical roots, collaborative culture, and much debated legacy. Foreword Preface to the Web Edition Praise for Good Faith Collaboration Preface Extended Table of Contents "Reagle offers a compelling case that Wikipedia's most fascinating and unprecedented aspect isn't the encyclopedia itself — rather, it's the collaborative culture that underpins it: brawling, self-reflexive, funny, serious, and full-tilt committed to the 1.

Instructor Basics: Howtouse Wikipedia As Ateaching Tool
Instructor Basics: How to use Wikipedia as a teaching tool Wiki Education Foundation Wikipedia is the free online encyclopedia that anyone can edit. One of the most visited websites worldwide, Wikipedia is a resource used by most university students. Increasingly, many instructors around the world have used Wikipedia as a teaching tool in their university classrooms as well. In this brochure, we bring together their experiences to help you determine how to use Wikipedia in your classroom. We’ve organized the brochure into three parts: Assignment planning Learn key Wikipedia policies and get more information on designing assignments, with a focus on asking students to write Wikipedia articles for class. During the term Learn about the structure of a good Wikipedia article, the kinds of articles students should choose to improve, suggestions for what to cover in a Wikipedia lab session, and how to interact with the community of Wikipedia editors. After the term See a sample assessment structure that’s worked for other instructors. 2 Instructor Basics Assignment planning Understanding key policies Since Wikipedia started in 2001, the community of volunteer editors – “Wikipedians” – has developed several key policies designed to ensure Wikipedia is as reliable and useful as possible. Any assignment you integrate into your classroom must follow these policies. Understanding these cornerstone policies ensures that you develop an assignment that meets your learning objectives and improves Wikipedia at the same time.

What Is a Wiki? Tutorial 1 for New Wikieducators
What is a Wiki? Tutorial 1 for new WikiEducators wikieducator.org book - Generated using the open source mwlib toolkit - see http://code.pediapress.com for more information 2 Introducing a Wiki Objectives In this tutorial we will: • provide an overview of what wikis are, • and show some examples of their different uses. • discuss the advantages and disadvantages of using wikis to develop content • describe the main features of WikiEducator What is a Wiki? The name "Wiki" was chosen by Ward Cunningham - - the creator of the first Wiki. It is a shortened form of "wiki- wiki", the Hawaiian word for quick. A wiki is a web site that is generally editable by anyone with a computer, a web browser, and an internet connection. Wikis use a quick and easy syntax to allow users to apply formatting to text and create links between pages. This simple formatting syntax means that authors no longer need to learn the complexities of HTML to create content on the web. The main strength of a wiki is that it gives people the ability to work collaboratively on the same document. The only software you need is an Wiki wiki sign outside Honolulu International Internet browser. Consequently, wikis are used Airport. (Image courtesy of A. Barataz) for a variety of purposes.

WMF Advisory Board Beesley Starling
Advisory Board interviews conducted at Wikimania: Angela Beesley Starling August 24-28, 2009 Key themes: . Need for experimentation/innovation within Wikimedia . Need for prioritization and rationalization of Wiki projects . Need for renewed efforts towards the charitable mission What is your history with Wikimedia? . Was on the first Board of Trustees, joined in 2003. Stepped down from that role and became Chair of the Advisory Board when that was set up. Husband is a MediaWiki developer on staff at Wikimedia (Tim Starling). Now working with Jimmy on Wikia. What are your major concerns in thinking about Wikimedia’s development over the next five years? . Concern that as the WMF gets bigger, the connection to the community will be weaker. Big software challenges; and it is harder to try out new things since the site is so big o Difficulty trying out new things; concerned that the community will object to change o We need new processes, a way for the Foundation to say they need to try something out. For example, with flagged revisions, it was not clear how or whether it would will get rolled out, when it might live, who would be responsible for it, and whether it would be for a trial period only, and if so what metrics would determine success of the trial. o Too few technical staff at Wikipedia, and too few people to review the code of volunteers. Major changes, particularly user-facing ones, are less likely to happen. The tech staff is focused on management of volunteers – filling in other bits around the edges. -

Detecting Wikipedia Vandalism Using Wikitrust*
Detecting Wikipedia Vandalism using WikiTrust? Lab Report for PAN at CLEF 2010 B. Thomas Adler1, Luca de Alfaro2, and Ian Pye3 1 [email protected], Fujitsu Labs of America, Inc. 2 [email protected], Google, Inc. and UC Santa Cruz (on leave) 3 [email protected], CloudFlare, Inc. Abstract WikiTrust is a reputation system for Wikipedia authors and content. WikiTrust computes three main quantities: edit quality, author reputation, and content reputation. The edit quality measures how well each edit, that is, each change introduced in a revision, is preserved in subsequent revisions. Authors who perform good quality edits gain reputation, and text which is revised by sev- eral high-reputation authors gains reputation. Since vandalism on the Wikipedia is usually performed by anonymous or new users (not least because long-time vandals end up banned), and is usually reverted in a reasonably short span of time, edit quality, author reputation, and content reputation are obvious candi- dates as features to identify vandalism on the Wikipedia. Indeed, using the full set of features computed by WikiTrust, we have been able to construct classifiers that identify vandalism with a recall of 83.5%, a precision of 48.5%, and a false positive rate of 8%, for an area under the ROC curve of 93.4%. If we limit our- selves to the set of features available at the time an edit is made (when the edit quality is still unknown), the classifier achieves a recall of 77.1%, a precision of 36.9%, and a false positive rate of 12.2%, for an area under the ROC curve of 90.4%.
