Wikiotics: The Interactive Language Instruction Wiki

Ian Sullivan, James R. Garrison, Matthew Curinga

While most existing wiki systems are geared toward editing text documents, we have built Wikiotics to enable the collaborative creation of interactive multimedia materials most needed in language instruction. In our demonstration, we will show several types of interactive lessons that can be created from simple multimedia elements. We will also show the lesson creation/editing interfaces and how our smart phone app can simplify the process of capturing local media and integrating that new media into existing lessons.

PukiWiki-Java Connector, a Simple API for Saving Data of Java Programs on a Wiki

Takashi Yamanoue, Kentaro Oda, Koichi Shimozono

Experimental implementation of SDK for Java Programs, PukiWiki-Java Connector, which makes an illusion that wiki pages as persistent data store, is shown. A Java program of them can be running on a wiki page and it can save its data on the page. The Java program consists of PukiWiki which is a popular wiki in Japan, the plug-in which starts up Java Applets. A Java Applet with default access privilege cannot store its data at the local host. We have constructed the API for the applets to ease data persistent at a remote host. We also combined the API and the wiki system by introducing a wiki plugin and tags for starting up Java Applets. Applet generated persistent data resides in wiki texts side by side. We have successfully ported useful programs such as a simple text editor, a simple music editor, a simple draw program and programming environments in a PukiWiki system using this connector.

Collaborative Video Editing for Wikipedia

Michael Dale

Collaborative video for Wikipedia faces several challenges from social and community adoption to technology limitations. This presentation explores how each of these problems are being addressed. The presentation focuses on building a collaborative educational video community and how the html5 technology platform has evolved to better support rich media applications such as HTML5 video editing in the browser and standardization around the royalty free WebM video format. Finally we propose a in-browser collaborative video sequencer to enable broad participation in video editing within Wikimedia projects.

Wiki4EAM – Using Hybrid Wikis for Enterprise Architecture Management

Florian Matthes, Christian Neubert

Enterprise architecture management (EAM) is a challenging task, modern enterprises have to face. This task is often addressed via heavy-weight and expensive EAM tools to collect, structure, visualize and analyze architectural information. A major problem in EAM is the mismatch between the existing unstructured information sources and the rigid information structures and collaboration mechanisms provided by today’s EAM tools.

To address this mismatch, researchers at Technische Universität München established in 2010 a community of experienced enterprise architects from 25 large German enterprises to pursue a different, wiki-based approach to EAM. The idea is to start with existing unstructured information sources captured as wiki pages (e.g., derived from Office documents) and then to incrementally and collaboratively enrich the wiki pages with attributes, types and integrity rules as needed for architecture modeling, visualization and analysis.

An off-the shelf commercial enterprise wiki (Tricia by infoAsset AG) provides the required incremental information structuring capabilities as so-called Hybrid Wikis. Customizable in-browser visualizations are provided by the System Cartography Tool developed at Technische Universität München.

Don’t Bite the Newbies: How Reverts Affect the Quantity and Quality of Wikipedia Work

Aaron Halfaker, Aniket Kittur, John Riedl

Reverts are important to maintaining the quality of Wikipedia. They fix mistakes, repair vandalism, and help enforce policy. However, reverts can also be damaging, especially to the aspiring editor whose work they destroy. In this research we analyze 400,000 Wikipedia revisions to understand the effect that reverts had on editors. We seek to understand the extent to which they demotivate users, reducing the workforce of contributors, versus the extent to which they help users improve as encyclopedia editors. Overall we find that reverts are powerfully demotivating, but that their net influence is that more quality work is done in Wikipedia as a result of reverts than is lost by chasing editors away. However, we identify key conditions – most specifically new editors being reverted by much more experienced editors – under which reverts are particularly damaging. We propose that reducing the damage from reverts might be one effective path for Wikipedia to solve the newcomer retention problem.

Mentoring in Wikipedia: A Clash of Cultures

David R. Musicant, Yuqing Ren, James A. Johnson, John Riedl

The continuous success of Wikipedia depends upon its capability to recruit and engage new editors, especially those with new knowledge and perspectives. Yet Wikipedia over the years has become a complicated bureaucracy that may be difficult for newcomers to navigate. Mentoring is a practice that has been widely used in offline organizations to help new members adjust to their roles. In this paper, we draw insights from the offline mentoring literature to analyze mentoring practices in Wikipedia and how they influence editor behaviors. Our quantitative analysis of the Adopt-a-user program shows mixed success of the program. Communication between adopters and adoptees is correlated with the amount of article editing done by adoptees shortly after adoption. Our qualitative analysis of the communication between adopters and adoptees suggests that several key functions of mentoring are missing or not fulfilled consistently. Most adopters focus on establishing their legitimacy rather than acting proactively to guide, protect, and support the long-term growth of adoptees. We conclude with recommendations of how Wikipedia mentoring programs can evolve to take advantage of offline best practices.

“How Should I Go from __ to __ Without Getting Killed?” Motivation and Benefits in Open Collaboration

Katherine Panciera, Mikhil Masli, Loren Terveen

Many people rely on open collaboration projects to run their computer (Linux), browse the web (Mozilla Firefox), and get information (Wikipedia). While these projects are successful, many such efforts suffer from lack of participation. Understanding what motivates users to participate and the benefits they perceive from their participation can help address this problem. We examined these issues through a survey of contributors and information consumers in the Cyclopath geographic wiki. We analyzed subject responses to identify a number of key motives and perceived benefits. Based on these results, we articulate several general techniques to encourage more and new forms of participation in open collaboration communities. Some of these techniques have the potential to engage information consumers more deeply and productively in the life of open collaboration communities.

The technical session Wikis in the Workplace will feature three presentations. See the schedule for details on when and where to go.

The Success of Corporate Wiki Systems: An End User Perspective

Zeeshan Ahmed Bhatti, Serge Baile, Hina Mahboob Yasin

With the ever increasing use of Web 2.0 sites on the internet, the use of Web 2.0 based tools is now employed by organizations across the globe. One of the most widely used Web 2.0 tools in organizations is wiki technology, particularly in project management. It is important for organizations to measure the success of their wiki system implementation. With the advent of new technologies in the market and their deployment by the firms, it is necessary to investigate how they can help organizations execute processes in a better way. In this paper we present a theoretical model for the measurement of corporate wikis’ success from the end-user’s perspective based on the theoretical foundation of DeLone & McLean’s IS success model. We extend the model by incorporating contextual factors with respect to wiki technology in a project management task. This study intends to help firms to understand in a better way, how they can use wikis to achieve an efficient, effective and improved end-user performance. This would also be helpful for companies engaged in wiki development business to improve their products keeping in view the perceptions of wiki end-users.

ICKEwiki: Requirements and Concepts for an Enterprise Wiki for SMEs

Stefan Voigt, Frank Fuchs-Kittowski, Detlef Hüttemann, Michael Klafft, Andreas Gohr

Extensive empirical studies of the use of Web 2.0 applications in small and medium-sized enterprises, together with requirements analyses among pilot users, served as the basis to compile requirements for a wiki knowledge and collaboration platform. This experience report discusses the requirements and their implementation in a new wiki engine (ICKEwiki). Initial field experiences with the ICKEwiki implemented among three pilot users are analyzed and potentials for the use and refinement of the platform are presented.

Wiki Scaffolding: Helping Organizations to Set Up Wikis

Oscar Díaz, Gorka Puente

Organizational wikis are framed by an existing organization. This makes these wikis be especially vigilant upon (1) facilitating the alignment of the wiki with organizational practices, (2) engaging management or (3), promoting employees’ participation. To this end, we advocate for the use of “wiki scaffoldings”. A wiki scaffolding is a wiki installation that is provided at the onset, before any contribution is made. It aims to frame wiki contribution along the concerns already known in the hosting organization in terms of glossaries, schedules, organigrams and the like. Thus, wiki contributions do not start from scratch but within a known setting. This paper introduces a language to capture wiki scaffolding in terms of FreeMind’s mind maps. These maps can later be mapped into wiki installations in MediaWiki. The paper seeks to validate the approach in a twofold manner. Firstly, by providing literature quotes that suggest the need for scaffolding. Secondly, by providing scaffolding examples for wikis reported in the literature. The findings suggest that wiki scaffolding can be useful to smoothly align wiki activity along the practices of the hosting organization from the onset.

The technical session Wikipedia as a Global Phenomenon will feature three presentations. See the schedule for details on when and where to go.

Hot off the Wiki: Dynamics, Practices, and Structures in Wikipedia’s Coverage of the Tōhoku Catastrophes

Brian Keegan, Darren Gergle, Noshir Contractor

Wikipedia editors are uniquely motivated to collaborate around current and breaking news events. However, the speed, urgency, and intensity with which these collaborations unfold also impose a substantial burden on editors’ abilities to effectively coordinate tasks and process information. We analyze the patterns of activity on Wikipedia following the 2011 Tōhoku earthquake and tsunami to understand the dynamics of editor attention and participation, novel practices employed to collaborate on these articles, and the resulting coauthorship structures which emerge between editors and articles. Our findings have implications for supporting future coverage of breaking news articles, theorizing about motivations to participate in online community, and illuminating Wikipedia’s potential role in storing cultural memories of catastrophe.

Collective Memory Building in Wikipedia: The Case of North African Uprisings

Michela Ferron, Paolo Massa

Since December 2010, a series of protests and uprisings have shocked North African countries such as Tunisia, Egypt, Libya, Syria, Yemen and more. In this paper, focusing mainly on the Egyptian revolution, we provide evidence of the intense edit activity occurred during these uprisings on the related Wikipedia pages. Thousands of people provided their contribution on the content pages and discussed improvements and disagreements on the associated talk pages as the traumatic events unfolded. We propose to interpret this phenomenon as a process of collective memory building and argue how on Wikipedia this can be studied empirically and quantitatively in real time. We explore and suggest possible directions for future research on collective memory formation and controversial events in Wikipedia.

Wikipedia World Map: Method and Application of Map-like Wiki Visualization

Cheong-Iao Pang, Robert P. Biuk-Aghai

Wiki are popular platforms for collaborative editing. In volunteer-driven wikis such as Wikipedia, which attracts millions of authors editing articles on a diverse range of topics, contributors’ editing activity results in certain semantic coverage of topic areas. Obtaining an understanding of a given wiki’s semantic coverage is not easy. To solve this problem, we have devised a method for visualizing a wiki in a way similar to a geographic map. We have applied our method to Wikipedia, and generated visualizations for several Wikipedia language editions. This paper presents our wiki visualization method and its application.
