Knowledge diversity, sentiment and opinion bias play an important role in Wikipedia articles and are an inevitable part of the process of creating community-based information entries. However, the general aim of a Wikipedia article is to cover a topic in an objective and balanced way, in order to ensure the accuracy of the details and achieve encyclopedic worth. In this workshop we present a set of tools that help to monitor and manage articles, contributing towards the overall goal of achieving higher completeness and objectivity.

Detailed proposal

While creating or updating articles, it is common that users cannot refrain from expressing parts of their personal opinion or sentiment on the topic. Furthermore, versions of the same article in different languages can express diverse view points. Knowledge diversity is an inevitable part of the Wikipedia articles. In an initial attempt to provide some support for exploring and managing this diversity, especially in the context of achieving completeness of the content and enabling quality assurance, we have developed a set of supporting tools.

The results that will be presented during the workshop are developed within the scope of the RENDER (Reflecting Knowledge Diversity) EU project, which focuses precisely on information diversity on the WWW and in particular in Wikipedia. Preliminary prototypes have already presented during the Wikimania 2011 in Haifa and the Wikimania 2012 in Washington D.C. However, this is the first time where the maturity of the tools allows for the condition of a more practical-oriented and hands-on session.

Goals of the workshop: Through this workshop we aim to raise the awareness of the problems that occur as a result of knowledge diversity. This is an inseparable part of the process of generating articles in a collaborative manner, however, up-to-date there are no concrete approaches or supporting tools for handling opinionated or sentiment-rich articles. For this purpose, we aim to introduce a set of practical tools that enable some level of monitoring and management in this context.

Structure of the workshop and learning outcomes: This workshop will consist of three sections. We will use an overall example through out the sections in order to illustrate the different issues and demonstrate the applicability of the tools.

  • Introduction to knowledge diversity within articles, motivation of the need for monitoring and managing, sentiment, opinions and conducting quality assurance
  • Description of a simple use case detecting and exploring diversity in articles, with the help of the tools
  • Practical and hands-on introduction of the tools, in the context of the described use case

The tools that we are going to introduce: Overall the RENDER project produced a variety of tools for different Web settings. In the context of Wikipedia we are going to present four tools for article monitoring and management.

  • The article list generator enables authors to create individual lists of articles. The users can choose certain categories and specify filters to search (e.g. for articles without an image). Currently, the list generator works for the English, German and French Wikipedia. Further languages versions will be added in future.
  • The article monitor aims to help users to get a quick overview about the currently viewed Wikipedia article. The monitor sums up several statistics and provides different analysis approaches like fact coverage and timeliness. Further approaches or assessment results can be included very easily if required. The results don’t vote for or against an article. The user can use all information to reason about the quality and probably to get hints for contributing.
  • WIKIGINI focuses on identifying the authorship of individual text parts and snippets within Wikipedia articles. WikiGini is an application for measuring and analysing the change of ownership of text in an article over time. As a measure for ownership the Gini coefficient shows the inequality in the distribution of ownership in a text.
  • Link ExtrActor explores the thematic coverage of a Wikipedia article by analysing wikilinks. Wikipedia articles contain internal links (wikilinks) to other articles. These are usually inserted to give further explanation about major terms or concepts. We use these internal links as one approach to analyse the thematic coverage of an article.

In summary, we will offer a session that addresses the issues related to knowledge diversity reflected in opinionated and biased articles. We present a specific use case that demonstrate the related problems and offer a set of tools that can be directly used to monitor and manage the creation and editing of articles. Furthermore, we share our gained experience and despite the fact that the RENDER project will end in September this year, we will continue to further develop the here presented tools and work on making deployment for more language versions. As part of the workshop we are also working to gather valuable feedback on the provided functionaries and on further implementations that are required in oder to support specific editing or maintenance tasks.
