Supporting Awareness of Content-related Controversies in a Wiki-based Learning Environment

Title: Supporting Awareness of Content-related Controversies in a Wiki-based Learning Environment

Authors: Sven Heimbuch (University of Duisburg-Essen), Daniel Bodemer (University of Duisburg-Essen)

Abstract: User generated content in Wikis is mainly distributed on the article view and its corresponding talk page. Potentials of analysing and supporting discussants’ knowledge construction processes on the level of talk pages have still been rarely researched. The presented experimental study addresses this issue by providing external representations of content-related controversies which were led by contradictory evidence between discussants to foster awareness on socio-cognitive conflicts which can be beneficial for learning. Its aim is to investigate how increased salience of controversies can guide participants’ (N = 81) navigation and learning processes. Three conditions differing in their degree of awareness support were implemented in this study. Results indicate that the implementation of awareness representations helped students to focus on meaningful discussion threads. Findings suggest that Wiki talk page users can benefit from additional structuring aids.

Geographic and Linguistic Normalization: Towards a Better Understanding of the Geo-linguistic Dynamics of Knowledge

Title: Geographic and Linguistic Normalization: Towards a Better Understanding of the Geo-linguistic Dynamics of Knowledge

Authors: Han-Teng Liao, Thomas Petzold

Abstract: This paper proposes a method of geo-linguistic normalization to advance the existing comparative analysis of open collaborative communities, with multilingual Wikipedia projects as the example. Such normalization requires data regarding the potential users and/or resources of a geolinguistic unit.

Contropedia – The Analysis and Visualization of Controversies in Wikipedia Articles

Title: Contropedia – The Analysis and Visualization of Controversies in Wikipedia Articles

Authors: Erik Borra, Esther Weltevrede, Paolo Ciuccarelli, Andreas Kaltenbrunner, David Laniado, Giovanni Magni, Michele Mauri, Richard Rogers, Tommaso Venturini

Abstract: Collaborative content creation inevitably reaches situations where different points of view lead to conflict. In Wikipedia, one of the most prominent examples of collaboration online, conflict is mediated by both policy and software, and conflicts often reflect larger societal debates. Contropedia is a platform for the analysis and visualization of such controversies in Wikipedia. Controversy metrics are extracted from activity streams generated by edits to, and discussions about, individual articles and groups of related articles. An article’s revision history and its corresponding discussion pages constitute two parallel streams of user interactions that, taken together, fully describe the process of the collaborative creation of an article. Our proposed platform, Contropedia, builds on state of the art techniques and extends current metrics for the analysis of both edit and discussion activity and visualizes these both as a layer on top of Wikipedia articles as well as a dashboard view presenting additional analytics. Furthermore, the combination of these two approaches allows for a deeper understanding of the substance, composition, actor alignment, trajectory and liveliness of controversies on Wikipedia. Our research aims to provide a better understanding of sociotechnical phenomena that take place on the web and to equip citizens with tools to fully deploy the complexity of controversies. Contropedia is useful for the general public as well as user groups with specific interests such as scientists, students, data journalists, decision makers and media communicators.

Measuring the Quality of Edits to Wikipedia

Title: Measuring the Quality of Edits to Wikipedia

Authors: Susan Biancani

Abstract: Wikipedia is unique among reference works both in its scale and in the openness of its editing interface. The question of how it can achieve and maintain high-quality encyclopedic articles is an area of active research. In order to address this question, researchers need to build consensus around a sensible metric to assess the quality of contributions to articles. This measure must not only reflect an intuitive concept of “quality,” but must also be scalable and run efficiently. Building on prior work in this area, this paper uses human raters through Amazon Mechanical Turk to validate an efficient, automated quality metric.

Reliability of User-Generated Data: the Case of Biographical Data in Wikipedia

Title: Reliability of User-Generated Data: the Case of Biographical Data in Wikipedia

Authors: Robert Viseur

Abstract: Wikipedia is a collaborative multilingual encyclopedia launched in 2001. We already conducted a first research on the extraction of biographical data about personalities from Belgium in order to build a large database with biographical data. However, the question of the reliability of the data arises. In particular, in the case of Wikipedia, the data are generated by users and could be subject to errors. In consequence, we wanted to answer to the following question: are the data introduced in Wikipedia articles reliable? Our research is organized in three sections. The first section provides a brief state of the art about the reliability of the user-generated data. A second section presents the methodology of our research. A third section will present the results. The error rates that were measured for the birthdate is low (0.75%), although it is higher than the 0.21% score that we observed for the baseline (reference sources). In a fourth section, the results are discussed.

Rhizome and Wikipedia: A Humanities Based Approach Towards a Structural Explanation of the Namespace

Title: Rhizome and Wikipedia: A Humanities Based Approach Towards a Structural Explanation of the Namespace

Authors: Stephan Ligl

Abstract: In this paper, I describe the similarities between the rhizome according to Deleuze and Guattari with their six principles and the wikipedia’s main namespace on the one hand and the principles of a botanical rhizome and wikipedia’s main namespace on the other hand and try to compare them.
